多次回火,反复回火
In this paper, repeated quenching and tempering processing was used to not only refine the grain size and but also keep the microstructure as tempered sorbite. Good wear resistance is also desired to be obtained by the processing.
本文设计旨在既保留回火索氏体组织又能细化晶粒的多次调质热处理工艺,以期使其耐磨性得到提高。
Tempering treatment resulted in formation of tempered martensite and the spalling resistance under repeated strong impact abrasion working conditions was largely improved.
在反复强力冲击工况条件下,回火得到回火马氏体,抗冲击剥落能力大为增加。
