Design of tungsten alloy bar test block for ultrasonic testing
Tungsten alloy not only has high density (17~19 g/cm), but also has a series of excellent properties such as high strength, high hardness, good ductility, good machining performance, small thermal expansion coefficient and good corrosion resistance, etc., which has been widely used in the field of cutting-edge science and technology, military and civil industry.
With the development of modern armor technology, high density tungsten alloy has no toxicity and no radioactive contamination compared with depleted uranium materials
It has become the main armor-piercing material used in the equipment of all countries in the world. With the improvement of military requirements on the comprehensive performance of armor-piercing projectile, the research on the materials used in armor-piercing projectile is becoming more and more in-depth. Most of the focus is on the research of material preparation technology to improve the penetration performance of armor-piercing projectile, while the quality control of components in the processing process is rarely mentioned. However, the existence of defects will reduce the serviceability of the specimen, so ultrasonic detection technology is mostly used for the quality detection of tungsten alloy. The results show that because most tungsten alloy parts are sintered by isostatic pressure and high temperature, the internal defects are complicated and varied. Therefore, in order to realize the reliable detection of specimen quality, in addition to the selection of a reasonable ultrasonic detection method, the design and selection of ultrasonic detection pairs are also very critical, which directly affects the effectiveness of ultrasonic detection methods and reliability of detection results. It is necessary to reasonably design according to the quality requirements of test objects and the provisions of detection standards, so as to achieve the predetermined detection capability.
