Powdered steel Crucible CPM® S125V™
CPM® S125V™ is a high-alloy martensitic stainless tool steel manufactured by Crucible Industries (USA). The corrosion resistance of the alloy is comparable to ZDP-189, that is, it is quite high. Steel ZDP-189 contains 20% chromium versus 14% for CPM S125V. The amount of carbon is about the same. It would seem that 125ya should rust more, but in ZDP-189 much more chromium goes into carbides than in S125V, where vanadium also goes into carbides. As a result, the chromium content in the solid solution for both steels is not so different.

Recently, many knife manufacturers have abandoned the CPM S125V, primarily due to the complexity of the finish. Custom craftsman Phil Wilson (Phil Wilson) said that handmade satin S125V takes three times longer than for CPM 10V - one of the most difficult steels (more or less mass-produced).

The steel is made using the technology of amorphous metal alloys, better known among knife makers and hobbyists under the acronym CPM (Crucible Particle Metallurgy). The CPM process makes it possible to produce a very uniform, high quality steel that is characterized by superior stability, uniformity and toughness compared to steels from traditional heat production.

Powdered high speed steel was developed in Sweden in the late 60s of the last century. The powder metallurgy method makes it possible to introduce more alloying elements into the steel without reducing the strength and machinability.

Powder steel, unlike ordinary steel, is fed in molten form through a special nozzle through a stream of liquid nitrogen. Steel quickly hardens into small particles. The result is a powder with a uniform arrangement of carbides (the place of accumulation of carbides is the place where cracks originate). Carbides perform the same function in the composition of steel as cobblestones on the street: they (carbides) are harder than the steel surrounding them, and contribute to its increase in wear resistance.

The resulting powder is sieved and placed in a steel container in which a vacuum is created. Next, the contents of the container are sintered at high temperature and pressure - thus achieving material homogeneity. This process is called hot isostatic pressing. The steel is then pressure treated. The result is a high speed steel with very small carbide particles evenly distributed in the steel substrate. The resulting steel can be rolled in the traditional way, as well as serial grades of steel, resulting in its increased strength.

Differences in the wear resistance of different grades of powder steel are explained by the presence of different carbides in their composition in different proportions and with different distribution uniformity throughout the steel volume. Of two steels having approximately the same hardness, the more wear-resistant will be the one in which there are more carbides or they are harder.

Steel composition:

C 3.3% - the carbon content in the alloy is 3.3%. Carbon is the most important element in steel, it increases its strength and gives the metal good hardness.

Cr 14.0% - the chromium content in the alloy is 14.0%. Chromium is a greyish-white lustrous hard metal. Chromium affects the ability of steel to harden, gives the alloy anti-corrosion properties and increases its wear resistance. Contained in stainless steel of any brand.

Mo 2.5% - the molybdenum content in the alloy is 2.5%. Molybdenum is a silvery white metal. Molybdenum is a hard-melting element, it prevents brittleness and brittleness of the blade, giving it the necessary rigidity, making it sufficiently resistant to high temperatures.

V 12.0% - the content of vanadium in the alloy is 12.0%. Vanadium is a grayish-white lustrous metal with great hardness. It is responsible for elasticity and enhances the properties of chromium, makes the metal inert to aggressive chemical environments.

It is worth remembering that when using a knife for its intended purpose and with careful handling, the knife will serve you for a very, very long time.


 

 Ironwood - iron wood - handmade knives

Ironwood - Ironwood

iron wood

In nature, ironwood is extremely rare, so it occupies an honorable place in the Red Book. However, in its properties, each iron tree is not inferior to the density of cast iron. Its bark can withstand fire from firearms, but at the same time it sinks hopelessly in water. It should be noted that this is not a separate class of trees, but a whole group collected from different species. It includes several dozen species of plants with unusually dense wood. They can be found on every continent. Moreover, raw materials are used both in the industrial industry and in medical practice.

