ＬＤ２合金挤压材生产新工艺ＬＤ２合金属于Ａｌ－Ｍｇ－Ｓｉ－Ｃｕ系，其制品的常规生产工艺是；铸锭加热（４００℃）→挤压→固溶（５１５℃）淬火→时效（１５５～１６５℃，８～１５ｈ）。有时为了满足制品性能的要求，将单级时效改为双级时效。其制度为：一级时效（...
LD2 alloy extrusion material production process LD2 alloy belongs to the Al-Mg-Si-Cu system, the conventional production process of its products; ingot heating (400 ℃) → extrusion → solution (515 ℃) quenching → aging ~ 165 ℃, 8 ~ 15h). Sometimes in order to meet the requirements of product performance, the single-stage aging changed to two-stage aging. The system is: a ...
