超高强铝合金热处理工艺研究

A Study of the Ultra High Strength Aluminium Alloy Heat Treatment Process

研究了超高强铝合金的固溶处理和不同时效工艺。结果表明，ＤＳＡ处理可明显改善超高强铝合金的强度和抗腐蚀综合性能。同时讨论了ＤＳＡ处理改善合金强度和抗蚀性能的机理。

The solution treatment and different ageing process has been studied The results show that DSA treatment can improve obviously combination of strength and corrosion resistance of the ultra high strength aluminium alloy The priciple of improving the strength and corrosion resistance of the alloy by DSA treatment has been discussed The surface and average stress were determined for the plasma sprayed ZrO 2 N.
