| 摘 要： | 研究不同加钛方式和钛含量对铸造A356铝合金常温低周疲劳行为的影响,分析合金疲劳断口的形貌特征.结果表明:4种A356合金均表现出明显的循环硬化行为,但Ti含量(质量分数)为0.14%的合金比Ti含量为0.10%的合金具有更高的循环硬化率.在低应变时,加钛方式对合金的循环硬化影响相近;而在高应变时,电解加钛A356合金...

| Abstract: | Effects of the method of Ti-alloying and Ti contents on the low cycle fatigue(LCF) behavior of cast A356 alloys at room temperature were investigated,and the morphologies of fracture surfaces were analysed.The results show that four kinds of A356 alloys exhibit the evident cyclic hardening behavior,and the A356 alloys with 0.14%Ti(mass fraction) exhibit higher cyclic hardening rate than the alloys with 0.1%Ti.The cyclic hardening behavior influenced by method of Ti-alloying has similar trend when tested at ... |
