The general topological model for interfacial defects is reviewed and expanded, and the role
of these defects in the coupled shear-migration of interfaces is explored. We focus on …

The physical basis for the Frank–Bilby equation is considered. Dual descriptions in terms of
interface physics and mechanics are introduced. Natural (NDP), commensurate (CDP) and …

High-entropy alloys (HEA) and medium-entropy alloys (MEA), containing multiple principal
elements typically with equiatomic or near-equiatomic ratios, have drawn considerable …

Expanded and revised to cover developments in the field over the past 17 years, and now
reprinted to correct errors in the prior printing, Phase Transformation in Metals and Alloys …

The second edition of this textbook, popular amongst students and faculty alike, investigates
the various causes of thermodynamic instability in metallic microstructures. Materials …

The microstructure of a nanocrystalline Mg97Zn1Y2 (at%) bulk alloy prepared by warm
extrusion of rapidly solidified powders has been investigated by a combination of …

Strengthening precipitate phases in a Mg–Y–Nd based alloy (WE54), aged at 250° C, have
been characterised using transmission electron microscopy. Precipitation at 250° C involves …

Twins and 9R phase (a structure containing a high density of stacking faults) have played
important roles in simultaneously improving strength and strain hardening capacity of low-to …

Interfacial defects may exhibit both dislocation and step-like character. The Burgers vector of
such a defect is an invariant topological quantity which can be determined mathematically or …

Solute segregation and the precipitate phases in a creep-resistant Mg–1Gd–0.4 Zn–0.2 Zr
(at.%) alloy aged isothermally at 250 and 200° C have been examined using a three …
