It was found that low solidification velocity and high thermal gradient at the bottom of melt pool and above the solid/liquid interface results in the presence of columnar dendrites . Likewise, an equiaxed microstructure was also developed from middle to top section of the composite and this due to high solidification velocity and low thermal gradient at the upper part of the melt pool.

Increased laser power and scanning speed significantly increased the diffraction peak of Ti and Ti3Al. It is noted that Al and Ti concentration is highest which leads to the formation of titanium aluminide (Ti3Al) and presence of and phases.
