Tape Casting of Copper Based Shape-Memory Alloys

摘要

The fabrication of Cu-AI-Ni-Mn alloys by tape casting followed by hot-compaction has been investigated. A slurry composed of a mixture of metallic powder, solid lubricant, binder, plasticizer and solvents has been used. Dense and chemically homogeneous Cu-AI-Ni-Mn shape-memory alloys have been obtained. The microstructure of the sintered compacts has been studied by scanning electron microscopy. The shape-memory effect has been demonstrated in bending.
