单级固溶处理对7136铝合金组织及力学性能的影响
Effect of Solution Treatment on Microstructures and Mechanical Properties of 7136 Aluminum Alloy
摘要
Abstract
The effects of solution treatment on the microstructures and mechanical properties of 7136 aluminum alloy extrusion plate were studied by OM,SEM,DSC and room temperature tensile test. The results show that the higher the solution temperature and longer time, the more coarse second phase dissolved. The overheated structure appears in the alloys when the quenching temperature is at 480℃. The trend of microstructure coarsening and recrystallization appears when prolongating the solution time is extended. The suited solution of the alloy is single-stage solution of 470℃ ,4 h. After solution and peak aging of (470℃ ,4 h) + (120℃ ,24 h) ,the ultimate tensile strength,yield strength and elongation are 698 Mpa,647 Mpa and 12. 8%,respectively.关键词
