Rheological behaviour of the mushy zone and its effect on the formation of casting defects during solidification

Correlating the microstructure and tensile properties of a thixomolded AZ91D magnesium alloy

Mechanical behavior of alloys with equiaxed microstructure in the semisolid state at high solid content

Three of the methods used to determine the volume fraction of solid as a function of temperature in alloys in the semisolid state, namely utilization of thermodynamic data, thermal analysis, and quantitative metallography on quenched microstructures, are studied. The accuracy of each method is evaluated and the advantages and limitations are recognized. It is demonstrated that, while all methods are approximate, they offer distinct and different advantages.
