某些合金的改进工作与热处理方面的一些革新相结合将使锻件获得更好韧性和强度.目前,正把热处理方面的一些革新用于生产,从而使7000系铝合金的某些主要性能得到改善.例如,在热处理7050铝合金锻件的过程中使用了合成淬火剂.其中一种效果是锻件在外形尺寸上更稳定,使锻件更适合于随后的机械加工.使用合成淬火剂的第二个优点是减少锻造铝合金中的残余应力.这同样也能改善7050铝合金的抗应力腐蚀裂纹能力.另一种革新包括采用称为中间形变热处理的方法,即在处理7475铝合金锻件过程中使用中间形变热处理.
Some of the alloy improvements combined with some innovations in heat treatment will result in better toughness and strength for forgings and some of the innovations in heat treatment are currently being used to produce some of the key properties of 7000 Series aluminum alloys For example, synthetic quenchants are used in the heat treatment of 7050 aluminum forgings One of the effects is that the forgings are more dimensionally stable, making the forgings more suitable for subsequent machining The second advantage of using synthetic quenchants Is to reduce the residual stress in the forged aluminum alloy.This can also improve the ability of the 7050 aluminum alloy to resist stress corrosion cracking.Another innovation includes the use of a method called intermediate deformation heat treatment that is used in the process of processing 7475 aluminum forgings Deformation heat treatment.
