    • Ductility of a high-magnesium or high-aluminum content workpiece is increased during plastic deformation of the workpiece. When the workpiece is plastically deformed in a sealed chamber comprising a high concentration of dry hydrogen gas, the workpiece exhibits increased ductility compared to the ductility of a workpiece of identical composition that is similarly deformed in air. Enhanced ductility is quantified for several workpieces comprising aluminum and magnesium alloys in various forms including extruded sheets, drawn bars, rolled plates, and piston casts. Enhanced ductility is evident over a wide range of processing temperatures without a significant decrease in strength characteristics.
    • 在工件的塑性变形过程中,高镁或高铝含量的工件的延展性增加。 当工件在包含高浓度干燥氢气的密封室中塑性变形时,与在空气中类似变形的相同成分的工件的延展性相比,该工件表现出较高的延展性。 对于包括挤压片材,拉伸棒材,轧制板和活塞铸件的各种形式的铝和镁合金的几个工件来说,增强的延展性是量化的。 增强的延展性在宽范围的加工温度下是明显的,而强度特性没有显着降低。
