|Abstract||The influence of Mo addition on the microstructure and properties of TiNiNb alloy with 4.5 at.% Nb has been investigated systemically. The experimental results indicated that the uniform distribution of Mo depresses the appearance of coarse beta-Nb particles at the grain boundaries and short stripped texture consisting of abundant fine disperse Nb-rich particles appears around the grain boundaries. The yield strength of the alloy was enhanced from 450 to 600 MPa due to the solution strengthening of Nb and Mo and the elongation reached 18% when the Mo content is 0.5 at.%. At the same time, the shape memory effect of the alloy also is improved significantly by the Mo addition. The maximum recoverable strain of the alloy with 0.5 at.% Mo is near 8% and has reached the high level of Ni-Ti binary alloys. This novel high-strength alloy is promising to be used for high pressure tube and the macro-scale coupling with higher-quality requirements.|
