Abstract
Abstract : NITINOL is an alloy of nickel and titanium which exhibits a shape memory effect. The term shape memory effect (SME) is used to describe the ability of certain alloys which, if deformed at a low temperature, will recover their prior shape when heated. A solid state sintering process has been successfully adapted to consolidating NITINOL alloy powders. NITINOL alloys are noted for their shape memory properties. The sintering process is performed at atmospheric pressure upon powders contained in an evacuated glass container. Processing parameters are reported. Tubes and tubular tees were made as well as solid round bars. Round bar stock was extruded and swaged. Excellent shape memory properties were obtained. Originator-supplied keywords include: NITINOL, Shape memory alloys, Consolidation, Powder metallurgy, CAP process, and Pipe fittings.
