挤压温度对2A12铝合金T4状态管材力学性能的影响

The Influence of Extrusion Temperature on Mechanical Properties of 2A12 Aluminium Alloy under T4 Condition

研究了挤压温度对2A12铝合金T4状态厚壁管材力学性能的影响。结果表明,挤压温度越高,管材的强度越高。当挤压温度为370℃时,管材的抗拉强度为450MPa,屈服强度为330MPa;挤压温度为400℃时,抗拉强度达到540MPa,屈服强度达到400MPa。

Analyzed the influence of extrusion temperature on the mechanical properties of 2A12 alloy thick tube which is T4 condition,the results express the extrusion temperature is higher,then the strength of tube will be higher.When extrusion temperature is 370℃,the tensile strength is 450 MPa,the yield strength is 300 MPa;when temperature is 400℃,the tensile strength is 540 MPa,the yield strength is 400 MPa.
