Introduction: In the Ti-Al diffusion system, intermetallic formation is reasonable to be controlled by diffusions of the titanium and aluminum through the compound layer. The current understanding of diffusion process in ...

Diffusion bonding of elemental titanium and aluminum foils is an effective low-temperature method to synthesize the intermetallic-metal composite, allowing growth of the intermetallic layer while both reactant materials ...

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 ...

Titanium–aluminum diffusion couples were prepared using pure titanium and aluminum sheets in the form of a tri-layer sandwich. The Ti–Al interface was investigated after heating the specimens at 550, 575, 600, 625, 640 and ...

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 ...
