) are in the solid state. Reported data on mechanism and kinetics of the intermetallic layer growth such as kinetic exponent and activation energy vary widely among different works. In the current work, a simple diffusion couple of titanium and aluminum was prepared...

1. Introduction: Few studies have formerly focused on mechanism and kinetics of Ti-Al diffusion couples and the reported kinetic exponents and activation energies vary widely among different works. In this work, a simple diffusion couple of titanium...

widely among different works, which has made the phenomena more complicated.

Experimental Procedure: A simple diffusion couple was prepared by using one pure aluminum foil and two pure titanium sheets in a form of tri-layer sandwich held by a...

Pure titanium and aluminum sheets were used to prepare titanium-aluminum diffusion couples. The diffusion couples were heated to temperatures 550, 575, 600, 625, 640, 650 and 700°C. SEM observations of the titanium-aluminum interface and EPMA...
