This volume addresses progress in the application of solidification principles to the production of aluminum alloys. Topics include microstructure evolution, phase formation and solidification path analysis, grain refinement, micro/macro-segregation, mechanical behavior/properties in the mushy state, solidification cracking/tearing, gas/shrinkage porosity formation, effect of impurities/trace elements, and the impact of cast structure on the subsequent fabrication and properties of finished products. Papers on the experimental or theoretical simulation of solidification aspects of casting processes including direct chill casting, continuous casting, shaped casting, semi-solid processing, and other advanced casting technologies are also included, as well as examples showing the use of solidification principles to solve industrial problems.
