| ABSTRACT Hot Isostatic Pressing, HIPing, of 6082 Al-alloy and AZ31 magnesium alloy is applied in Al-Mg foil-foil technique symmetrical arranged. However, delamination is a major limitation of lamellar composite structure, an emerging methodology introduced with micro laminated and/or delocalized nano particulate interphase. Mitigation of crack as well as toughening mechanisms is an objective. Parametric study (temperature, pressure and holding time) established for the control of interface/interphase kinetics. HIPing parameters as well as alloying elements have a dominant effect on kinetic of formation interphase. Lamellar metal matrix composites introduced with new micro laminated composite interphase. Micro-plasticity induced the formation of metal flow along with interfacial bonding as well as, low melting depressant (LMD) Zn. LMD induced the localized interphase structure enriched with either Al or Mg. Alloying element segregation tends to form nano composite structure or micro laminated composite in a solid state processing. Parametric study has been prompted to redesign lamellar structure for the control of interphase and interface with no delamination and porosity. Microstructural characterization, mechanical characterization is also established via optical microscopy scanning electron microscopy, energy dispersive Xray spectroscopy and tensile testing. Chemical and mechanical bonding via inter diffusion processing with LMD are dominant for interphase kinetics. Mechanical characterization with interfacial shear strength is also introduced with hardness testing. HIPing processing is successfully applied on 6082 Al-alloy and AZ31 magnesium alloy for both particulate composite or micro-laminated composite processing. The interphase kinetic established through localized micro plasticity, metal flow, LMD and delocalized Al oxide and Mg oxide. The morphology of interphase is cached with interesting structures that need more studies. | ||
