Contrasting Effects of Laser Shock Peening on Austenite and Martensite Phase Distribution and Hardness of Nitinol
Laser shock peening of cold rolled Nitinol was carried out at high power density (7 and 9 GW/cm<sup>2</sup>) and high overlap ratio (90%). Tensile surface residual stresses were generated in the peened material. An enhancement in surface microhardness from 351 for unpeened material to 37...
