High Plasticity Magnesium Alloys focuses on the microstructure, mechanical properties and processing methods of magnesium alloy materials. The title offers theory and methods on high-plasticity magnesium alloys, including phase diagram construction, alloying and deformation. Four typical high-plasticity magnesium alloys are discussed through thermodynamic phase diagram construction and the characterization of their microstructure, mechanical properties and texture at as-cast, extruded, rolled and heat-treated states. Chapters update principle calculations for the effects of alloying elements, Mg-Gd-Zr medium strength and high-plasticity alloys, medium strength and high-plasticity Mg-Mn based alloys, medium strength and high-plasticity Mc-Sn based alloys, and Mg-Gd-Y-Zn-Mn high-strength and high-plasticity magnesium alloys.

This book presents the plasticity of magnesium alloys, and guides the design and development of new high-strength and high-plasticity magnesium alloys. It provides detailed solutions for practicing industrial engineers.
