Abstract
The thickness of flame zone reaction rate and apparent activation energy in the formation reaction of $Ti_3AI$ intermetallic compound were investigated using SHS method which sustains the reaction spontaneously and utilizes the heat generated by thye exothermic reaction itself. In this reaction the thickness of flame zone was 1.4 mm and the reaction rate was $0.4g/\textrm{cm}^2{\cdot}sec$. Also the apparent activation energy calculated using from the experimental data obtained by controlling the realtive green density was 40kJ/mol.
자체의 반응열에 의해 반응이 자발적으로 진행되는 SHS법을 이용하여 $Ti_3AI$ 금속간 화합물의 생성반응에서의 화염대 두계, 반응속도 그리고 겉보기 활성화에너지에 대하여 고찰하였다. 이 반응에서 화염대 두께는 1.4mm이었고, 반응속도는 $0.4g/\textrm{cm}^2{\cdot}sec$이었다. 또한, 반응물의 상대밀도를 조절하여 얻은 실험 data를 이용하여 구한 반응의 겉보기 활성화에너지는 40kJ/mol이었다.
