Abstract
Explored was the extraction of target TiAl powder from SHS-produced TiAl–MgO semiproduct by treatment in acids (H2SO4, HCl,) and NH4Cl solution. Acid leaching was found to be accompanied by marked elution of target TiAl: the yield of TiAl powder was 21 and 33% in case of leaching with H2SO4 and HCl, respectively. But upon leaching with enriched NH4Cl solution at 70–80°C for 30 min, the yield of purified TiAl powder attained a value of 60%.
