45钢与T10钢热处理组织和性能比较研究

摘 要

为探讨热处理工艺对45钢及T10的影响，本文对45钢与T10做了退火，正火，淬火以及低温回火，中温回火，高温回火的热处理工艺处理,观察金相组织,测量布氏硬度，再对得到的数据进行系统详细的分析比较，结果表明再相同热处理下含碳量是影响45与T10在金相组织形成，硬度差异的主要因素。发现了随着含碳量的增加，钢的硬度、强度增加，塑性、韧性降低的结果。

Abstract

To explore the Heat Treatment on 45 Steel and T10, the paper made of 45 steel and T10 annealing, normalizing, quenching and tempering, tempering temperature, tempering the heat treatment process, observe the microstructure, measuring cloth hardness, and then the data is systematically detailed analysis and comparison results show that the carbon content and then heat-treated at the same affect with T10 45 formed in the microstructure, hardness difference of the main factors. Found that with increasing carbon content steel hardness, strength increases, lower ductility, toughness results.

Keywords: heat treatment, microstructure, hardness, 45, T10
