Abstract:

Methods for fast determination of the kinematic viscosity of high-temperature metallic melts are considered. The experiments may be standardized, simplified, and shortened, by using the parameters of two points on the oscillatory damping trajectory that differ by a factor e and also by means of bipolar synchronized torsion of a melt-filled crucible suspended on an elastic fiber. By measuring the parameters of metallic liquids, materials may be analyzed, and recommendations may be made for the production of alloys with specified characteristics. The feasibility of fast measurements with accuracy acceptable for most cases is analyzed. The potential for reducing the length of experiments, standardizing experiments, and reducing the subjective influence of the researcher is considered. Bidirectional torsion reduces the time for a single measurement cycle by a factor of 1.5 and reduces the total torsional time by a factor of 4. The accuracy of the proposed approach is acceptable. © 2015, Allerton Press, Inc.
