Room temperature fracture toughness and high temperature strength of T2/Moss and (Mo, Nb)ss/T1/T2 eutectic alloys in the Mo-Si-B system

Room temperature fracture toughness and high temperature strength of T2/Moss and (Mo, Nb)ss/T1/T2 eutectic alloys in the Mo-Si-B system

Multiphase Mo-Si-B alloys are potential candidates for ultra-high temperature application. The T2/Moss and (Mo,Nb)ss/T1/T2 eutectic alloys have been grown using an optical floating zone method. In this paper, their microstructure, fracture toughness at room temperature and strength at high temperatu...

Zusammenfassung:Multiphase Mo-Si-B alloys are potential candidates for ultra-high temperature application. The T2/Moss and (Mo,Nb)ss/T1/T2 eutectic alloys have been grown using an optical floating zone method. In this paper, their microstructure, fracture toughness at room temperature and strength at high temperatures are investigated.
