AlTi porous bodies for use as structural materials are produced by Self-propagating High-temperature Synthesis (SHS). Initial Al and Ti POWDERS were first mixed and then cold pressed into preformed specimens. The specimens were then subjected to SHS by heating at the rate of 500ºC /min. In this research the compaction pressure was chosen as the main variable. For all specimens, relative density, bending strength and electrical conductivity was measured. Also Phase composition and morphology was determined by XRD and SEM. Results indicated that various Al-ATi binary compounds could be produced by SHS. Porosity decreased and pore size increased by increasing the compaction pressure. Electrical conductivity is found to be a good measure of porosity within the specimens. Bending strength increased considerably by increasing the initial compaction pressure of the pressed samples.
