Holes at the depth of 1 mm or less were detected by the surface acoustic wave measurement, and those at the depth of 2 mm ~ 5 mm were detected by the normal incidence of the longitudinal wave. The fatigue properties of MMC were also examined by the three-point bending fatigue test, and it was found that the fatigue life of MMC was shorter than that of AC4A due to larger amount of castings defects., text, application/pdf}, pages = {38--38}, title = {アルミ基複合材料鋳物のハイブリッド砂型鋳造法の開発}, volume = {3}, year = {2011}, yomi = {カトウ, ヒロシ and マツウラ, マコト} }
