The effects of aging on the shape memory properties of [1 1 1] oriented Ni45.3Ti29.7Hf20Pd5 single crystals were investigated under compression. Thermal cycling under stress and superelasticity experiments were conducted after 3 h aging at 550 and 600 degrees C and were found to be dependent on aging condition. Reversible strain of up to 2.2% and a work output of 33 J cm(-3) were possible at an ultra-high stress level of 1500 MPa. (c) 2012 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved
