Outline of Final Research Achievements

We performed precise measurements of many number of high temperature liquid alloys using a electromagnetic levitation technique under static magnetic fields.We obtained the density of liquid Fe-B with whole concentration range for the first time. The main purpose of the research works is to make a model of presumption of liquid alloy’s density with concentration change. We could not complete to make the model, but we obtained the relationship between molar volume and short-range order of liquid structure by polyhedral analysis of high-energy x-ray diffraction data. The relationship will develop the way of making a model of presumption of liquid alloy’s density in future.
