Two phases dominate the performance of commercial Mg alloys: (1) β Mg17Al12 and (2) porosity. Alloy design and process design to optimize the morphology of the first and to minimize the second are discussed. Second phase β can be designed to improv

A wide variety of Mg alloys have been processed by Thixomolding ® followed by thermomechanical processing (TMP)—to increase tensile, creep and fatigue strength, ductility and formability. These alloys encompass variations in Al, Zn, Ca, Mn, Sr, Y,

Thixomolding of Mg alloys produces fine microstructure of about 5-10 micron alpha phase grain size, surrounded by divorced eutectic phases. During the period from 1995 to 2009, this process and microstructure has captured broad applications around th

Commercial Mg alloys, compared to other engineering materials such as steels or aluminum materials have inferior strengths (Y.S. = ~120 MPa), limited ductility and poor formability. Furthermore, due to high costs their use in structural applications

A new procedure for blending die-cast Mg−Al alloys by semisolid processing to achieve controlled variations in microstructure and properties has been investigated. Granules of AM6-B and AZ91D have been blended in varying proportions and Thixomolded

The discovery of y' hardening early in the 20th century seeded a continuous evolution of a remarkable family of alloys, known as the superalloys. The sequence of their development will be traced in this article. The theories of alloying and hardening

Formability in magnesium alloy sheet is strongly limited by a strong basal texture in the as-rolled material, which is difficulty to remove by thermal processing. We introduce a new process to the control of texture by combining Thixomolding and Ther
