3.热处理锻造铝合金多数要进行固溶处理、淬火、时效处理等。不可热处理合金也要进行退火处理。固溶处理是在固相线以下的温度下保持30分钟到4小时,使析出硬化的溶质元素完全固溶。淬火是在冷水或温水中进
3. Heat treatment Forgings aluminum alloy solution treatment, quenching, aging treatment. Non-heat-treatable alloys are also annealed. The solution treatment is carried out at a temperature below the solidus temperature for 30 minutes to 4 hours to completely dissolve the precipitation-hardened solute elements. Quenching is in cold water or warm water into
