A speedy and economical test method for determining the potential of metal powders to achieve desired mechanical properties after consolidation is described. It consists of encapsulating metal powders in an evacuated metal tube and reducing the outside diameter of the powder-filled tube by swaging to produce a fully consolidated powder bar which provides material for tensile testing. The tensile test results measure the potential of the metal powders. Application of the method to an evaluation of spherical (REP) and angular (H/DH) titanium alloy (Ti-6Al-2Sn-4Zr-6Mo) metal powders demonstrates the procedure can also be utilized to determine processing properties of metal powders. Results show both spherical and angular powders upon complete consolidation furnish tensile properties equivalent to conventional wrought Ti-6246 material. Results also indicate that the hydride powders (1.9% hydrogen) are less apt to be contaminated during processing. The test method is recommended as an excellent tool for determining the potential of metal powders to achieve mechanical properties and for establishing optimum processing parameters for consolidation of metal powders.
