Abstract : This report represents the culmination of a three-year research program on five aspects of strengthening mechanisms in steel: (1) atomic displacements in martensite, (2) ausforming of iron-nickel-carbon martensites, (3) strain tempering of iron-carbon martensites, (4) strain hardening of body-centered cubic versus face-centered cubic metals at very high strains, and (5) modes of fracture in martensite. The underlying reason for these five investigations was to provide further basic understanding of the strengthening processes at play in virgin and tempered martensites, with and without thermomechanical treatments.
