Problems solved by technology

However, unlike plastic deformation due to dislocation motion and thus irreversible, deformation of martensitic SMA via detwinning mechanism does not involve dislocation motion or breaking of internal atomic bonds

Abstract

The present invention relates to a thermally-activated material assembly converting between a actuation condition and a non-actuation condition. The assembly comprises an actuator material for enabling an actuator component to actuate from a non-actuation shape to an actuation shape responding to being heated or cooled to be higher or lower than an actuation temperature, and vice versa. The assembly has a phase-change material (PCM) connected with the drive mechanism of the actuator component and connected with the drive mechanism. The drive mechanism enables the PCM to be directly jointed with the actuator component when the actuator assembly is in the non-actuation condition and to be separated from the actuator component when the actuator assembly is in the actuation assembly (i), or enables the PCM to be directly jointed with the actuator component when the actuator assembly is in the actuation condition and to be separated from the actuator component when the actuator assembly is in the non-actuation assembly element (ii).

Description

[0001] related application [0002] This patent application claims U.S. Patent Application No. 12 / 792,120 and 2009, filed June 3, 2010, entitled "ACCELERATING COOLING IN ACTIVE MATERIAL ACTUATORS USING HEAT SINKS" Priority to U.S. Patent Application No. 12 / 437,768, entitled "CONTROLLING HEAT TRANSFER IN ACTIVE MATERIAL ACTUATORS USING HEAT SINKS," filed May 8, and is a continuation in part thereof, the entire contents of which are hereby incorporated by reference. Background technique [0003] The present invention relates generally to thermal management of thermally activated active material assemblies, and more particularly to thermal management of thermally activated active material assemblies using phase change materials. [0004] background [0005] I. Shape memory alloy [0006] Shape memory alloys (SMAs) are the generic name given to alloys that exhibit the rare property of strain memory that can be induced mechanically or thermally. This rare property is mainly ch...
