Abstract
Hot isostatic pressing, HIPing, is applied for Al-Mg foils. However, delamination is a major limitation, an emerging methodology is introduced. Toughening mechanisms is an objective. Parametric study established for the control of interface/interphase kinetics. Micro-plasticity induced the formation of metal flow along with interfacial bonding. Low melting depressant (LMD), Zn, and alloying element segregation tends to form micro laminated and/or nano structure interphase in a lamellar composite solid state processing. Microstructural characterization, mechanical characterization is also established via optical microscopy scanning electron microscopy, energy dispersive X-ray spectroscopy and tensile testing. Chemical and mechanical bonding via inter diffusion processing with alloy segregation are dominant for interphase kinetics. Mechanical characterization with interfacial shear strength is also introduced. HIPing processing is successfully applied on 6082 Al-alloy and AZ31 magnesium alloy for either particulate or micro-laminated interfacial composite processing. The interphase kinetic established through localized micro plasticity, metal flow, alloy segregation and delocalized Al oxide and Mg oxide.
