RISStress Assisted Grain Boundary Oxidation Behavior of IN706 Material Used in Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The electric power sector is currently facing major industry challenges around decarbonization efforts, and gas turbines will continue to play a crucial role for the energy transition. Major efforts have included ...
Metallurgical Investigation and Failure Analysis in GTD-111 Stage 2 Buckets From an Industrial F-Class Gas Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A utility experienced cracking in multiple stage 2 buckets (S2Bs) in a large F-class power generation gas turbine after only 7348 h and 31 starts following a standard repair and rejuvenation heat treatment cycle. The blades ...
Assessing Creep–Fatigue Interactions in Wrought and LP-DED-Processed 316 Stainless Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examines the low-cycle fatigue (LCF) and creep–fatigue (CF) behavior of wrought 316L and 316H stainless steels to develop acceptance criteria for accelerated testing of additively manufactured (AM) stainless ...
Creep Analysis and Microstructural Evaluation of a Novel Additively Manufactured Nickel-Base Superalloy (ABD®-900AM)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nickel-base superalloys containing 30 to 50% gamma prime (γ') volume fraction are typically used in hot section components (e.g., guide vanes or blades) for power generating gas turbines, and suitable time-dependent ...
Review of the Impact of Hydrogen-Containing Fuels on Gas Turbine Hot-Section Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an effort to achieve worldwide decarbonization goals, a range of low-carbon fuels is being proposed for use in power-generation gas turbines. Two promising fuels are hydrogen and ammonia, which do not produce any CO2 ...
Options for Improving Performance of Additively Manufactured Nickel-Base Superalloys for Gas Turbine Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) has been increasingly used for gas turbine (GT) components over the last decade. Many different components can be successfully designed, printed, and used in the gas turbine. However, there still ...
Assessing Creep–Fatigue Interactions in Wrought and LP-DED-Processed 316 Stainless Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examines the low-cycle fatigue (LCF) and creep–fatigue (CF) behavior of wrought 316L and 316H stainless steels to develop acceptance criteria for accelerated testing of additively manufactured (AM) stainless ...
Meta-Analysis of Thermal Barrier Coating Lifetimes in High-Water Vapor Environments: Implications for High-Hydrogen Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Thermal barrier coatings (TBC) are used to protect hot-section components, including combustor liners, turbine blades and vanes, and shrouds in gas turbine hot sections. Because improvements in combined-cycle gas ...
Learnings in the Qualification of ABD®-900AM for Turbine, Aerospace, and Energy Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. ABD®-900AM is a highly printable, gamma prime strengthened superalloy purposely designed for powder bed fusion (PBF) additive manufacturing (AM) with broad applicability to high-temperature gas turbine, aerospace, ...
