Abstract

The growth of advanced technologies involves the development of materials that can withstand extreme environmental conditions, particularly elevated temperatures. This paper presents an in-depth examination of the mechanical properties of materials designed specifically for use in high-temperature environments, such as however confined to aviation, nuclear-powered reactors, and electrical power systems. Relevant significance is associated with assessing the mechanical robustness, resilience to deformation under constant stress, and ability to cope with high temperatures over a longer time for these materials. This study explores recent developments in materials science, focusing on the products made in alloys, ceramics, and composite materials such as nickel-based superalloys, silicon carbide (SiC), and composite based on zirconium diboride (ZrB2). A significant focus is placed on innovative testing methods, including high-temperature tensile tests, thermal shock resistance assessment, and fatigue testing, as these play a critical role in evaluating the performance of substances under challenging conditions. Further, this study explores the consequences of these findings on the choice of materials and the design process in engineering applications. Titanium superalloy operates effectively at lower temperatures, whereas Nickel-based 70% of the initial strength when heated to a higher temperature of 1100°C superalloy behaves superior under more extreme conditions.
