Abstract Scope |
MoSiBTiC alloys have great potential as ultrahigh temperature materials. However, the high-temperature strength, room-temperature fracture toughness, and oxidation resistance of MoSiBTiC alloys have a trade-off relationship with each other, so there is a need to establish an appropriate balance between these material properties and to further improve their performance. The most important issue to be addressed in the future is microstructure control. Additive manufacturing may be one of the most promising methods. The rapidly solidified MoSiBTiC alloys simulating the effect of rapid solidification by additive manufacturing have microstructures that are one order of magnitude finer than those produced by the conventional arc melting method and exhibit good oxidation resistance at temperatures exceeding 1000ºC. The development of new melting and casting processes for ultrahigh temperature materials would be important in the future. |
