1) fine grain strengthening 细晶强化 1. The effect of carbon in various states on the role of fine grain strengthening of high purity iron was investigated by tensile tests at room temperature and optical microscopy. 通过调节热处理条件使微量碳处于完全固溶状态、析出状态或偏析在晶界 ,利用室温...
细晶强化 (Fine Grain Strengthening) 细晶强化,是指通过晶粒粒度的细化来提高金属的强度,多晶体金属的晶粒边界通常是大角度晶界,相邻的不同取向的晶粒受力产生塑性变形时,部分施密特因子大的晶粒内位错源先开动,并沿一定晶面产生滑移和增值。滑移至晶界前的位错被晶界阻挡。这样一个晶粒的塑性变形就无法直接传播到相...

When the grain size measures 13 μm, the alloy can achieve a yield strength exceeding 900 MPa due to the combined impact of fine grain strengthening in the recrystallized microstructure and dislocation strengthening in the non-recrystallized microstructure. Additionally, the work hardening capability ...
SS400 is a new generation steel with ultra-fine grain strengthening. The effect of welding process on the fatigue performance is concerned recently. The fatigue crack growth rate has been investigated for SS400 and its welded joint based on the ASTM E647-83 specification. In the test the ...
