摘要： 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.

摘要： PURPOSE:To evaluate average aggregation texture and average crystal grain size quickly and nondestructively by an on-line system, by transmitting a pulse shaped elastic wave in the direction of a plate thickness from the surface and receiving a back echo reflected from the bottom. CONSTITUTION:A transmitting end 1 and a receiving end 2 are incorporated into a unitary body, and water is supplied into a junction between said body and a steel plate 3 as an acoustic medium from a water nozzle 4. By using such a transmitter T and a receiver R, the pulse shaped elastic wave is transmitted in the direction of the thickness of the steel plate 3 from the transmitting end 1. The back echo from the bottom surface is received by the receiving end 2. The transmission speed and the elastic constant in the steel plate are measured from the transmission time. From these data, the average aggregation organization and the material characteristics based on said aggregation organization in the direction of the plate thickness is measured. Then the energy of the received elastic wave is measured. From the ratio between said value and the energy of the transmitted elastic wave, the average crystal grain size in the direction of the plate thickness of the object to be measured is obtained.

摘要： PURPOSE:To measure the surface and internal characteristic of a running plate material simultaneously, by inputting continuous X rays to the surface of the running plate material, and detecting and analyzing the transmitted X rays, which are emitted in a straight line, and the transmitted and diffracted X rays, which are emitted at the same angle as the incident angle to the side of the surface normal. CONSTITUTION:X rays 22A are continuously inputted to the surface of a running plate material 10 at a specified incident angle theta with respect to the surface normal B. The X rays 24A, which are transmitted straight through the running plate material 10, are detected by a transmitted X-ray detector 24. The difference between the amount of the transmitted X rays and the amount of the incident X rays 22A is corrected. Thus the thickness of the running plate material 10 is measured. Transmitted and diffracted X rays 26A are emitted at the same angle theta as the incident angle theta on the same side of the incident X rays 22A with respect to the surface normal B of the running plate material 10. The X rays 26A are detected by a transmitted- and diffracted-X-ray detector 26. The intensity of energy is analyzed and the result is corrected by the attenuation amount of the transmitted X rays 24A when the plate thickness is measured. In this way, the surface and the internal characteristics of the running plate material are measured. Thus on-line measurement can be performed.

摘要： PURPOSE:To reduce measuring errors caused by changes in the sensitivity of elements due to variations in the quantity of light and the ambient temperature, by correcting the measured value according to variation in the intensity of light of a light source at a specified wavelength detected with a light detecting element through an optical fiber and a wavelength separation element. CONSTITUTION:An object 12 to be measured is irradiated with a light source 10, the reflected light is spectrally analyzed with a reflection type diffraction grating 36 through a focusing lens 30, a slit 32 and a collimator lens 34 and then, intensities of reflected lights with various wavelengths are received simultaneously with an array type light detecting element 40 via a concave mirror 38. The signals detected by the element 4 are colorimetrically computed with a digital processor 46 via an amplifier 42 and an A/D converter 44 and a colorimetric value is outputted with an output unit 48. Moreover, a part of light from the light source 10 is introduced to an array type light detecting element train 40, for example, with three optical fibers 50, which are each combined with a wavelength separation element 52 with the determined transmission wavelength. Thus, the calibrating work with a standard white plate can be eliminated by monitoring the intensity of the light source at the specified wavelength.
