Abstract
本发明提供了一种抑制Al‑Mg‑Si‑Cu‑Mn‑Cr铝合金形变再结晶以及粗晶的热处理方法,通过对Al‑Mg‑Si‑Cu‑Mn‑Cr铝合金进行多级均匀化热处理,使合金铸锭在均匀化热处理过程中析出高密度、微纳米级别、分布均匀的α‑Al(MnCr)Si相;从而有效抑制形变过程中合金粗大再结晶晶粒的出现,有效解决了Al‑Mg‑Si‑Cu‑Mn‑Cr铝合金生产过程中常见的粗大再结晶问题。本发明符合高强度铝合金的发展方向,解决了交通运输用铝合金的工业应用难题。
The invention provides a heat treatment method for suppressing deformation, recrystallization and coarse-graining of Al-Mg-Si-Cu-Mn-Cr aluminum alloys. Heat treatment, so that the alloy ingot precipitates high-density, micro-nano-level, uniformly distributed α-Al(MnCr)Si phase during the homogenization heat treatment process; thus effectively suppressing the appearance of coarse recrystallized grains of the alloy during the deformation process, effectively solving the problem. Coarse recrystallization is a common problem in the production of Al-Mg-Si-Cu-Mn-Cr aluminum alloys. The invention conforms to the development direction of high-strength aluminum alloy, and solves the industrial application problem of aluminum alloy for transportation.
