Abstract
The work aims to study the effect of the Fe content on the properties of Ti50 Ni(50−X) Fe X alloy (where X = 0, 2, 4, 6, 8, and 10 at.-%) sintered at 1050°C and 1150°C using the conventional sintering technique. The microstructure, chemical composition and phase evolution of the sample were analysed by SEM, EDS, and XRD, respectively, along with various properties. It was observed that the sintered sample microstructure consists of (Ni, Fe)-rich, and Ti-rich phases. Here, the porosity decreases, whereas density, hardness, and wear resistance increase with the increasing temperature. The 8at.-%Fe sample shows lower porosity and higher wear resistance, relative density and hardness value than other Fe content samples. The 2at.-%Fe sample sintered at 1050°C shows a higher shape recovery value compared to other compositions sintered at various temperatures.
