Summary

MEASUREMENTS OF TENSILE PROPERTIES, FRACTURE TOUGHNESS, AND CREEP PROPERTIES OF THE SUPERALLOY MP35N (35% NICKEL, 35% COBALT, 20% CHROMIUM, 10% MOLYBDENUM) AT 77 AND 4 K ARE REPORTED. THE 0.2% YIELD STRENGTH AT 4 K CAN BE INCREASED TO OVER 2 GIGAPASCALS AFTER A SMALL AMOUNT OF PLASTIC DEFORMATION. ALTHOUGH IT IS EXPENSIVE AND SOMEWHAT NOTCH-SENSITIVE, MP35N COULD BE ATTRACTIVE AS A STRUCTURAL MATERIAL WHEN EXTREMELY HIGH STRENGTH AND CORROSION RESISTANCE ARE REQUIRED.
