Abstract
The kinetics of (110)[001] secondary grain growth, the temperature dependence of selectivity to a (110)[001] texture, and the kinetics of desulfurization in cold rolled-decarburized, thin sheet (semiprocessed 3 pct Si−Fe) were measured as were the parameters requited to produce (110)[001] grain-oriented sheet by high temperature strip annealing. Kinetic studies revealed that (110)[001] grain growth in several semiprocessed sheets exhibited the following characteristics: 1) sigmoidal growth kinetics; 2) an activation energy of ∼64 Kcal; and 3) essentially complete (110)[001] secondary grain growth within 8 min at temperatures of 1000°C and higher. Measurements of magnetic torque properties and pole figures of isothermally annealed semiprocessed sheet showed a degradation in selectivity to a (110)[001] texture above 1050°C. Desulfurization kinetics were in good agreement with a theoretical diffusion model which takes into account sulfur removal in the presence of a dispersed second phase of MnS particles. A two-stage high temperature strip annealing cycle in dry hydrogen produced (110)[001] grain-oriented sheet having magnetic properties comparable to those obtained by conventional box annealing.
