Abstract
It is known that Ni-based superalloys possess superior mechanical properties in high-temperature and high-pressure environments. One of the drawbacks of these alloys is their tendency to oxidize at high temperatures. Improving their oxidation properties and obtaining a fundamental understanding of the underlying mechanism of their oxidation behavior are critical for.....

DOI:
https://doi.org/10.3365/KJMM.2022.60.12.940
Abstract
In order to investigate the mechanical properties of the developed wrought γ'-hardened Ni-based superalloy, LESS alloy (Low Eta Sigma Superalloy), and to understand the deformation behavior, tensile tests were carried out from room temperature to 800oC in comparison with IN 740H alloy. Like other superalloys, the tensile properties of the.....

Abstract
The influence of trace amounts of sulfur (S) on the microstructural evolution, tensile and creep properties in directionally solidified (DS) Ni-based superalloy GTD-111 were systematically investigated. Doping of S in the range of < 1 to 154 ppm resulted in the formation of a Ti

Abstract
Nickel-based superalloys have excellent resistance to extreme environments such as high temperature and high stress and are used as materials for large gas turbines. In this paper, specimens were taken from a blade that had been used for a long time, and their life span was studied by analysis of microstructure......

Abstract
Microstructure evolution and the creep fracture characteristics of dissimilar welds between Ni-based superalloy Inconel 740H and High Cr ferritic steel Gr.92 were investigated. The dissimilar welds were fabricated by shielded metal arc (SMA) welding process with Ni-based austenitic Inconel 182 superalloy. Postweld heat treatment at 760
