| Abstract: | Powdered materials of alloyed Ni 3Si and Ni 3(Si,Ti 0.1 ) with low exothermic reaction behavior are prepared by means of combustion synthesis. The effect of ballmill duration, preheating temperatures, and macro alloying element Ti on the combustion synthesis is analyzed. The product's phases and morphology were analyzed by means of X ray diffraction meter(XRD) and scanning electron microscope(SEM). Experimental results show that all these mechanical activation, thermal activation, and addition of macro alloying element Ti can affect the combustion synthesis processing. |
