It . 1.1 This test method covers the determination of comparative hardness values by applying the Ultrasonic Contact Impedance Method (UCI Method). 1.2 The values stated in SI units are to be regarded as standard.
2 UCI hardness test method 2.1 The UCI measuring principle As the name ‘ultrasonic contact impedance’ suggests, the principle is based on the use of ultrasound excitation to determine the hardness of the test piece. A resonating rod is set into a longitudinal oscillation by multiple piezo elements, mounted to the upper end of the rod.The UCI Hardness Tester TCM-U2 operates according to the Ultrasonic Contact Impedance (UCI) method of hardness testing, and is standardized according to ASTM A1038 . The basic operating principle is that hardness is measured by detecting the frequency shift of a longitudinal oscillating rod fused to a Vickers diamond indenter.Hardness testing within the realm of materials testing. Today, hardness testing is one of the most widely used methods in mechanical materials testing, especially for metals. On the one hand, this test method can be used to find qualitative relations to other material properties (e.g., strength, stiffness, density) or to the material behavior under certain stresses (e.g., abrasion .
During the decades, various destructive and non-destructive hardness test methods have been developed. The non-destructive methods are portable and can be used on materials at the service, but a widely accepted non-destructive hardness test method, the ultrasonic contact impedance technique, is limited to measure the surface hardness. Each hardness testing method has a range of loads that are applicable to the use of the test. Some tests, like the Vickers hardness test, can be used on a macro scale as well as a micro scale. The loads required are listed in Table 1 below: Table 1: Different Hardness Test Methods and Their Corresponding Loads. Method Load Range 1.1 This test method covers the determination of comparative hardness values by applying the Ultrasonic Contact Impedance Method (UCI Method). 1.2 The values stated in SI units are to be regarded as standard.The Ultrasonic Hardness Tester is a non-destructive ultrasonic testing method used to measure materials’ hardness. The principle of this instrument requires a tool (gauge). The tool will be applied to the sample on which a probe will be fixed and then this probe will send out ultrasounds which will determine the hardness of the sample.

Features: State of the art, digital ultrasonic portable hardness tester is designed to test the hardness of metal parts. Loaded with useful functions only found on high priced models the PHT-6000 series portable hardness testers are clearly setting a new industry standard by being the most accurate, comprehensive and versatile portable hardness testers on the market today. Contact and Immersion Testing. Ultrasonic testing can also be split into two main types: contact or immersion testing. Contact ultrasonic testing is typically used for on-site inspections accessibility or portability. Contact ultrasonic inspection can be performed where only one side of a test specimen as reachable, or where the parts to be .The UCI Hardness Tester TCM-U3 operates according to the Ultrasonic Contact Impedance (UCI) method of hardness testing, and is standardized according to ASTM A 1038. The basic operating principle is that hardness is measured by detecting the frequency shift of a longitudinal oscillating rod fused to a Vickers diamond indenter. Overview of Non-Destructive Hardness Testing Methods. Since hardness testing has multiple applications, the techniques vary a lot, too. The optimal test method depends on the tested item’s size, shape, texture, and .
ASTM A1038 Full Name. ASTM A1038 – Standard Test Method for Portable Hardness Testing by the Ultrasonic Contact Impedance Method. Scope. This test method covers the determination of comparative hardness values by applying the Ultrasonic Contact Impedance Method (UCI Method).. Keywords
In the past few decades research work and development of testing procedures and equipment have been carried out to characterize microstructural and mechanical properties of materials by ultrasonic testing methods. Ultrasonic testing parameters are significantly influenced by variations in microstructural or mechanical properties of materials.
