 note = {application/pdf, In this research, focusing on the vibrational energy (acoustic energy) of ultrasonic waves that can be generated with a relatively simple device, hot-press sintering of Ni metal powder under assisting this energy is examined to improve sintering promotion and the strength by an experiment. A pure Ni metal powder is packed in a cylindrical mold, then, heated to a hot-press temperature in inert Ar gas. The hot pressing at 40 MPa under ultrasonic vibration (using ultrasonic transducer with inherent frequency of 20 kHz and 28 kHz) was applied to the metal powder for a predetermined sintering time. The relative density, tensile strength and electrical conductivity of the sintered compact were investigated. As a result, it is able to promote sintering and increase the strength by the aid of the ultrasonic waves.},
