Mechanical Behavior of Porous Ni-Ti Alloy Produced by Bulk Combustion Synthesis Method for Bone Surgery

Mechanical property of porous nickel-titanium alloy produced by volumetric combustion synthesis (VCS) for bone surgery applications is reported in this paper. Stress-strain behavior of the alloy is determined by uniaxial tension test. Superelastic diagram of the porous alloy is compared with that of...
