Using the X-ray pole figure method, hardness test and optical metallography, rolling and recrystallization textures were investigated. After 98% cold reduction, copper type rolling texture developed at the rolling surface. Sharp cube texture with orientational spread around rolling direction was observed after annealing. To intensify the cube texture, the process of partial annealing and light rolling before final annealing is effective in the platinum-rhodium alloy as in the case of aluminum. Orientational spread around the rolling direction was attributed to lattice rotation during rolling in the cube band near to the specimen edge.
