“…May and Kronberg 2 examined loss of strength in MgO single crystals using three point bending tests up to 1000 • C. Later, various studies focused on the effect of temperature on strength of ceramic crystals, metallic single crystals, metallic alloys, and ceramic composites. [3][4][5][6][7][8][9] Fundamentally, lattice expansion associated with increase in temperature has been attributed to loss of strength as a function of temperature. Such reasoning fundamentally reflects change in static properties of lattice (elastic constant, cohesive energy, etc.)…”

“…This comparison seems to be reasonable, since the tensile stressstrain curves of boron-doped Ni3(Al, Ti) single crystals (35) are entirely shifted upwards as compared with those of no boron-doping ones for all tensile axes (36). As a result, the values of the work-hardening rates are almost the same for both alloys.…”

Tensiletests at room temperature were performed on recrystallized Ni3Al doped with boron having Both yield and flow stresses depend on grain size in agreement with a Hall-Petch relation when the specimen size effect is taken into account. The increase in Hall-Petch slope with strain is explained in terms of the difference in work-hardening rate for different grain sizes. The increase of lattice friction stress with strain is found to be analogous to the single crystal properties. While the {111} cracking is predominant without necking for coarse-grained specimens, the slant-type fracture and cup-cone fracture preceded by a necking is mainly observed for intermediate and finegrained specimens, respectively. Large elongation is developed when the intersection of slip bands becomes insufficient to produce the {111} cracking, and the void formation which results in the cup-cone fracture is retarded.
