Major casting processes Sand casting Investment casting Lost-foam casting Gravity die casting (permanent mould casting) Low pressure die casting High pressure die casting Centrifugal casting

Introduction Casting practice Design considering in casting Design for expendable-mold casting

第一节 聚合物的熔融 第二节 聚合物的溶解

Solidification of Peritectics • General considerations of pertitectics • Nucleation of peritectics • Solidification of peritectics Microstructure control through solidification method Solidification Defects The other defects

Solidification of Eutectics • Coupled eutectic growth morphology • Other eutectic morphologies

• Dendrite arm spacing • Formation of equiaxed grains • Cast microstructure

• Solidification microstructure: Cells and dendrites • Constrained growth • Preferred growth direction

• Application: Zone melting Morphology Instability of a S/L interface • Constitutional undercooling • Morphological instability of a S/L interface

• Solute redistribution in non-equilibrium state • Solute distribution in front of S/L interface
