Abstract

The influences of Mo on the phase transformation, microstructure and mechanical behavior of TiNi(Fe) shape memory alloy are investigated by differential scanning calorimetry, X-ray diffraction, and tensile stress-strain measurements. The results show that the lattice parameter of TiNi(Fe,Mo) increases with progressing replacement of Ni by Mo, while the martensitic transformation characteristic temperatures decrease simultaneously. The yield strength of TiNi(Fe) alloys has been remarkably improved by addition of Mo, e.g. Ti₅₀Ni₄₇Fe₂Mo₁ alloy (at.%) shows a yield strength of 400 MPa, which is 33% higher than that of Ti₅₀Ni₄₈Fe₂. Moreover, the martensite reorientation stress of Ti₅₀Ni₄₇Fe₂Mo₁ is 250 MPa at liquid nitrogen temperature and a shape memory effect of 6.4% has been achieved.
