Solid-State Processing Route, Mechanical Behaviour, and Oxidation Resistance of TiAl Alloys

Superplastic behaviour and mechanical properties of two phase TiAl alloys

High temperature plastic flow properties of two phase TiAl alloys containing 45 to 49 at.%Al have been investigated in thermo-mechanically grain refined materials in order to clarify the favourable microstructure and chemical composition for TiAl based superplastic materials. Grain sizes of thermomechanical treated materials and their grain size stability during subsequent high temperature defo...

Isothermal and cyclic oxidation of TiAl composites

Titanium Aluminide and TiAl matrix composites reinforced with alumina fibers (PRD166) were fabricated by powder metallurgy. During isothermal oxidation at 950 and 1070 OC, composites containing PRD166 fibers exhibited larger weight gains than monolithic TiAI; the composites showed evidence of oxidation along the perimeter of the fibers. A fiber reaction, which was observed after oxidation in ai...

Synthesis and Processing of SnO2, CaSnO3 and Ca2SnO4 Nanopowders by Solid-State Reaction Technique

The nanopowders of SnO2, CaSnO3 and Ca2SnO4 in the size rang of 5-70 nm have been prepared using solid-state reaction technique. The technique is convenient and inexpensive in comparison to the conventional routes of compound prepared and processing where, many steps of mixing and annealing are i...
