FRACTURE MICROMECHANICS IN HIGH-STRENGTH STEELS AND TITANIUM.
Abstract
To characterize the structural factors that govern the heterogeneous micromechanics of flow and facture in highstrength materials, a variety of high-strength steels and a high-strength titanium alloy were investigated in detail. Among the alloys studied were AISI 4340, a low-alloy highstrength steel; Type H-11, a secondary-hardening hot-work steel; Types 410 and 422, martensitic stainless steels; Type 301, a deformation-strengthened steel; Type PH15-7Mo, a precipitation hardened semiaustenitic steel; 300 grade 18 Ni marage steel; Cr-Co stainless marage AFC-77; and B-120VCA, an age-hardened beta titanium alloy. In these materials, the detailed fine structures are characterized and related to strength and fracture properties. Thus, a better understanding of the interrlation between strength and structural factors was achieved. (Author)
