| Abstract(J) | 本研究では，報告事例の少ないダイカスト材ADC12-Fを用いて摩擦攪拌接合を行い，その接合強度と破壊形態を展伸材と比較しつつ定性的に評価した．また，ADC12-F同種接合だけでなく，A5052-H34とA6061-T4の2種類の展伸材との異種材料同士の接合を行い，詳細な破壊解析に基づいた接合強度の評価を行った． Translation |
| Abstract(E) | In this study, friction stir welding of similar and dissimilar materials was carried out using die casting aluminum alloy ADC12 and wrought aluminum alloy 5052 and 6061 to evaluate the tensile strength and to analyze the fracture of jointed materials. In ADC12 similar joint, the tensile strength was lower than that of base material. Joining efficiency was 86% and adequate tensile strength was obtained. Softening due to heat generated during friction stirring was not observed. The fracture location was the Stir Zone. The tensile strength of similar joint is lower than that of the base material due to the different shape and distribution of the Si phase in the Stir Zone. In dissimilar joints of ADC12with 5052 and 6061, joining efficiency was more than 80%. Placing a material with lower tensile strength at the Advanced Side will result in higher tensile strength than placing it in the Retreating Side. The fracture location of dissimilar joints was the softened point of the wrought aluminum alloy (5052, 6061), where the tensile strength of base material is lower than ADC12. |
