工程材料的常用性能指标及其含义[0]

Posted on 2023年11月14日 by

工程材料主要分为金属材料和非金属材料。

其中金属材料的指标较多,不同的场合对于其要求也不同。典型的包括材料的化学成分,力学性能,质量等级,热处理方式,表面处理方式,金相组织结构,温度对于各个性能的影响,疲劳曲线(C-S曲线)

  • 力学性能

GBT 10623-2008 金属材料 力学性能试验术语 等效ISO23718

主要包括,抗拉强度,断后伸长率,冲击吸收功,屈服强度(下屈服强度,上屈服强度),应力-应变曲线,弹性模量,硬度

 

  • 化学成分

GBT 13304.1-2008 钢分类 第1部分:按化学成分分类,等效ISO4948-1

主要分为:非合金钢,低合金钢,合金钢

GB 20878-2007不锈钢和耐热钢-牌号及化学成分

  • 质量等级

GBT 13304.2-2008 钢分类 第2部分:按主要质量等级和主要性能或使用特性的分类等效ISO 4948-2
