This is the third progress report on the melt quality of 85-5-5-5 red brass, and deals with the effect of hydrogen bubbling in the melt on the gas absorption and the behavior of dissolved gas. Hydrogen bubbling is more effective on the gas absorption in the melt than the case of water vapor bubbling or exposing mentioned in the previous paper, and the fracture characteristics of the chill-blocks may vary with the more gas absorptions in the same way as in the latter case. A consideration is also turned to the general phenomena of gas absorption in 85-5-5-5 red brass.
