Microstructures and properties of ultrasonically surface-modified Cu–0.2Be–1.0Co alloy

Jinyun Wang,

Abstract: Low-Be copper alloys exhibit high thermal and electrical conductivities but weak strength, hardness, wear and corrosion resistances, which limit their practical applications severely. To overcome these defects, we herein systematically investigate the effects of ultrasonic surface modification on the microstructures and properties of Cu-0.2Be-1.0Co alloy. It is found that the gradient microstructures characterized by pile-ups and dents, fine grains, dense dislocations and compressive residual stresses are gene… Show more
