Abstract
Composite powder particles which are essentially spherical in shape are disclosed which consist essentially of particles of a matrix phase which consists essentially of a metal selected from the group consisting of aluminum and aluminum based alloys and a reinforcement phase which is relatively uniformly dispersed in and bonded to the matrix, the reinforcement phase comprising titanium diboride. A process is disclosed for producing the above composite particles which involves entraining in a carrier gas a plurality of agglomerated powders, at least one of the powders supplying aluminum, at least one of the powders supplying titanium without boron and at least one of the powders supplying boron without titanium. The powders are fed through a high temperature zone to cause essentially complete melting and coalescence of the powders wherein at least a part of the titanium and at least a part of the boron combine to form titanium diboride and thereafter resolidified to form the composite powder particles. The resolidification can be done by impacting the high temperature treated powder against a surface having a temperature below the solidification temperature of the matrix, in which case a composite material is formed.
