Abstract

Graphical abstract: Abstract : The analytic modeling and one experimental assess of the ultrasonic surface mechanical attrition treatment are presented. The bombarding ball speed, induced energy, hardness and grain size are incorporated into this model, based on harmonic longitudinal vibration motion of ultrasonic-wave-driven impact. There appear some optimum attrition working parameters for the best attrition effect; beyond which, the sample surface would be subject to bombarding microcracking and the grain size would not be further reduced. The benefits from attrition would become lower.
