METHOD FOR MANUFACTURING THIN SHEET OF PURE MOLYBDENUM OR MOLYBDENUM ALLOY SUPERIOR IN DEEP DRAWABILITY

摘要

PPROBLEM TO BE SOLVED: To provide a method for manufacturing a thin sheet of pure molybdenum or a molybdenum alloy, which hardly causes a crack even when deep-drawn, is inexpensive, and is easily supplied. PSOLUTION: The method for manufacturing the thin sheet of pure molybdenum or a molybdenum alloy superior in deep drawability comprises the steps of: warm-rolling or cold-rolling a rolling stock of pure molybdenum or the molybdenum alloy in one direction to produce the thin sheet; and subjecting the thin sheet to treatment for relieving internal-stress anisotropy.
