Conditions for SHS of intermetallic compounds with selective laser sintering of powdered compositions

The selective laser sintering of powdered mixtures traditionally used in hi gh-temperature synthesis technology is studied. It is shown that a controll ed exothermic combustion reaction can be set up in the focal spot of a CW N d-YAG laser. The required laser interaction parameters (power, scan rate, a nd laser beam diameter) and dispersity and composition of the powder compos ition are determined for this mode of preparing three dimensional samples o f intermetallic compounds by selective laser sintering.
