High temperature shape memory alloy thin film

A magnetron sputter deposition process for producing a thin film alloy exhibiting shape memory characteristics comprising conducting the sputter deposition using krypton as process gas, depositing the alloy onto heated substrate so secondary annealing is unnecessary, and using a sputter target titan...

Beschreibung
Zusammenfassung:	A magnetron sputter deposition process for producing a thin film alloy exhibiting shape memory characteristics comprising conducting the sputter deposition using krypton as process gas, depositing the alloy onto heated substrate so secondary annealing is unnecessary, and using a sputter target titanium, nickel and/or palladium in proportions so as to produce a thin film alloy of a composition having a titanium content ranging from at least about 50 atomic percent to less than about 52 atomic percent.
