Alloy Design and Characteristics of high-alloy High Carbon DM6S Steel with Multiple Types of Ultra-fine Carbides
首发时间:2005-07-14
Abstract:On the basis of carbides transformation orderliness, the alloy composition design of the high-alloy high carbon DM6S steel was accomplished by phase-equilibrium thermodynamic calculation for Fe-Cr-W-Mo-V-C system. There exist multiple types of ultra-fine carbides and vary thin martensite in this steel. The range of quenching temperature of the steel is widened (980~1100℃), and quenching hardness is HRC60~63. There exists secondary hardening when tempering at high temperature after quenching at high temperature, and the highest hardness is HRC61.5.The reasons of ultra-fine carbides obtained in this steel are the presence of multiple types of carbides, more amount of MC(VC), and the addition of less nickel which slower diffusion rate of atoms.
