Common Microhardness Tester
Micro Hardness Tester
A micro hardness tester is a device used to measure the hardness of a material at a microscopic scale. It can be used to determine the materials resistance to indentation or deformation by measuring the hardness of a sample or a region of a sample. It is used in many industri......
Metallographic diagram of 5Cr21Mn9Ni4N (gas soft nitriding)
Abstract
This paper introduces the metallographic features of X5Cr21Mn9Ni4N stainless steel, which is a austenitic stainless steel with nitrogen-containing Gas Nitriding (GN). The samples were subjected to etching of Keller solution to observe their internal structural features. The samples showe......
