Exploring the self-healing capability in a metallic system, an experimental study was carried out for AA2014 and Nitinolbased smart composites material. The damage produced through the fexural test was healed by thermal heat treatmentthrough compositional healing. The objective of this work is to enhance the recovery in self-healing assessment throughdiferent hardening processes. Strengthening model (solution hardening and age hardening) as a strength enhancement isemployed on the healed samples (i.e. after heat treatment) to evaluate its efect and impact on diferent healing assessments. Further, XRD analysis was performed to explain how the developed residual stress in the microstructure is responsible inafecting the healing characteristics after each heat treatment processes. The obtained result show about 81.66% recovery incrack depth, 23.92% recovery in ductility, 84.3% recovery in crack width and 27.8% recovery in fexural strength after ageing.
