high-carbon steel heat treated 中文意思是什麼
high-carbon steel heat treated
解釋
熱處理過的高碳鋼-
We studied the effect of laser quenching ( harden by phase transformation ) on some representative mould steels. through measuring the rigidity on the surface of samples treated by laser heat treatment, and through photographing microstructures of the steel surface, we find many reasons attribute to high hardness. these reasons include ultra - fine grains, high density dislocation and more content of carbon in martensite
我們研究的是激光淬火對幾種典型模具鋼的作用,通過對熱處理后的試樣的硬度分佈的測定,用金相和電鏡觀察金相組織的變化,認為激光熱處理產生高硬度的原因是晶粒細化、高的位錯密度和高的馬氏體含量。
