摘要： INTERMETALLIC COMPOUNDS WHICH, UPON COOLING BELOW A CHARACTERISTIC TEMPERATURE TF, ARE SUBJECTED TO A SO-CALLED MARTENSITE CRYSTAL TRANSFROMATION TO A CRYSTAL STRUCTURE HAVING A CLOSER PACKING MAY BE USED AS SHAPED MEMORY ELEMENTS. SHAPE MEMORY ELEMENTS HAVE THE PROPERTY THAT, AFTER DEFORMATION AT A TEMPERATURE BELOW TF, THEY REASSUME THEIR ORIGINAL SHAPED BY HEATING ABOVE TF.
