| 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. |
