dc.description.abstractThe computer aided design/computer aided manufacturing(CAD/CAM)method represents a great advancement over casting technology. However, the poor machinability of Ni-Cr alloy is an obstacle to practical dental application. In this study with the purpose is to develop Ni-Cr alloys for CAD/CAM containing Ta, Nb and Fe with superior properties than commercial products. In order to evaluate of the properties of Ni-Cr alloys containing various amount of Ta, Nt and Fe, tensile strength, hardness, thermal expansion coefficient, XRD analysis and machinability were investigated. X-ray diffraction patterns were noted that new precipitation of gamma prime phase was increased with the increasing Ta content. The tensile strength and micro-hardness were increased with increasing Ta content whereas Nb and Fe were not effective to enhance mechanical properties. High machinability was showed at proper hardness value of alloys, especially 225.8HV. From the above results, it is considered that 0.7wt% Ta, 3.2wt% Nb and 4.3wt% Fe containing Ni-Cr alloys could be able to use either casting or machining substrate.-
