Abstract

The results of experimental studies to determine the influence of the parameters of pendulum surface plastic deformation (SPD) on the distortion of grains of carbon steel 45 are presented. It has been established that after pendulum SPD, the grains in the hardening zone change in size and shape, which affects the increase in microhardness. The dislocation density of steel 45 after SPD was also determined, which can be used to judge the increase in the strength characteristics of hardened parts.

摆动 SPD 过程中碳钢晶粒形状和位错密度的变化

摘要本文介绍了确定摆锤表面塑性变形（SPD）参数对 45 号碳钢晶粒变形影响的实验研究结果。结果表明，摆锤表面塑性变形（SPD）后，淬火区晶粒的尺寸和形状会发生变化，从而影响显微硬度的增加。此外，还测定了 SPD 后 45 号钢的位错密度，该密度可用于判断淬火零件强度特性的提高情况。

期刊介绍： Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
