Research and progress of thermomechanical treatment of aluminium alloy 铝合金形变热处理工艺研究进展
2.
Combined thermomechanical treatment 组合形变热处理
3.
Thermomechanical treatment ( solution - cold - drawing - aging ) can increase alloys " strength greatly . the alloy in aging after cold - drawing was influenced by the interaction of precipitation and recrystauization . the precipitates not anly can strengthen the matrix but also can restrain recrystauization 形变热处理(固溶?冷拉?时效)工艺可大大提高合金时效后的最终强度，时效后形变热处理对电阻率影响很小。
