| Outline of Final Research Achievements |
In this research, the new hybrid continuity casting technology for developing a high quality (high intensity and Takanobu nature) light metal casting was proposed. In this work, high velocity revolution casting, the continuity casting method with an ultrasonic wave, and various addition elements were added in conventional cast aluminum alloy.
From the above casting technologies, the quality cast aluminum alloys are creatable with high strength and high ductility, in which high lattice strain, solid solution and high precipitation strength occurs. Nano powders were also valuable technique to make high mechanical properties. We have developed new cast aluminum alloys with additional elements, which has received the “2016 Second Best Paper Award” from Journal of Mechanical Science and Technology. The paper was selected for the award based on the expectation that the research result will contribute to future development of mechanical engineering.
