Studies of Al-Ti alloys by SEM

Abstract

Al-Ti (1, 2 wt. %) alloys were investigated by Scanning Electron Microscopy (SEM). SEM observations and energy-dispersive x-ray analyses (EDX) showed that the phase structure of Al-Ti (1 %) alloy at 165 ?m/s is composed of Al matrix and C, Ni, Fe and Si particles and the Al-Ti (1 %) alloys at 16 and 8 ?m/s have only the Al matrix and C particles, It was also found that the Al-Ti (2 %) form the Al matrix and intermetallic TiAl. © 2007 American Institute of Physics.
