Modelling human social behaviour in conflict environments using complex adaptive systems
2008
A high melting point and/or low ductility metal or alloy is investment cast in a refractory mold including a facecoat layer and a plurality of back-up layers wherein at least one back-up layer is a relatively weak, sacrificial layer. This latter layer is crushed as necessary as the casting cools below its ductile-to-brittle transition temperature to avoid hot tearing or cracking of the solidified metal or alloy during cooling in the mold.
