工艺参数对5754铝合金组织和性能的影响
Effect of Process Parameters on Microstructure and Properties of 5754 Aluminum Alloy
摘要:
以5754铝合金为研究对象,研究了变形量、退火温度、退火时间等因素对5754合金板材组织和性能的影响。结果表明,5754合金板材加工硬化现象显著,随着变形量的增加,其抗拉强度和屈服强度不断增大,而延伸率则逐渐降低,且5754合金板材退火时间对力学性能的影响小于退火温度。
Abstract:
Taking the 5754 aluminum alloy for automobile as the research object, the effect of cold rolling deformation, heat holding time and heat holding temperature on the properties and microstructure of alloy were studied. The results show that the work hardening of 5754 alloy sheet is significant. With the increasing of cold rolling deformation, the tensile strength and yield strength of alloy plates increase gradually, while the elongation decreases. And the annealing time on the me-chanical propertied of 5754 aluminum alloy is less sensitive than the annealing temperature.
