Description

Technical Field
The invention relates to the field of nondestructive testing, in particular to a holographic testing device for mechanical properties, elastic modulus and damage of a high-temperature material.
Background
As the application field of the material is expanded, the defect damage problem is highlighted. It is known that various defects are generated inside a material component due to the production process, material characteristics, severe service conditions and the like of materials, and the defects are generally distributed unevenly and randomly inside a material structure, so that many important structural components fail and even break due to internal damage defects in the actual service condition. The material defects can seriously affect the strength and the service performance of the member, the elastic modulus is one of the important core mechanical properties of the material, the deformation resistance of the member is reflected, and the elastic modulus and the material damage defects are important parameters for guaranteeing the rigidity of the structural member, so that the detection and evaluation of the elastic modulus and the material damage defects of the material under the actual service condition are important links for guaranteeing the safe service of the material. In reality, most of structural members are actually used in a high-temperature environment and bear a large load, so that the development of a high-temperature material mechanical property elastic modulus and damage holographic testing device is necessary.
The conventional nondestructive testing device can only carry out related detection on one of material performance parameters aiming at a structural part, cannot carry out multiple real-time detection under the condition of simulating actual service, and is difficult to carry out holographic imaging aiming at internal damage defects of a test piece in the loading process. The ultrasonic nondestructive testing method has the advantages of high resolution, good accuracy, low cost, convenience in operation and the like, can realize qualitative and quantitative characterization and evaluation of internal defects and damages of materials based on the mathematical expression relation between ultrasonic echo signals and the internal defects of the test piece, is conveniently applied to visual and automatic nondestructive testing of various actual material structural parts, and is an important testing method for realizing intelligent testing of composite materials most probably. However, most of conventional ultrasonic testing can only perform single mechanical property parameter detection in high temperature environment, and meanwhile, a plurality of sets of transmitting and receiving ultrasonic transducers are required, which greatly increases the structural complexity, for example, chinese patent (CN108120768A), a method and an apparatus for ultrasonic testing of high temperature elastic modulus, a sound wave transmitting and receiving transducer arranged in a heating furnace performs high temperature elastic modulus measurement, and only can perform single mechanical property parameter detection. As shown in chinese patent (CN103961142A), ultrasonic holographic imaging system and method, a plurality of transceiver elements transmit and absorb ultrasonic waves, so as to perform holographic imaging on a test piece, but only a single holographic imaging is performed and a plurality of sets of transceiver elements are used, which increases the structural complexity and is not suitable for high temperature and elastic modulus measurement.
Compared with the conventional ultrasonic nondestructive detection technology, the ultrasonic phased array technology has the advantages of flexible and controllable sound beam, high detection precision and sensitivity, high detection efficiency and the like, and meanwhile, the ultrasonic phased array probe has a large number of ultrasonic wafers, is small in size, can realize multichannel parallel detection, realizes the spontaneous and self-receiving of ultrasonic waves, and greatly improves the detection precision.
In general, based on the difficulty that the internal damage defect of the material and the real-time detection of the elastic modulus of the material are difficult to detect under the high-temperature service condition at present, an ultrasonic phased array technology is designed, so that the elastic modulus can be accurately measured under the high-temperature environment, and the 3D holographic imaging equipment for the internal damage defect of the material in the loading process is very important.
