The Effect of Composition on High-Energy Laser Beam Combustion Synthesis of Fe-Al Alloys

For Fe-Al powder compacts, using high-energy laser beam combustion synthesis preparation for Fe-Al alloy. The microstructure and properties were analysised by X-ray diffractometer, optical microscopy and abrasive wear testing machine. The result indicated that synthetic products deviate from the equilibrium state of the intermediate phase and Al-rich phase produced; With the increase of aluminum content, the content of Al-rich phase increase, raising the level of the sample density; With the increase of aluminum content,morphology from fine acicular,strip noticeable,flake lath to massive growth; Synthesis of Fe-70at% sample of its uniform and a high densification, it has excellent wear and corrosion resistance.
