Statistical analysis for cost effective process parameters and localized strain hardening behavior of Al-7050 foam

摘要

Cost effective process parameters of fabricating Al-7050 foam were obtained by reducing amount of blowing agent and processing time in advancement of low cost, low density and high mechanical properties for structural applications. Quasi-static compressive properties and localized plateau deformation behavior were studied. Maximum strength to density ratio up to 40.38 MPa/(gm/cm(3)) with utilizing 0.2 wt% TiH2 was achieved. Localized brittleness of plateau cell walls were observed by localized strain hardening behavior in plateau deformation. (C) 2021 Elsevier B.V. All rights reserved.
