Abstract: The microstructure of x-Ti/ mild steel composite fabricated by using constant stand-off cladding technique was observed with optical microscopy, SEM and TEM analyses. Very fine equiaxed grains (<0.1um) with a low dislocation density were observed in the adiabatic shear bands (ASB) this enables a thermomechanical response that may lead to a super plastic de formation.

Key words: a-titanium, super plastic behaviour, strain rate, adiabatic shear band
