Abstract
This article presents preliminary results of the processing and characterization of gamma-TiAl alloy modified by W addition. An alloy with the target chemical composition of TiAl-5W (at.%) was synthesized by mechanical alloying. Two methods were used for powder compaction: hot pressing at 1300 degrees C and hot extrusion at 1100 degrees C. Hot extrusion turned out to be a superior consolidation technique over hot pressing. The matrix of final alloy was composed of a phase based on TiAl and a minor amount of Ti3Al. The grain size in the extruded alloy was much smaller than in the hot-pressed one. Minute W particles formed a dispersoid.
