초록

기계적합금법으로 Ti와 B의 혼합분말로부터 TiB 2 분말을 제조하였고, Zr과 Ta의 Ti 치환 효과를 조사하였다. (Ti+B)의 혼합분말을 280시간 분쇄하여 TiB 2 단일상을 얻었고 기계적합금화 도중 비정질상은 관찰되지 않았다. Ti의 일부를 원자반경이 Ti보다 큰 Zr으로 치환한 결과 기계적합금화에 걸리는 시간이 크게 감소한 반면에, 붕화물 생성열이 절대값이 TiB 2 상보다 작은 Ta로 치환하면 280시간 분쇄하여도 단일상을 형성하지 못하였다.

TiB 2 powders were prepared by mechanical alloying, and the effect of Zr and Ta substitution for Ti was investigated. It was possible to produce titanium diboride phase by mechanical alloying titanium and boron elemental powders for 280 hours. The amorphization reaction, a common process which occurs during mechanical alloying, has not been found. When zirconium of which atomic radius was larger than that of titanium was substituted for Ti, the alloying time was greatly reduced. On the contrary, substitution of tantalum for titanium prolonged the alloying time because of the less negative heat of formation of tantalum diboride than that of titanium diboride.
