Beschreibung
Zusammenfassung:	A nondestructive evaluation method for detecting cracking (5) in a metal tube body (1) by specified inspection devices (6) and (7), wherein a cooling treatment, a heating treatment, or a cooling and heating treatment is applied to the specified position of the tube body (1) to cause deformation so as to open the cracking (5) present in the tube body (1) for elicitation. Then the tube body (1) is inspected by using the inspection devices (6) and (7).
