摘要: 通过XRD、OM、EDS、SEM和万能试验机等方法,研究了不同冷变形量对TC4合金微观组织及力学性能的影响以及相同再结晶处理对不同冷变形量合金再结晶程度的影响。结果表明,冷轧制使得TC4合金产生加工硬化,相较固溶试样,35%和48%冷变形量试样的抗拉强度分别提高451 MPa和228 MPa。再结晶工艺相同时,随着变形量的增大,合金的抗拉强度逐渐降低。

Abstract: Effect of different cold deformations on microstructure and mechanical properties of TC4 alloy and effect of the recrystallization treatment on the degree of recrystallization of the alloy with different cold deformations were investigated by means of XRD, OM, EDS, SEM and universal testing machine. The results show that cold rolling makes TC4 alloy work harden, and the tensile strength of the specimens with 35% and 48% cold deformation increases by 451 MPa and 228 MPa than the solution specimens, respectively. Under the conditions of the same recrystallization process, it is found that as the deformation increases, the tensile strength of the alloy gradually decreases.

Key words: TC4 alloy, cold rolling, deformation, recrystallization
