The effect of thermal cycling on the high-temperature creep behaviour of a single crystal nickel-based superalloy [PDF]

open access: yes, 2007
Isothermal and thermal cycling creep behaviours of a single crystal nickel-based superalloy have been studied by means of tensile tests at 1150 °C and 80 MPa.

Beneficial Effect of Pt and of Pre-Oxidation on the Oxidation Behaviour of an NiCoCrAlYTa Bond-Coating for Thermal Barrier Coating Systems [PDF]

open access: yes, 2011
The oxidation behaviour of a thermal barrier coating (TBC) system is a major concern as the growth of the thermally grown oxide (TGO) layer on the bondcoating creates stresses that greatly favour the thermal barrier spallation.

Segmentation and Measurement of Superalloy Microstructure Based on Improved Nonlocal Block

open access: yesIEEE Access, 2022
The microstructure of superalloy materials has a decisive impact on its service performance. When preparing the material and photographing the microstructure, different depths of metallography perpendicular to the cut plane appear in the microstructure ...

Mechanisms of High Temperature Degradation of Thermal Barrier Coatings. [PDF]

open access: yes, 2009
Thermal barrier coatings (TBCs) are crucial for increasing the turbine inlet temperature (and hence efficiency) of gas turbine engines. The thesis describes PhD research aimed at improving understanding of the thermal cycling failure mechanisms of ...

Effect of Pre-Post TIG Welding Heat Treatment on Cast NI Superalloy

open access: yesAnnals of "Dunarea de Jos" University of Galati, Fascicle XII, Welding Equipment and Technology, 2020
The effect of a pre (before) and post (after) heating welding treatment on the microstructure and mechanical properties of the scrap blades made of cast INC738LC superalloy is the main goal of the present investigation. The filler used in TIG welding was
