Microstructure investigation of Al-rich titanium aluminum alloys

David Pham, University of Texas at El Paso

Abstract

The microstructures of Ti-Al alloys with 70-80 wt% Al were investigated. Aluminum wire (99.999%) and TiH2 powder (99.7%) were used to produce the sample compositions inside a vertical tube furnace at 1600°C in an Ar atmosphere. Argon is purified through a dehumidification and deoxidation system. Magnesium perchlorate Mg(ClO4)2 acts as a desiccant and titanium sponge pulls oxygen from the Ar in furnaces operating at 800°C and 750°C. X-ray diffraction and an optical microscope are used to identify phases and compositions.^