What's special about these trees?

iron wood floor

It is quite difficult to recognize the “stone” species of a perennial plant with the naked eye. Especially if they are on the verge of extinction. However, they are characterized by the following features:

  • the age of such centenarians is at least 2 hundred years;
  • wood fiber is resistant to corrosion processes and does not deteriorate under the influence of strong acids;
  • the bark contains many tannins that protect their “hosts” from all kinds of parasites, as well as from rot fungus;
  • the log will definitely go under water, since the density of the wood is 1 t/m³, taking into account the humidity of 12%, for this reason such species grow quite slowly;
  • the height of each exceeds 25 meters, and the girth of the trunk reaches more than 200 cm.

huge trunk

All these properties are necessary for ironwood to survive in the harshest climatic conditions. Sudden temperature changes in Russia, African drought or humid European climate cannot harm this natural phenomenon. These types of trees adapt well to any unfavorable environment. To do this, they are equipped with a considerable number of devices, ranging from the unique structure of the trunk/roots to the chemical composition of the bark. In this regard, they are widely used in production:

  • furniture;
  • building structures;
  • cars;
  • cosmetics;
  • decorative elements;
  • underwater technology

Mammoth tusk: a jewel mined in permafrost

 

Most of our contemporaries are a mammoth - “a monster, mischievous, huge...” A large, disproportionately built elephant. A fierce beast, densely overgrown with dense shiny or long brown and patchy hair. A four-legged hero with heavy tusks at the ready, fearlessly chasing polar bears. Or he runs embarrassedly from a handful of furious bipeds... This is what a mammoth is in the performance of artists from science.
Are mammoths extinct?

It is generally accepted that mammoths lived as long ago as dinosaurs. However, scientists have reliably established that the last herds of mammoths lived on Wrangel Island about three and a half thousand years ago. The Pyramid of Cheops was already more than a thousand years old by that time. Moses was just preparing his fellow tribesmen for a forty-year dessert trip. The Mediterranean volcano Santorini, having exploded, buried the Mycenaean civilization a hundred years ago.

These are herds; individual families of mammoths, according to lovers of circumpolar hunting solitude, exist safely to this day. Whether this is true or not is unknown for sure. However, there is no doubt that in the past mammoths lived everywhere in Europe, Asia, and America.

Permafrost is the best refrigerator for mammoth bones

The mammoth bone cemetery is everywhere: in France, in the Czech Republic, in Ukraine. But only where the earth has been in a state of permafrost for thousands of years is a mammoth ivory kept in its original (or almost original) form. One of the largest burial sites in the world is Yakutia, where large quantities of this highly valuable material are still mined annually. According to experts, potential resources in the North Yakutsk province may be about 450 thousand tons.

Man at all times highly valued the fossil mammoth tusk. Dense, strong, massive, often white, usually yellowish, often colored with natural color by mineral salts, mammoth bone has been used for many centuries as a raw material for bone carving.

A material that is worthily appreciated by kings and rulers all over the world!

Tsar Alexei Mikhailovich, the father of Peter the Great, introduced a state monopoly on mammoth ivory back in the mid-seventeenth century. On his initiative, the extraction and supply of mammoth ivory to the bone-carving workshops of Kholmogory and Moscow (Armory Chamber) became permanent.

Peter the Great, fascinated by crafts, carved a snuff box from mammoth bone with his own hands. Foreign craftsmen also liked the material: among the goods traditionally supplied from Russia to the West, there was always a place for the bone of an extinct animal.

The only one allowed

Today, mammoth ivory is the only highly valuable bone material allowed for extraction and use. Elephant tusk, the well-known ivory, has been classified as a prohibited material. Similar decisions were made regarding the sperm whale tooth (due to the complete abandonment of whale hunting) and walrus tusk (which is caught by northern peoples in small quantities).

Moose antler and stream (the tubular femur of large animals) are not capable of producing the visual effect produced by mammoth bone products. The internal glow of the figures, the warm shades of the living body, the unsurpassed plasticity of the smallest details - these are just some of the advantages inherent in mammoth tusk.

Versatility, nobility, uniqueness

The physical qualities of the mammoth tusk massif are unique. Modern technologies are only trying to create substances with properties approaching natural mammoth bone. Allowing for the finest elaboration of details, making it possible to create the illusion of soft draperies of clothing that naturally fall, mammoth tusk has deservedly become the most sought-after material for bone carving.

Mammoth ivory with a homogeneous structure is in particular demand. The uniform coloring of the bone mass, the absence of cracks and other defects allows the artist to create without taking into account the quality of the material. However, the integrity of a solid mammoth bone is already rare and defects in the material force the artist to be more inventive in composition, which ultimately turns into an additional advantage in sculpture.
