Physical metallurgy of magnesium

Abstract

Key features in the deformation behaviour of magnesium have been introduced in terms of the consequences of hexagonal crystal structure, dislocation core width and stacking fault (SF) energy concepts. Elastic and plastic deformation behaviour of magnesium has been addressed in relation to critical resolved shear stress, slip and twinning. The anomalies during plastic deformation, fatigue, creep, recrystallization and grain growth in magnesium and its alloys have been pointed out and discussed under individual headings. Future trends in research and use of magnesium alloys have been indicated.
