Abstract (en)
[origin: WO9202654A1] A novel process for making zircaloy mill products with improved fabricability and free of large carbide (silicide or phosphide) particles by a high beta phase heat treatment and/or a low beta phase quenching process followed by rapid cooling and/or air annealing after extrusion or primary fabrication. This also provides final product with uniform equiaxed alpha grain structure and improved aqueous steam corrosion resistance.
