The addition of third elements may help transform brittle D022-structured lightweight Al3Ti to a relatively ductile L12-structured (Al, M)3Ti (where M represents the third elements), thus increasing the ductility at the expense of hardness. Such a transf

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...
A Mn-modified Ll 2 Al 3 Ti-base intermetallic was subjected to compressive deformation at room temperature under superimposed hydrostatic pressures up to 1000 MPa. It is found that its yield strength is essentially unaffected by hydrostatic pressure. The apparent work-hardening rate of true stress-...
L12 die Al3Ti basic lightweightPROBLEM TO BE SOLVED: To provide an easily producible and inexpensive Ll2 type Al3Ti based lightweight heat resistant alloy which has excellent cold tensile ductility and high temperature oxidation resistance.橋本 健紀...
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 ...
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...
