The plastic flow process around a spherical dilatated inclusion has been previously sketched as a “dislocation shell” emission idealizing patterns of collectively moving prismatic circular loops. This elastic description of relaxation is here rei

The mode of damage in tension of a new Al-Si-Fe alloy made by spray deposition was studied. This alloy has a composite type structure composed of silicon and intermetallic particles in an aluminium matrix. In situ tensile tests in the SEM, with gold

A method of calculating fatigue life of bearing steels, which accounts for the material fatigue process in relation with its microstructure, is required for optimizing these materials. Such a new approach is presented for bearing steels submitted to
