A Self-Propagating Foaming Process of Porous Al-Ni Intermetallics Assisted by Combustion Reactions

The self-propagating foaming process of porous Al-Ni intermetallics was investigated. Aluminum and nickel powders were blended, and titanium and boron carbide powders were added as reactive exothermic agents. The blended powder was extruded to make a rod-shape precursor. Only one end of the rod prec...
