摘要
研究了2Cr13钢的硬度、屈服强度和疲劳寿命;用SEM(扫描电镜)测量了2Cr13中夹杂物的化学成分。实验发现,材料的疲劳寿命因合金中的夹杂物而显著降低,约为不含夹杂物合金疲劳寿命的一半。
The hardness, yield strength and fatigue life of 2Cr13 steel were investigated. SEM （scanning electronic microscopy） was used to determine the chemical composition of inclusions and matrix of the alloy. The results show that the fatigue life of the alloy drops significantly when some inclusions are mixed in the alloy, which is one half of that of the homogenous alloy without inclusions.
