非晶态粉末制备的Al-4.0Y-4.0Ni-0.9Co超细晶挤压合金具有高强度、低塑性的特点。对挤压态材料进行热轧可提高其延展性。讨论了影响挤压和热轧材料塑性的因素。
As-extruded ultrafine-grained Al–4.0Y–4.0Ni–0.9Co alloy produced by amorphous powders exhibited high strength but low ductility. Hot rolling of the as-extruded material resulted in enhancement in ductility. Factors affecting the ductility in the as-extruded and hot-rolled materials are discussed.
