The role of direct chilling, retrogression and reaging treatment on mechanical properties of high strength aluminum alloy
(Trans Tech Publications, 2013-03)The effect of retrogression and reaging heat treatment on microstructure evolution andmechanical properties of 7075 Al alloy in direct chilling casting process was investigated. The subsequent heat treatment process comprised ... -
Sintering behavior and microstructure evolution of mechanically alloyed W–bronze composite powders by two-step ball milling process
(Elsevier, 2013-01)The miscibility of W in Sn and Cu is extremely poor. Sintering of W–bronze composites to their full density is proved to be difficult. To tackle this problem, the ball milling process of the W–bronze powder mixture proposed ...
