摘要

After a two-step heat treatment, the Cr₂Nb particles in a directionally solidified Nb-24Ti-12Si-10Cr-2Al-2Hf (at pct, unless stated otherwise) alloy were substantially refined into nanoscale precipitates. These precipitates showed the following orientation relationship with the Nb_SS matrix: (111)_Nb//(111)_Cr2Nb, [110]_Nb//[220]_Cr2Nb. The formation of nanoscale Cr₂Nb particles via an aging heat treatment at 1273 K (1000 °C) improved the tensile strength to 950 MPa and reduced the alloy weight gain from 218.27 to 144.41 mg/cm².
