| dc.description.abstract | This paper investigates the effect of strain rate on the properties of Alloy 617 under low-cycle fatigue (LCF) at room temperature (RT). The LCF life properties and damage mechanism are studied for this alloy over a range of strain rates (5E-4 ~ 1E-2 s-1) under a fully-reversed controlled total strain range of 1.2%. It is found that the LCF life of Alloy 617 is strongly influenced by time-dependent mechanisms, in terms of slow strain rate testing (SSRT). The relationship between total strain, plastic strain, and time to failure with strain rates is established and expressed by means of a power law function to describe fatigue life. Metallographic examination is carried out on the fractured specimens with the help of an electron microscope, and fractography is discussed to distinguish the effect of SSRT on the physical damage characteristics under LCF loading | en |
| dc.description.abstract | Článek analyzuje vliv rychlosti deformace na únavové vlastnosti slitiny Alloy 617 při nízkocyklové únavě za pokojové teploty. Byl studován mechanismus poškození a životnost slitiny při různých rychlostech deformace (5E-4 ~ 1E-2 s-1). Výsledky ukazují, že LCF životnost Alloy 617 je silně ovlivněna procesy závislými na čase, zejména v případě testů SSRT. Fraktografická analýza byla provedena pomocí elektronového mikroskopu, aby se identifikoval vliv pomalé rychlosti deformace na poškození materiálu | cz |
