概要: 金沢大学理工研究域機械工学系<br />Bi-doped Cu bicrystals with various[001]and[011]twist boundaries have been tensile tested at r oom temperature and 543K. The fracture stress and fracture strain depend strongly on the misorientation angle and tensile temperature. The difference in the degree of embrittlement among different grain boundaries is more significant at 543K. The fracture stress and fracture strain at 543K against misorientation curves display some clear peaks ; θ=23°(Σ13A), 28°(Σ17A), 37°(Σ5)and 44°(Σ29A)for[001]boundaries and θ=50°(Σ11), 59°(Σ33C), 71°(Σ3)and 83°(Σ57B)for[011]boundaries. For the two types of grain boundary, a good correlation is found between the degree of embrittlement and grain-boundary energy. A higher-energy boundary is more brittle and fractures more easily with a lower tensile stress. The fracture stresses of[001]boundaries are greater than those of[011]boundaries. 続きを見る
