TEST BODY MANUFACTURING METHOD AND EVALUATION DEVICE OF TEST BODY MANUFACTURING CONDITION

摘要

PROBLEM TO BE SOLVED: To simply give a deep crack to a test body. SOLUTION: The test body, to which a grain boundary is given, is manufactured by performing a low melting point metal flame spraying process for applying the flame spraying of a low melting point metal of which the melting point is lower than that of the test body 11 to the surface of the test body 11 to form a low melting point metal layer 12 and a heating process for heating the vicinity of the low melting point metal layer 12 so that the temperature of the test body 11 covered with the low melting point metal layer 12 becomes higher than the melting point of the low melting point metal.
