On precipitation hardening behaviour in a triaxial forged Mg-2Zn-2Gd alloy and relationship to mechanical properties

ABSTRACT Currently, there is a significant interest in magnesium (Mg) alloys for structural and functional applications. Mg alloys are lightweight materials (1.7–2.0 g/cm3), whose density is significantly lesser than that of titanium alloys and stainless steels. Furthermore, from the perspective of biomedical devices, they are biodegradable, bioresorbable and biocompatible. The objective of this work is to investigate the transition from grain boundary precipitation behaviour in the as-cast alloy to nanoscale precipitation during triaxial forging, with particular emphasis on exploring the application of small-angle X-ray scattering technique to investigate nanoscale precipitation and complement with the conventional approach of X-ray diffraction and electron microscopy.

期刊介绍： Materials Technology: Advanced Performance Materials provides an international medium for the communication of progress in the field of functional materials (advanced materials in which composition, structure and surface are functionalised to confer specific, applications-oriented properties). The focus is on materials for biomedical, electronic, photonic and energy applications. Contributions should address the physical, chemical, or engineering sciences that underpin the design and application of these materials. The scientific and engineering aspects may include processing and structural characterisation from the micro- to nanoscale to achieve specific functionality.
