Sinter-forging temperature and also dwell time at that temperature should also influence the hyper elasticity of this
composite. For this reason, another sinter-forging process was programmed following this process.
Again, mapping elementary analyses is very indicative analyse for a care reflection on the composite structure in order to
evaluate the distribution of the reinforcement particles as very fine particles in the matrix and homogeneity of the composite
structure as presented in the Fig. 5.4.
