Description
на частоте 2 МГц следующих материалов:at a frequency of 2 MHz the following materials:
1.Капролон Б1. Caprolon B
2.Оргстекло2. Plexiglass
3.Титановый сплав ВТ 3-1 4. Алюминиевый сплав Д1бТ Способ оценки реальной чувствительности ультразвукового контрол изотропных материалов заключаетс в следующем. Измер ют по известной методике коэффициент затухани ультразвука в исследуемом материале. С помощью тонкой пластины из исследуемого материала определ ют величину ослаблени аттенюатора при уменьшении амплитуды донного эхо-сигнала и пластины на 2/5, наблюдаемого на экране электроннолучевой трубки. По положению шкалы аттенюатора определ ют величину AJ - запас усилени эхо-дефекгоскопа. От линии ординат нормированной АРД-диаГраммы из точки А,- провод т линию минимально регистрируемого эхо-сигнала А A,-2 и по точкам пересечени этой линии3. Titanium alloy BT 3-1 4. Aluminum alloy D1bT A method for evaluating the real sensitivity of ultrasonic testing of isotropic materials is as follows. Measured by the known method, the attenuation coefficient of ultrasound in the test material. Using a thin plate of the material under study, the attenuation value of the attenuator is determined with a decrease in the amplitude of the bottom echo signal and the plate by 2/5 observed on the screen of the electron-beam tube. The position of the attenuator scale is used to determine the value of AJ, the margin of amplification of the echo deflectoscope. From the ordinate line of the normalized auto irde diagram from point A, draw a line of the minimum recorded echo signal A A, -2 and along the points of intersection of this line
с семейством кривых АРД-диаграммы стро т кривую реальной чувствительности контрол материала.with a family of curves, the DGS-diagrams construct a curve of the real sensitivity of the material control.
Предлагаемый способ исключает не .обходимость разрушени деталей из исследуемого материала и значитель но ускор ет процесс измерени реальной чувствительности ультразвукового контрол изотропных материалов.The proposed method eliminates the need for the destruction of parts from the material under study and significantly accelerates the process of measuring the real sensitivity of ultrasonic testing of isotropic materials.
