Abstract

Systematic investigations on the microstructural evolution of a bimodal eutectic (Ti70.5 Fe29.5)91 Sn9 ultrafine composite containing Ti3 Sn dendrites upon compression reveal that local deformation of the dendrites dominates the early stage of deformation with a plastic strain of εp =5.8%. After further deformation (εp =10.2%), a wavy propagation of shear bands indicative of dissipation of the shear stress is caused by a rotation of the coarse eutectic structure along the interfaces of the bimodal eutectic structure.
