Abstract

The effect of the Ti content on polycrystalline microstructure, phase transformation behavior, mechanical behavior and magnetic properties of the Ni₅₃Mn_23.5Ga_23.5-xTi_x (x = 0, 0.5, 2, 3.5, 8, 15, at%) ferromagnetic shape memory alloy was studied by means of OM, DSC, room temperature compression tests and ac susceptibility measurements. The results show that the solubility limit of Ti element in the alloys is below 15%. The transformation temperature, the fracture strength and the fracture strain increase at first and then decrease with increasing of the Ti content. Furthermore, it is concluded that Ti addition can change the fracture type of Ni₅₃Mn_23.5Ga_23.5-xTi_x alloys from the intergranular fracture to the transgranular to the intergranular again. In addition, the Curie temperature decreases gradually with the increase of Ti content in Ni₅₃Mn_23.5Ga_23.5-xTi_x alloys.
