Abstract
Cylindrical samples of polycrystalline semiconductor-grade silicon have been compressed 30 pct at 1380°C at a rate of 0.08 s-1. The starting material had a strong «110» fiber texture, resulting from its growth by chemical vapor deposition; the fiber axis was perpendicular to the compression axis. The compression texture is very clearly defined after only 30 pct deformation, and has a «110» axis parallel to the compression axis and a «111» axis parallel to the original «110» fiber axis (perpendicular to the compression axis). Annealing for 10 min at 1380°C causes recrystallization. The recrystallization texture has a «100» axis parallel to the compression axis, and a «110» axis parallel to the original «110» fiber axis. Compression of a recrystallized sample gives the same deformation texture as does compression of the original material.
