Abstract

PURPOSE:To enbale a material property to be decided in a rapid and non-destructive manner by means of an on-line system, by a method wherein an incident angle of a corrugated wave elastic wave toward the inside of a steel plate from a panel wave elastic wave oscillator is changed to find a propagating speed in the steel. CONSTITUTION:A panel wave elastic wave, oscillated from an oscillator 1, is propagated into an object 3 to be tested through an acoustic coupling medium in a coupler 2, and a back echo from the object 3 to be tested reaches the oscillator 1 again through the accoustic coupling medium. Then, a frequency is kept constant and an incident angle theta of a panel wave is changed, and this finds a maximum value of a reflection echo height and a current incident angle. A phase speed corresponding to the incident angle is then computed, and the propagating speed of the panel wave is found from the speed V to decide a material property depending upon the aggregation organization of the object to be tested. This permits finding of the material property of the steel plate including a surface internal anisotropy thereof by means of an on-line system.
