Ti-6Al-4V 0.5" plates were rolled from 2.75" x 8" x 30" slabs made by PAM single melting of Armstrong powders. Armstrong powders were mixed with Al-V master alloy powders to form the Ti-6Al-4V chemistry. The mixture of these powders were then pressed to 2 lb weight compacts which were used as the input material for PAM processing. Rolled plates were heat treated and evaluated for microstructure, mechanical properties, weldability and ballistic property.

Powders produced by ITP's Armstrong Process can be used as a sponge replacement for the conventional melt processing as well as input material for the powder metallurgy non-melt processing.  This presentation provides a summary of the process and results conducted at RTI and Concurrent Technologies Corporation (CTC) and funded by the US Army in using ITP powder in manufacturing plate from cast slabs produced from plasma melting of the powder.
