| Research Abstract |
In order to realize the high quality of casting amorphous alloys with small amount of cast defects, we tried to control the feeding rate of suction casting and the shape of hearth of tilt casting. As a result, we achieved a high quality cast amorphous alloy with good visual by neck eye to compared with the conventional processed cast amorphous alloy. Based on these results, commercialization of productions has been tried by some companies, and we are making the application about the know-how contract and patent submissions. We construct whole process of fabrication of cast amorphous alloys, and the reproducibility was remarkably improved about the deviation of density and modulus to be within 1% (about 5% in conventional process).
