his investigation has used flexural test to explore the effect of thermal treatments
i.e. high temperature and cryogenic environments on the mechanical property of Al2O3
|copper matrix micro- and nano-composites in ex-situ and in-situ
These treatments lead to accumulation of non-uniform residual stresses
decreasing the threshold value of crack nucleation and propagation along the particle/matrix
interface region. The amelioration and declination in mechanical properties as a consequence
of thermal conditioning have been discussed in the light of fractography.
