TZM is one of the most important Mo-based alloys which has a composition containing 0.40–0.55 wt% titanium, 0.06–0.12 wt% zirconium and 0.010–0.040 wt% carbon. It is a possible candidate for high temperature applications in a variety of industries. However, the rapid oxidation of TZM at high temperature in air atmosphere can be considered as a main drawback. In this study, TZM alloy was sintered by using spark plasma sintering (SPS) with addition of B4C in two different techniques. Both sintering and boriding process were performed in a single step. B4C was dispersed in the matrix or molded as a sandwich in order to increase oxidation resistance by formation of Mo-B based phases during the sintering process. The effects of B4C addition was investigated in terms of oxidation resistance, densification behavior, Vickers hardness and microstructure.
