NACA Technical Notes

Note presenting some of the factors believed to affect the strength and ductile-to-brittle transition temperature of bainitic steels, including mean ferrite path and degree of internal strain. Strength was measured by diamond pyramid hardness and transition temperature was obtained from a tensile impact test on small notched specimens. Results regarding strength and hardness of bainites, ductility (transition temperature) of bainite
