Abstract
A refractory metal plate is provided. The plate has a center, a thickness, an edge, a top surface and a bottom surface, and has a crystallographic texture (as characterized by through thickness gradient, banding severity; and variation across the plate, for each of the texture components 100//ND and 111//ND, which is substantially uniform throughout the plate.

-38. (canceled)
A method of forming a refractory metal plate, the method comprising:
- (A) providing a workpiece having a size suitable for a target plate, the workpiece comprising a refractory metal;
- (B) asymmetrically rolling the workpiece one or more times at an angle of incline between 2° and 20° relative to horizontal, thereby forming a rolled plate;
- and
- (C) annealing the rolled plate to achieve substantially full recrystallization.
