The impression creep Monkman Grant relationship

Ubiquity Proceedings, 2018
Impression creep testing is an established small-scale testing technique in which the indentation rate of a rectangular indenter can be converted into equivalent creep strain rate.

Based on damage caused by microstructure evolution during long-term thermal exposure to analyze and predict creep behavior of Ni-based single crystal superalloy

AIP Advances, 2020
The creep rupture life of a Ni-based single-crystal superalloy was evaluated under 980 °C/270 MPa after the superalloy was thermally exposed to temperatures of 900 °C, 950 °C, and 1100 °C for 100 h–500 h.

Effect of weld angle on the creep rupture life of ferritic/austenitic dissimilar weld interfaces under remote mode I fracture

Engineering Fracture Mechanics, 2019
Dissimilar metal welded structures (DMWs) used extensively in conventional and nuclear power plants can suffer from in-service failures at the dissimilar interface with a much reduced life compared to similar metal weld counterparts at the same operating

Creep behavior and cavitation evolution of 15CrMoG steel at high temperatures

Advances in Mechanical Engineering, 2019
15CrMoG steel is a type of heat-resistant steel frequently used in boiler and piping systems. Creep properties of the 15CrMoG steel at service temperatures are not much documented due to the difficulties in obtaining long-term creep data.

Creep Rupture Life Prediction of High Temperature HRSG Tubes [PDF]

Journal of the Korean Society of Safety, 2013
Abstract : The Heat Recovery Steam Generator(HRSG) is a device recycling the exhaust gas of gas turbine in combined power and chemical plants. Since service temperatures was very high, the damage of HRSG tubes intensively occurred in superheater and reheater.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Machine learning augmented predictive and generative model for rupture life in ferritic and austenitic steels

npj Materials Degradation, 2021
The Larson–Miller parameter (LMP) offers an efficient and fast scheme to estimate the creep rupture life of alloy materials for high-temperature applications; however, poor generalizability and dependence on the constant C often result in sub-optimal ...
