摘要

研究了热锻和热处理参数（奥氏体化温度、淬火介质和回火温度）对 AISI D2 钢的微观结构和机械性能（硬度、冲击强度和耐磨性）的影响。研究发现，在热锻过程中，钢结构中的初级 M7C3 碳化物转变为次级 M23C6 碳化物。这导致了钢的硬化，因为二次 M23C6 碳化物是提高钢的强度和耐磨性的主要因素。锻造后进行淬火有助于增加二次碳化物的数量，并使其在钢结构中的分布更加均匀，从而提高钢的硬度、韧性和耐磨性。

A Study on the Effect of Prior Hot Forging on Microstructure and Mechanical Properties of AISI D2 Steel After Quenching

The effect of hot forging and heat treatment parameters (austenitization temperature, quenching medium and tempering temperature) on the microstructure and mechanical properties (hardness, impact strength and wear resistance) of AISI D2 steel has been studied. It has been established that during hot forging, the primary M₇C₃ carbides in the steel structure are transformed into secondary M₂₃C₆ carbides. This leads to hardening of the steel, since the secondary M₂₃C₆ carbides are the main factors in its increased strength and wear resistance. Carrying out of quenching after forging contributes to an increase in the number of secondary carbides and their more uniform distribution in the steel structure, which leads to an increase in its hardness, toughness, and wear resistance.
