bending impact and fatigue strength. We found that the developed steel that was carbonitrided with a content of about 0.9 mass%, and then shot peened hard, has a pitting life of roughly 4.5 times...Development of High Strength Steel Designed for Carbonitriding with High Nitrogen Content to Be Used for Automatic Transmission Gears Youichi Watanabe1 (1.Nissan Motor Co., Ltd., 6-1, Daikoku-cho......
. Moreover, the results of the mechanical tests show that the process significantly increases the yield and ultimate tensile strengths, bending strength, hardness and fracture toughness of the commercially pure titanium so that it can be used as a replacement for metallic alloys used as biomaterials. Key words: commercially pure titanium; equal channel angular pressing; tensile strength; bending strength......
A and type B systems. Slope stability analyses were carried out to study the relationships between soil and nail reinforcement and bending stiffness as well as combined axial tension and shear forces. Factors of safety were calculated in relation to the number of nails and their outside diameters. Both soil and rock slopes were included in this evaluation. Key words: soil nailing; bending......
