Physical Characterization of Electronic Materials,

Abstract

Compressive deformation techniques were studied for the fabrication of fine grained polycrystalline KCl from high purity single crystal starting material. The processing parameters included temperature, total strain, strain rate, heating and cooling rates and stress. The experimental conditions were optimized to produce crack-free fine grained KCl windows of six inch diameter and above. Grain size and crystallographic texture were measured in as-fabricated windows. Proportional limit, modulus of rupture, and impact strength values were also obtained on the polycrystalline material. No detectable differencies were obtained in optical absorption at 10.6 micrometers on the polycrystalline windows as compared with the unprocessed KCl single crystal material. (Author)
