Peak TIME5620 Beijing Times ultrasonic hardness, era, Linyi hardness

 More common Brinell, Rockwell, Vickers, Richter and other test methods. Which Brinell, Rockwell test force, indentation large surface damage to be larger specimens were measured using an optical method Vickers, to be very professional and technical personnel to operate, and can not be directly tested for large workpieces, and ultrasound hardness ultrasonic contact impedance method to compare the samples measured with high precision, fast, easy, portable, easy to operate, non-destructive measurement of other advantages. Ultrasonic hardness tester Beijing Times TIME5620 technical parameters hardness standard: Vickers (HV), Rockwell C (HRC), Brinell (HB), etc; probe size: Φ22 × 153mm; ultrasonic hardness and ultrasonic thickness gauge is the same truth. Ultrasonic Thickness Gauge is (this is known in advance by the thickness actually measured in other ways) to determine the speed of sound through a material of known thickness of the sample block, after, as long as the same material, thickness measurement can be directly ; The ultrasonic hardness tester is used to determine the elastic modulus of a material's hardness by a known sample block (this is known in advance hardness measured by the desktop) (but do not need to know the exact number, that, and the measured vary the speed of sound), then, as long as the same kind of material portable ultrasonic hardness tester, hardness can be a direct hit. Ultrasonic hardness tester Beijing Times TIME5620 technical parameters of the test range: HV 50 ~ 1599 hardness, HRC 20.3 ~ 76, HB 76 ~ 618, HRB 41 ~ 100, HRA 61-85.6, Mpa 255 ~ 2180N / mm2 probe Specifications: Φ22 × 153mm; 2000 can store 20 sets of measurement data and calibration data set; no damage to the workpiece surface, good stability, high precision; traditional hardness test equipment, such as Brinell, Rockwell, Vickers hardness tester indenter are specific to a certain static load test material is pressed into the surface of the ultrasonic hardness, indentation, and then its surface mechanical or optical method to directly measure the size of the domestic ultrasonic indentation hardness to be evaluated hardness test material. Characterization indentation hardness value should be loaded when all the deformable material, but since the hardness values ??in the case of unloading of the read, the measured residual indentation only plastic deformation in the elastic recovery is ignored. On the other hand, the hardness values ??are assumed under the indenter indentation is reflected in real geometry determined on the premise, when in fact the residual indentation with the indenter shape is not entirely consistent. The above two factors depends on the measured values ??of the tested materials are the elastic modulus and yield strength. Essence ultrasonic hardness test is performed by the resonant frequency of the incremental indentation indirect valuation measure is in the case of the probe and test material was loaded contacts were, therefore, to avoid the traditional indentation hardness test and indentation elastic recovery the problem of deformation.
