Anotace
Project titled “Research and development of advanced precision casting technology of strongly thermally affected parts of new turbochargers from nickel based superalloys” is focused on the research, development and subsequent implementation of new progressive technologies of precise casting into serial production of highly complex radial wheels of turbochargers. A Precision Casting Division of PBS Velká Bíteš a.s., which is the entity submitting the Project is focused on the deliveries of castings from nickel-based superalloys. Designers’ requirements of these modern turbochargers lead to the necessity to introduce better quality heat resistant materials. It is therefore necessary to optimize the technological procedure of precise casting so that the best possible mechanic properties of these castings are achieved. An inseparable part of the Project will thus be extensive tests of the mechanic properties focused on creep and fatigue. The obtained findings will allow mastering of the production of new types of highly demanding castings from nickel-based superalloys and subsequently the implementation of the serial production of the newly developed turbochargers.
