Abstract

합성과 동시에 소결이 이루어지는 HPCS법을 이용하여 TiB$_2$-W 복합체를 텅스텐의 함량 변화에 다라 제조하여 이 복합체의 미세구조 및 기계적 물성에 대하여 연구하였다. 이 연구 결과, 텅스텐의 함량증가에 따라 삼성분 붕화 화합물인 TiWB$_2$의 상이 증가하였으며, 이 상의 증가에 따라 기계적 물성이 향상되었다. 60 MPa의 압력과 130$0^{\circ}C$, 3000 A에서 소결한 TiB$_2$-30vol% W 복합체에서 상대밀도, 강도, 경도 값은 각각 97.2%, 411.5 MPa, 22.36 GPa로 가장 우수한 물성을 얻을 수 있었다.
