“…Recent studies show that the behavior observed in slow strain rate tests (SSRT) on stainless steel and structural steel is closely in line with the responses under creep conditions (Calmunger et al, 2013;Luo et al, 2013;Luo et al, 2013). Numerous studies have been conducted to modify and improve the relationship to cover materials model through conventional or adapted methods (Ekaputra et al, 2020;Suastika et al, 2019;Chou et al, 2016;Alie, 2016;Chen, Sun, and Chan, 2014;Nakai and Yokoyama, 2012). However, SSRT is found to be promising as a low-cost methodology for the evaluation of materials capability to respond to such environmental interference.…”

Alloy 617 is identified as a potential material for defense applications, particularly in military air platforms. Therefore, this study aims to examine the impact of strain rate on Alloy 617 properties during low-cycle fatigue (LCF) at room temperature (RT). LCF life properties and damage mechanism of alloy 617 are examined across a strain rate range of (5x10 -4 ~ 10 -2 s -1 ) in a fullyreversed controlled total strain range of 1.2%. Slow strain rate test (SSRT) is found to be a costeffective method for assessing the material capability to respond to environmental interference. This study shows that LCF life of Alloy 617 is strongly influenced by the time-dependent mechanism, in terms of SSRT. The relationship between total strain, plastic strain, and time to failure with strain rates are established and expressed using the power law function to describe the fatigue life. Fractured specimens undergo metallography examination using an electron microscope, and fractography is discussed to differentiate the impact of SSRT on the physical damage characteristics under LCF loadings. LCF resistance of Alloy 617 is found to be time-dependent. Based on the results, it is recommended that the factor of safety must be considered in the designing phase to evaluate the fatigue life.
