Enhanced internal friction and specific strength of porous TiNi shape memory alloy composite by the synergistic effect of pore and Ti2Ni

The contradictory relationship between the damping capacity and specific strength remains a challenge for developing metallic damping materials with high strength and stability for energy-absorbing and energy-saving applications. Porous TiNi shape memory alloy composite (SMAC) seems to be a valid strategy to solve this problem. The deformation and damping behaviors of porous SMAC (composed on a particle-like brittle Ti2Ni embedded in ductile...
