摘要:

通过XRD、OM、SEM和压缩实验等方法，研究了热处理对选区激光熔化制备Ti-5Al-5Mo-5V-3Cr-1Zr (Ti55531)合金多孔材料组织和力学性能的影响。结果表明，在750~900℃之间进行固溶处理随后于500~600℃之间进行时效处理，Ti55531合金多孔材料的孔梁组织由α相和β相组成。随着固溶温度升高，孔梁中初生α相含量减少，次生α相含量增加，孔梁母材抗压强度升高但塑性降低，造成其韧性变差。随着时效温度的升高，孔梁中初生α相形状、尺寸和含量无明显变化，次生α相的含量减少而尺寸增加，孔梁母材抗压强度降低，塑性增加，使其韧性提高。Ti55531合金多孔材料抗压强度与其孔梁母材韧性密切相关，通过热处理调节孔梁母材强度和塑性匹配，提高其韧性，能够有效改善多孔材料的压缩强度。

Abstract：

Lightweight metallic cellular components with high strength have received extensive interest because they are desirable for structural components. Previously, titanium alloy cellular structures were formed using additive manufacturing with the selective laser melting or electron beam melting technique. Numerous techniques have been developed to improve their strength. Most of these studies have focused on structure topology design. The relationship between the strength and mechanical properties of their strut parent materials has gained considerable attention. XRD, OM, SEM, and compression tests were used to investigate the effects of heat treatment on the microstructure and mechanical properties of Ti-5Al-5Mo-5V-3Cr-1Zr (Ti55531) alloy porous materials prepared through selective laser melting. The results show that the microstructure in struts consist of α and β phases after solution treatment at a temperature between 750^oC and 900^oC followed by an aging treatment at a temperature between 500^oC and 600^oC. The volume fraction of the primary α phase in the struts decreases as the solution temperature rises, whereas the volume fraction of the secondary α phase increases. The strut parent material's compressive strength increases but its elongation decreases, resulting in a decrease in toughness. With the increase of aging temperature, the shape, size, and volume fraction of the primary α phase in the strut do not change considerably, whereas the volume fraction of the secondary α phase decreases and the size increases. The strut parent material's compressive strength decreases while elongation increases, increa-sing toughness. The compressive strength of the examined porous alloy is strongly connected to the toughness of the parent material of the struts, which can be effectively improved by adjusting the strength and plasticity of the struts through heat treatment. The above results will guide the design of lightweight metallic cellular components with high strength.
