Non Ferrous Materials

Materials science; Metallurgy

Nonferrous materials and their alloys do not contain iron as a principle ingredient, although they may contain small percentages. These include the radioactive metals uranium,aluminum,nickel, ...

Metamaterials

Materials science; Metallurgy

A meta material is a metallic or semiconductor substance whose properties depend on its inter-atomic structure rather than on the composition of the atoms themselves. Certain meta materials bend ...

Martensitic stainless steels make up the cutlery grades. They have the least amount of chromium, offer high hardenability, and require both pre- and postheating when welding to prevent cracking in ...

Ferritic stainless steels

Materials science; Metallurgy

Ferritic stainless steels have 12 to 27 percent chromium with small amounts of austenite-forming alloys.

Cyaniding

Materials science; Metallurgy

In this process,the parts to be heat treated are immersed in a liquid bath at 800 to 960 degree of NaCN with the concentration varying between 25 and 90 percent.

Carbonitriding

Materials science; Metallurgy

This process is specifically used for improving wear resistance of mild,plain carbon or very low alloy steels.Carbonitriding is carried out at low temperatures in the range 800 to 870 degree in a gas ...

Nitriding

Materials science; Metallurgy

Nitriding is most effective for those alloy steels which contain stable nitride forming elements such as aluminum,chromium,molybdenum,vanadium and tungsten.Nitriding is carried out in a ferritic ...
