Abstract

In this paper, the 2.6vol%TiBw/Ti6Al4V composites with network architecture were fabricated by hot press sintering (HPS) at 1100 °C for 1 h, and the quantitative relationships between phases and heat treatment temperatures were established. The results showed that the volume fraction phases changed linearly with a range of solution temperature (930–1010 °C) and aging temperature (400–600 °C). Moreover, the composites with equiaxed microstructure were obtained due to the static recrystallization after solution treated at 950 °C for 1 h and aging treated at 600 °C for 12 h. The ultimate high temperature tensile strengths were 772, 658, 392 and 182 MPa, and the elongations were 9.1%, 12.5%, 28.6% and 35.3% at 400, 500, 600 and 700 °C, respectively. In addition, fractured morphology analysis indicated the excellent strengthening effect of TiBw at a temperature below 600 °C. However, the strengthening effect was significantly reduced due to the debonding of matrix and TiBw at 700 °C and caused the cracks to propagate along the grain boundary.

摘要

本文通过1100 °C/1 h 真空热压烧结技术制备了2.6vol%TiBw/Ti6Al4V 网状增强钛基复合材料, 并建立了热处理参数与各相百分含量的量化关系。结果表明,在固溶温度930∼1100 °C 和时效温度 400∼600 °C 之间,各相百分含量与固溶、时效温度呈线性变化。并且经过950 °C/1 h 固溶处理与600 °C/ 12 h 时效处理后,由于热处理过程中发生了静态再结晶,钛基复合材料呈现等轴状。对等轴钛基复合 材料进行高温拉伸测试,结果表明,材料高温抗拉强度达到772 MPa(400 °C), 658 MPa(500 °C), 392 MPa(600 °C),182 MPa(700 °C),高温伸长率也分别为9.1%(400 °C), 12.5%(500 °C), 28.6%(600 °C), 35.3%(700 °C)。通过对材料高温断口的分析,发现TiB 晶须在600 °C 温度以下能够起到很好的增强 效果,但是当温度超过700 °C 后,TiB 晶须与基体发生脱粘现象,导致TiB 晶须的增强效果显著降低, 并且使裂纹沿着晶界扩展。
