| Abstract: | The effect of a hot extrusion regime for workpieces produced by calcium hydride reduction (CHR) of mechanically activated powders of an NiAl intermetallic alloy and an NiAl-Y2O3 alloy composite on their deformability is studied to form various (round, flat, lens-shaped) sections. The extrusion regimes that make it possible to produce defect-free samples of the NiAl-Y2O3 alloy composite with a metal-deformed structure without traces of dynamic recrystallization are developed. Deformed semifinished samples are formed. |
