ALLOYS WITH MODIFIED CHARACTERISTICS ZLITINE Z MODIFICIRANIMI LASTNOSTMI

摘要

Industry has a permanent need for new materials to improve the performance of constructions. However, the development of new materials is a complicated and costly process, and in many cases the existing materials with modified characteristics are used. By the use of certain technological processes of producing liquid metals, deformation processes, thermal and surface treatments, the mechanical and exploitation characteristics of existing materials can be improved. In this paper is an overview of several research activities at the Institute in Zenica with the goal to improve the characteristics of some materials in use in the air and car industries. With semi-industrial facilities and in laboratories of the institute some researches where conducted on stainless steels and maraging steels as well as on superalloys based on nickel and iron.
