Abstract

PURPOSE: To make accurately a metal thermal fatigue test, etc., by flattening the shape of the solid-liquid phase interface of a sample, by employing both resistance heating and high-frequency inductive heating for the metal sample.
CONSTITUTION: Sample 2 is inserted into quartz tube 1. On both the sides of this sample 2, direct feed heating electrodes 3a and 3b are mounted and a high-frequency inductive heating work coil is provided nearly in the middle between quartz tube 1 and sample 2 covering them. Now, only direct feed heating generates axial temperature distribution P with its uniform heat band less than W, forming solid-liquid phase interface S1 in a concave shape. Then, combining direct feed heating and high-frequency inductive heating provides axial temperature distribution (q) with axial uniform band length W and improves the temperature distribution in the axis core direction, so that flatness ΔW of solid-liquid phase interface S3 will remarkably improve. Therefore, tests such as a metal fatigue test can accurately be carried out.
