Paper Title:
Structure and Properties of MASHS Titanium Aluminide–Based Powder Alloyed with Chromium
  Abstract

Structure and properties of MASHS powder Ti-46Al-8Cr, at. %, have been investigated. The powder is characterized by the multiphase dispersed strengthened structure with coherent precipitates/matrix bonding. Main structural constituents of the powder are titanium aluminides alloyed with chromium: γ-TiAl(Cr), Al0,67Cr0,08Ti0,25 and α2-Ti3Al(Cr). Average powder microhardness is 313 HV0.25. High-quality detonation coatings with high hardness (940-1100 HV) and low porosity (less than 1%) have been obtained from the synthesized powder. The coatings exhibit good oxidation behaviour at 900°C.
