Metallographic diagram of 50 steel (intermediate frequency quenching, low temperature tempering)
The microstructure of 50 steel (medium frequency quenching, low temperature tempering) is mainly composed of eutectoid structure, the matrix is composed of ferrite and cementite, and the retained austenite converted from martensite ( M + A) is present in the quenched steel. Whenlow temperature tem......
Morphology and X-ray energy spectrum of FeO·Cr2O3 spinel inclusions in GCr15 steel
，
GCr15 Steel is a low-carbon, high-chromium martensitic alloy steel made by adding 1% chromium to ordinary ordinary steel, which increases its corrosion resistance and abrasion resistance. The high chromium content and heat treatment process of GCr15 improves its hardness and increases wear resis......
