Shape Memory Alloy Adaptive Structures, Phase I

This SBIR Phase I effort will demonstrate and scale up an innovative manufacturing process that yields aerospace grade shape memory alloy (SMA) solids and periodic cellular structures. Bulk-sized SMA components and structures are extremely difficult to fabricate as castings due to the compositional sensitivity of these alloys. Remelting also leads to brittleness from the presence of deleterious phases and precipitates that form upon metal solidification. For cost effectiveness, structural integrity, and shape memory and/or superelastic behavior, SMA castings with the requisite composition-microstructure-properties are needed and will be developed in this work.
