At the Kazan National Research Technical University named after A. N. Tupolev (KNITU-KAI), a technology has been developed to improve the properties of metal during melting. This was reported in the press service of the university.
Adding sound waves with a frequency of 40 kHz increases the volume of molten metal by a third and makes its structure more uniform, which is especially important in the production of parts for the aviation industry.
During laser processing (welding or 3D printing), the metal was additionally exposed to ultrasonic waves.
Adding ultrasound helps to better mix the molten metal and distribute heat more evenly. This is especially important in the production of parts for which high quality requirements are imposed.
To study the effect of ultrasound on the metal melting process, scientists have developed a computer model. It takes into account the flow of molten metal and the propagation of sound waves.
Experts continue to work on determining the optimal parameters of ultrasound exposure for various metals. The technology is planned to be used to improve the quality of parts in various industries — automotive, aviation and medical.
Earlier www1.ru reported that a laser for the thermal hardening of metal was created in Saratov.
