Description

一种GH4033合金锻件焊接后的热处理工艺
技术领域
本发明涉及一种热处理工艺,具体涉及一种GH4033合金锻件焊接后的热处理工艺。
背景技术
GH4033合金在我国的应用较为广泛,特别是航空工业上的应用。GH4033材料标准的技术条件规定时效制度为700℃~800℃,保温8h,以50±10℃/h速率炉冷至600℃~700℃,保温8h,空冷。GH4033合金锻件经固溶处理后,按现有工艺(即真空钎焊+标准时效工艺),经真空钎焊和时效处理后力学性能检查时,发现一些锻件存在缺口持久性能不合格。经分析,主要原因是试验件经过真空钎焊后试样组织中δ相含量较少,晶界上几乎无δ相析出,造成缺口持久敏感。
发明内容
本发明提供一种GH4033合金锻件焊接后的热处理工艺,解决经重复钎焊的GH4033合金锻件的缺口敏感问题。
本发明的技术方案如下:一种GH4033合金锻件焊接后的热处理工艺,包括如下步骤:将GH4033合金锻件进行固溶处理,然后放入真空钎焊炉中,进行真空钎焊;将真空钎焊后的GH4033合金锻件放入真空炉中进行中间热处理,加热至800℃~850℃,保温1.5h,油浸快冷;将经过中间热处理后的GH4033合金锻件放入空气炉中,进行标准时效处理。
本发明的有益效果为:本发明采用真空钎焊+中间热处理+标准时效的热处理工艺,可以解决现有的GH4033合金焊接组件时效后缺口持久不合格问题,提高经重复钎焊的GH4033合金锻件的合格率,为后续建立零件及组合件检验标准提供依据。
具体实施方式
一种GH4033合金锻件焊接后的热处理工艺,包括如下步骤:将GH4033合金锻件进行固溶处理,然后放入真空钎焊炉中,进行真空钎焊;将真空钎焊后的GH4033合金锻件放入真空炉中进行中间热处理,加热至800℃,保温1.5h,油浸快冷;将经过中间热处理后的GH4033合金锻件放入空气炉中,进行标准时效处理。
