A grain rotation model first described by Jeffery is applied to quantitatively predict texture development and texture heterogeneity in hot‐worked β‐Si 3 . Comparison of model predictions and experimental results indicates that such models can successfully priedict the texture developed in β‐Si 3 N 4 with significant differences observed at height reductions greater than 60% (true strain ∼−0.9). Applications include a description of textures in hot forging, plane strain compression, and various green body forming techniques including tape casting and extrusion.
