| RESEARCH INTO PROPERTIES OF NICKEL-BASED SUPERALLOYS FOR GLASSWORKS |
Abstract
The První brněnská strojírna Velká Bíteš Company has developed a process of precise casting suitable for parts to be used in glass industry. The parts were made of nickel-based superalloys designated 141, 141H, 141I, 145 and 2.4879. The mechanical properties and structural stability of the alloys were determined within the temperature range of < 20; 1100>°C.
The research aimed to study the issues of structure-related processes occurring at high temperatures, and to reveal the relation between structure and mechanical properties in the superalloys being newly introduced. The project tried primarily to generate data on the impact of chemical composition, i.e. data useful when selecting the alloy best suited to a given purpose, and to gather sufficient body of information on the alloys' structural stability, their major mechanical properties and the property degradation through long-term heat exposure. In this way the study attempted to develop a reliable database for designing the castings and introducing them into the engineering practice.
