The ability to degas molten aluminum is generally achieved by using an inert gas, typically introduced into the melt by a rotary degassing unit. This degassing process is limited by thermodynamic laws; when purge gas bubbles are introduced into the melt, they collect hydrogen as they float to the surface. The best possible situation is […]
Hydrogen embrittlement is a phenomenon in which a metal becomes brittle due to hydrogen absorption, its plasticity decreases, and it breaks on its own. This ruptured form of material is bound to cause unexpected accidents and pose a great threat to safety. With the extensive application of metal materials, most aluminum foundries use a rotary […]
