THE BRITTLE-TO-DUCTILE TRANSITION IN SILICON

Abstract:

In order to study the brittle-to-ductile transition of a strong solid, silicon was chosen as a model material. Single crystals of silicon with semielliptical surface cracks parallel to the (111) cleavage plane, introduced by indentation, were deformed by four-point bending. The brittle-to-ductile transition is very sharp; brittle failure occurs by cleavage below a critical temperature Tc; in the transition region failure also occurs by cleavage, but at a stress intensity considerably greater ...
