Effect of Mo on mechanical properties and microstructure of Nb–Ti–C alloys

The microstructures and mechanical properties of Nb–Ti–C alloys containing different Mo contents have been investigated. The alloy without Mo contains Nb solid solution (Nbss), (Ti,Nb) 2C/β(Nbss) eutectic, (Ti,Nb) 2C and (Ti,Nb)C. The addition of Mo restrains the precipitation of (Ti,Nb)C. Compressi...

Zusammenfassung:	The microstructures and mechanical properties of Nb–Ti–C alloys containing different Mo contents have been investigated. The alloy without Mo contains Nb solid solution (Nbss), (Ti,Nb) 2C/β(Nbss) eutectic, (Ti,Nb) 2C and (Ti,Nb)C. The addition of Mo restrains the precipitation of (Ti,Nb)C. Compression testing has been carried out at room temperature and 1473 K. The alloys showed good ductility at room temperature and Nb20Ti12.5C20Mo produced a 0.2% offset yield stress of 300 MPa at 1473 K. The room temperature and high temperature strengths increase with increasing Mo, but the addition of Mo decreases the room temperature ductility.
