Abstract Intermittent mechanical loads combined with high temperatures appear during the operation of turbines in jet engines or power plants, which can lead to high-temperature fatigue thermomechanical fatigue. Since assessment properties is a complex and time-consuming process, it essential develop validated material models that are capable predicting behavior, thus allowing extrapolation exp...

Multilayer thermal barrier coatings (TBCs) deposited on superalloy turbine blades provide protection from combustion temperatures in excess of 1500 1C. One of the dominant failure modes comprises cracking from undulation growth, or rumpling, of the highly compressed oxide layer that grows between the ceramic top coat and the intermetallic bond coat. In this paper, a mechanistic model providing ...

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

Abstract In industrial gas turbine (IGT) engine manufacturing, nickel-based superalloys are used mainly to meet the needs of components hot pathway. Although these alloys have high-temperature capabilities, parts prone damage during service. The high working temperatures engines lead component degradation due creep, fatigue, and oxidation reactions; therefore, cost newly produced superalloy com...
