Effect of hydrogen content and stress state on room-temperature mechanical properties of Ti-6Al-4V alloy YUAN Bao-guo(袁宝国), LI Chun-feng(李春峰), YU Hai-ping(于海平), SUN Dong-li(孙东立...; Abstract: This work aims to investigate the effects of hydrogen content......
, a rapid and reliable measurement system for hydrogen content in magnesium melt was set up with CPU controller and electric circuit. With this instrument, measurement experiments were carried out to determine hydrogen content in AZ91 melt. The results show that the actual hydrogen level of AZ91 melt under gas protection varies from 0.06 mL/g to 0.14 mL/g at the temperature range from 650 ℃ to 750......

is an extremely harmful element present in the forging of ingots, especially large ingots [1-4]. However, the hydrogen content is difficult to control during the electroslag remelting (ESR) process... in a continuous increase of hydrogen content during the remelting process. The hydrogen permeability of the slag dominates the resulting hydrogen content of the steel, especially when the remelting is carried out......
