摘要
2024铝合金薄壁型材不能进行在线淬火,必须采用离线淬火,但是在离线淬火时极易出现变形。本文试验选用PAG淬火液替代水作为淬火介质,并通过不同浓度的PAG淬火液进行淬火对比试验,结合机械性能与变形等因素,选择适合的淬火液浓度以达到淬火液浓度与机械性能的平衡。
2024 aluminum alloy thin-wall profiles can not be quenched online,so it must use offline quenching,but deformation appear easily when offline quenching. In this paper,PAG quenching liquid is selected instead of water as quenching medium. The quenching contrast test is conducted by different concentrations of PAG quenching liquid. Combined with mechanical properties and deformation etc,the suitable quenching liquid concentration is chosen to achieve the balance of quenching liquid concentration and mechanical properties.
