Abstract

In this paper, TiB reinforced Ti-6Al-4V matrix composites were successfully fabricated using a spark plasma sintering, hot rolling and heat treating process. (Transformed β-Ti + secondary α-Ti) domains were formed in TiB/TMCs after heat treatment. The size of these domains increases from 2.5 μm to 4.6 μm with the increase of solution time. The aspect ratio of whiskers monotonously decreases along with the solution time extending. The highest ultimate tensile strength of 1332 MPa and yield-strength of 1315 MPa were achieved by (940 °C, 15min+ water-quenching+537 °C, 4h) TMC.
