Spark-Plasma Sintering of TiNi Powder Produced by Mechanical Alloying
Abstract
기계적합금화법(MA)에 의해 제조된 TiNi 분말을 사용하여 방전플라즈마 소결법(SPS)으로 소결체를 제조하고 치밀화 거동을 조사하기 위하여 미세조직의 관찰 및 상분석을 행하였다. SPS법으로 소결체를 제조한 결과, 통상적인 소결법으로 소결체를 제조하였을 때 보다, 낮은 온도와 짧은 시간의 유지시간에서 이론 밀도의 99% 가까운 소결체 밀도를 얻을 수 있었고, 소결체의 상은 B2구조의 cubic과 2차상으로 Ti₂Ni가 존재함을 확인하였다.
Mechanically-alloyed TiNi powders were densified by Spark-Plasma Sintering(SPS) method. The densififcation behavior was investigated throgh the microstructural observation, the phase analysis and the measurement of change in devsity, linear shrinkage and densification rate as a function of temperature.

Sintered body with close to 99% relative density was obtained at lower sintering temperature for shorter holding time in comparison to the conventional sintering methods. TiNi with B2 structure was confirmed as the major phase and Ti₂Ni as the second phase.
