Determination of Relation between Elastic Constant and Sintered Temperature in WC-Ni Composites
In this study we have investigated relation between elastic constant and sintered temperature in tungsten carbide- nickel composite samples. Determination of elastic properties of materials is based on the transverse and longitudinal waves velocities via ultrasonic methods. In this study ultrasonic velocity measurements were measured in the WC-Ni composites. These samples are formed by powder metallurgy and electroless plating. Samples were sintered at temperatures of 1000?C, 1100?C, 1200?C and 1300?C with Ar gas atmosphere in tube furnace. In the measuring ultrasonic longitudinal velocity 2 and 5 MHz transducers, ultrasonic transverse velocity 1 and 5MHz transducers have been used. Young Modulus (E) has been calculated by using longitudinal and transverse velocity. After we calculated elastic constant, we have investigated relation between sintered temperature and elastic constant of samples. A linear relation between sintered temperature and elastic constant in samples is observed.
