STRENGTHENING MECHANISMS IN DISPERSION HARDENED NICHROME,
Abstract
The strengthening mechanisms in TD Nichrome was examined at temperatures between 70F and 2000F. A contribution to strength at all temperatures comes from solid solution hardening, dispersion hardening and dislocation substructure hardening. Grain size hardening is operative only below 800F; at higher temperatures a fine grain size results in a loss of strength. The contribution of dispersion hardening is almost constant up to 1000F and then drops sharply. Dislocation substructure strengthening becomes increasingly important as the testing temperature is increased and is the major strengthening factor at 2000F. (Author)
