回火抗力
With the same surfacing parameters, the metallographic structure, hardness, resistance to tempering and abrasive resistance of the deposited metal were compared and analyzed.
在堆焊工艺参数相同的情况下,对微观金相组织,宏观硬度、抗回火性及耐磨性的研究,分析比较了两种药芯焊丝堆焊熔敷金属的力学性能。
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。
