New Type Spherical Pores Al Foam and its Properties

Abstract:

Article Preview

Based on compression curves of spherical pores Al foam measured, compressive yield strength, the densification starting pointand energy absorption had been investigated. The compressive stress-strain curve of spherical pores Al foam consists of three distinct regions, i.e., the linear elasticity region, yield platform stage and the densification region. The way to determine the densification starting pointεD of high density metal foam has been presented. Spherical pores Al foam is a cellular metal material of high plastic performance, so energy absorption capability of it is bigger than that of spherical pores Al alloy foam. Compressive yield stress was in good agreement with Gibson-Ashby model’s expectation.
