What is Austenite? Austenite is a metallic, non-magnetic solid solution of carbon and iron that exists in steel above the critical temperature of 1333°F ( 723°C). Its face-centered cubic (FCC) structure allows it to hold a high proportion of carbon in solution. In many magnetic alloys, the Curie ... Read More

The Advantage of Vickers Hardness Test The advantage of Vickers hardness test is that its hardness value has nothing to do with the test force. As long as the material is of uniform hardness, the test force can be selected arbitrarily and the hardness value will not change. This is equivalent to ... Read More

What aspects should be considered when choosing a hardness tester? Before choosing a hardness tester, here are the main factors to consider: Test Load: This depends on the hardness of the material. For example, metals such as steel or alloys require test loads of up to 3000kgf, while soft metals ... Read More

Ferrite - iron oxide compound The interstitial solid solution formed when carbon dissolves in the interstices of the α-Fe lattice is called ferrite. It has a BCC structure and shows equiaxed polygonal grain distribution, denoted by the symbol F. Its microstructure and properties are similar to those ... Read More

Working Principle and Composition of Microhardness Tester Microhardness tester is a device commonly used to measure metal hardness in recent years.
