<正>The influences of RE-modification and Sr-modification on the hydrogen content and surface oxide film of A356 aluminum alloy melt were investigated. The hydr
The effects of thermohydrogen treatment on the microstructures of TC21 and Ti40 alloys as-cast were researched. The results show that the β phase content incre
The influence of heat treatment on the microstructure and damage tolerance property of Ti-6Al-2Zr-1Mo-1V titanium alloy was investigated. The large-thickness Ti
