Abstract
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.
