On comparison plate-like L12–Al3Ti precipitates form a kinked plate surrounded by four {112} planes in L10 matrix. The particular habit plane, orientation relationship and twin plane variants were carefully determined. It is found that these crystallographic and morphological features can be ...
L12变异合金高能球磨低温热处理以Al,Ti,X(X=Cr,Mn,Fe,Co,Ni,Cu等)高纯度粉末为原料,以高能球磨机和真空热处理炉为设备,将原料按Al3Ti或Al3Ti—X合金化学计量比配合,添加少量过程控制剂,适当控制转速,球料比,磨球直径等球磨工艺参数,在氩气保护下球磨30h后,在真空热处理炉中经过600～800℃低温热处理,成功...
The microstructures and mechanical properties of an Fe-modified L12alloy containing 7.5 at.% Fe have been investigated. This alloy has been determined to be essentially single phase following a homogenization heat treatment (HHT) at 1100°C for 100h, with a very small volume fraction of ...
Al_3Ti基合金Al_2Ti片层透射电子显微镜研究了含Ti25%和L12结构Al3Ti基合金在铸态和经1000℃进行压缩变形后的微观组织结构变化.试验结果表明,铸态合金中就有Al2T11相存在.doi:http://210.72.142.130/handle/321006/27817张立春,陈国良,彭继华,叶恒强材料热处理学报...

研究了含Ti25%的L12结构Al3Ti基合金在铸态和经1000℃进行压缩变形后的微观组织结构变化.试验结果表明,铸态合金中就有Al2TiI相存在.经1000℃进行压缩变形后合金中Al2Ti细片层开始逐渐粗化,其粗化方式有两种:其一是Al2Ti片层通过消耗周围细小的Al2Ti片层而长大;其二是在再结晶晶界处位错发射导致较粗大Al2Ti片...
The L12-type long-range ordered γ′ intermetallic alloys Ni3Al, Ni3Si and Co3Ti have attracted much attention because of their potential as high temperature structural materials 1, 2, 3, 4, 5, 6. However, such intermetallics suffer from low-temperature brittleness and inadequate high-temperatu...
