Correlation between Defect Structure and the Strength Properties of Silicon for Various Means of Plastic Deformation

Abstract

The effect of combined deformation on changes in the plastic and strength characteristics of silicon is investigated. A notable increase in plasticity upon combined deformation compared to traditional hot deformation is revealed. It is shown that the microhardness of silicon is reduced as plastic deformation increases. The mobility of dislocations has an appreciable effect on the strength characteristics of silicon single crystals. Surface microstructures of the deformed samples are studied. A possible explanation for the observed effects is given.
