THE METHOD OF MICRO-UPSETTING IN UNEVEN TEMPERATURE DISTRIBUTION
Abstract
A method of determining the plastic properties of the material under the conditions of microforming at elevated temperatures was presented. This involves performing the process of upsetting a cylindrical micro sample between flat tools of different temperatures. As a result of the heat flow in the volume of the sample the nonuniform temperature distribution is observed. It causes uneven distribution of deformations and a shape similar to the truncated cone is obtained. Based on the measurement of the sample side contour, FEM simulation of the process and the known temperature at several points of tooling it is possible to determine the dependence of the plastic resistance on the temperature within the given range. Dependence is derived from one experiment. This method is recommended for studies where the number of samples for analysis is limited. The method allows to quickly determine the temperature characteristics of a material. A sample analysis of selected bulk metallic glass was presented.
