Abstract
In the present study, TiXMo5Cu alloys were produced utilizing the powder metallurgy technique. Alloy samples with different ratios of Mo added were shaped by uniaxial pressing under 550 MPa pressure. The shaped samples were subjected to a sintering process at 5 different temperatures for a waiting time of 180 min in a 99.99% pure argon gas atmosphere. The densities of the fabricated specimens were found with the Archimedes principle. Microstructures of the obtained samples were attained by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) examinations. For the determination of the mechanical characteristics, micro hardness and tensile tests were applied. According to the density measurements, the highest relative density values were attained with the sintering temperature of 1300 °C, and a higher Mo ratio resulted in a lower relative density. The microstructure of the fabricated specimens is comprised of α-Ti and β-Ti phases. The α-Ti phase ratio in the microstructure reduced based on rising Mo, while the ratio of the β-Ti phase increased. Accordingly, while the hardness values increased, the strength values decreased.
