“…The most widely used reinforcement for MoSi 2 compound in high temperature applications is the WSi 2 phase as it can significantly enhance the strength at elevated temperatures [1], thermal stability, fracture toughness, and hardness of MoSi 2 [15,16]. In addition, the WSi 2 phase can form a solid solution with MoSi 2 , forming MoSi 2 -based composites with increased strength [11,17].…”
