摘要:
 摘要:为了研究热处理工艺对ZL114A铝合金组织和力学性能的影响,利用金相显微镜、扫描电子显微镜、透射电子显微镜、拉伸实验机等设备对不同热处理后的ZL114A铝合金进行组织观察和力学性能测试。结果表明,随着固溶温度从505℃升高到550℃,合金组织中的共晶硅依次发生熔断、球化和粗化等现象,而且硬度、抗拉强度和延伸率均出现先增加后降低现象,在535℃/12h时达到最大值,分别为897HB、280MPa和66%;当固溶温度达到550℃时,晶粒粗大,出现过烧现象,硬度和抗拉强度急剧降低,因此,适合的固溶工艺为535℃/12h。经此固溶工艺处理的ZL114A铝合金经不同温度6h时效处理,结果表明,随着时效温度从140℃升高到170℃,合金的抗拉强度从286MPa增加至345MPa,而延伸率则从62%降低至40%,在155℃时,其抗拉强度和延伸率分别为315MPa和52%,较铸态时抗拉强度提高了810%,延伸率提高了1080%。从企业对产品实际性能需求出发,最佳的热处理工艺制度为535℃/12h+155℃/6h。
Abstract:
 Abstract:In order to study the effects of heat treatment on microstructure and properties of ZL114A aluminum alloy, microstructure observation and mechanical properties test of ZL114A aluminum alloy after different heat treatment were investigated by optical microscope, scanning electron microscope (SEM), transmission electron microscope (TEM), and tensile testing machine The results show that, with the increasing of the solution temperature from 505℃ to 550℃, fuse, spheroidization and coarsening phenomenon occurred in eutectic silicon of 〖JP2〗ZL114A alloy, hardness, tensile strength and elongation were increased, reached the maximum value at 535℃/12h, 〖JP〗897HB, 280MPa and 66%, respectively At the solution temperature 550℃, because grain become coarse and arise overburnt feature, the hardness and tensile strength decreased dramatically Therefore, suitable for the solution process is 535℃/12h The solution treated ZL114A alloy was aged at various temperature for 6h, the results show that with the increase of aging temperature from 140℃ to 170℃, the tensile strength increased from 286MPa to 345MPa, while the elongation decreased from 62% to 40% At 155℃, the tensile strength and elongation were 315MPa and 52%, respectively Comparing with ascasting ZL114A alloy, the tensile strength increased by 81%, and elongation increased by 108% According to the actual demand of the enterprise, the optimum heat treatment process is 535℃/12h +155℃/6h
