In this paper, the effect of Ti content and the number of training cycles on the shape memory behavior of TiNi alloys were investigated. For this purpose, four ingots with different composition were caste in VIM furnace and then hot-rolled and annealed. After the investigation of the shape memory effect, in order to study the two-way shape memory effect, all samples were trained in martens tic state. The results show that with increasing Ti content, shape memory effect reduces. Also, it can be seen that with increasing the number of training cycles, two-way shape memory effect increases.
