Effect of Annealing on the Properties of TZM Molybdenum Alloy Foil
TZM molybdenum alloy shows superior mechanical properties and higher recrystallization temperature than pure molybdenum,making it suitable for a wider range of application scenarios.TZM foil can replace pure molybdenum foil in electronic and other fields.The microstructure and mechanical properties of TZM foil after different annealing temperatures and high-temperature short-term annealing heat treatment was studied in this paper.It is found that annealing at 900℃ can achieve stress relief and maximum elongation of the foil;High temperature short-term annealing enhances the tensile strength of the material,and after two times high-temperature short-term annealing,the foil exhibits maximum strength and higher elongation;The cupping test similar to mechanical properties,annealing at 900℃ resulted in a maximum cupping value of 3 mm for the material.After two times high-temperature short-term annealing,the cupping value increased by 23％.
