Compressive Behavior for Surface-Nanocrystallized Al-Alloy Material

Abstract

Mechanical behavior of surface/nanocrystallized material fabricated by the ultrasonic shot peening method is investigated experimentally and theoretically. In the experimental research based on microscopic observations the compressive specimens are designed and machined considering the material features, and the compressive experiments are performed. Furthermore the compressive stress-strain curves are measured in the theoretical research a microstructure cell model is presented considering the material microscopic organization observed from experiments and the compressive stress-strain relations are simulated. Both experimental and theoretical results display the strong size effect on the material behavior.
