Abstract

In K-Al-Si doped heavily-drawn tungsten wires the boundaries revealed by transmission electron micrographs are mostly high-angle grain boundaries both in the as-received and in the partially annealed state. An important part of the stored energy and the excess electric resistivity is due to the grain boundaries. During coarsening of the fiber structure the number of the 120 degree grain edges increases extensively. The bodily motion of the fine inclusions dragged by the grain boundaries seems to play an important role in the coalescence of the inclusions. Refs.
