Fracture Processes

The results of comprehensive studies of multifactor processes, mechanisms and criteria for fracture at a variation of the crack-like defect state, loading conditions and mechanical properties of structural materials carried out in the 20th - 21st centuries are presented on the basis of monographic publications and articles published in the journal “Zavodskaya Laboratoriya. Diagnostika Materialov.” Crack resistance of materials and structures has become a key problem of the material science, technology, design, manufacture and service of structures. Fracture mechanics including estimation of the stress-strain and limiting states in a cracks tip formed a scientific basis of the crack resistance analysis Stress intensity factors (linear fracture mechanics) and strain intensity factors (nonlinear fracture mechanics) are accepted as the basic criteria of those states. The basic computational relations for construction of the fracture diagrammes which link the cracks growth with conditions of a static, cyclic, long-term, dynamic loading are presented. Parameters of computational relations are put into correspondence with the features of fracture processes on nano-, micro-, meso- and macrolevels. Prospects of the research and guidelines of further studing crack resistance are discussed.

Abstract Tribaloy alloy T-900 is a cobalt-base alloy derived from an alloy family originally developed by DuPont. Excessive amounts of molybdenum and silicon induce the formatin during solidification of a hard and corrosion-resistant intermetallic coumpound, known as Laves phase. This alloy had improved crack resistance and a lower preheat temperature compared with Tribaloy T-800 (Alloy Digest Co-99, September 1996). This datasheet provides information on composition, microstructure, and hardness. It also includes information on corrosion and wear resistance. Filing Code: CO-100.

Abstract STORA ASP 30 is a high hardenability tungsten-molybdenum alloyed high-speed steel with high cobalt content. It is recommended for cutting tools for hard-to-machine material and high cutting speeds. It has excellent wear resistance, toughness, hot hardness and resistance to tempering. The excellent size stability and good grindability of ASP 30 make it very suitable for tools with a complicated shape. This datasheet provides information on composition, physical properties, microstructure, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-338. Producer or source: Stora Kopparberg, Special Steels Division.
