This letter reports a new strain glass, Ti-19Nb-9Zr-1Mo, exhibiting a combination of good superelasticity of ∼3.1% strain after unloading from ∼3.5% strain and complete shape memory effect at room temperature. An effect of doping point defect with Mo suppresses the formation of long range strain order's martensites. This doping effect leads to the formation of nanodomains with α″ martensites in microstructure. The superelasticity relates to a random distributed point defect which opposes to the formation of favorable single variant in the alloy. © 2013 The Authors.
