Abstract:
Stress-aging is a new treatment for alloys that results in improved strength properties with little, or no, loss in ductility. Specific treatments result in a maximum proportional limit or elastic capacity, b maximum 0.1 offset yield strength or c best generally high properties. The proportional limit may be increased by 65,000 psi above the initial tensile strength, the 0.1 offset yield strength may be increased by 30,000 psi, with elongation ranging from 8 to 14, while reduction of area remains essentially constant 50-54. Stress-aging raises 4330 steel into the lower range of ultra-high-strength steels. Author
