Understanding precipitation processes in magnesium alloys

Abstract

Recent interest in developing high strength wrought magnesium alloys has revived studies of precipitation processes in magnesium alloys, as they can be used to control recrystallized microstructure and to add yield strength by age hardening after processing of wrought magnesium. In this chapter, we describe the basic information necessary for controlling precipitate microstructures by aging. Thereafter, precipitation processes and microalloying effects in representative age-hardenable magnesium alloys are reviewed.
