Effect of Heat Treatment on Properties of INCONEL 617 Investigated in Accelerated Creep Testing

, 2017
An accelerated creep test was implemented to study the effects of heat treatment on the creep properties of INCONEL 617. Three heat treatment conditions were set on the test specimens, including 1) as-received, 2) aged as the simulation of service ...

Creep: time‐dependent brittle deformation in rocks

, 2009
The characterization of time‐dependent brittle rock deformation is fundamental to understanding the long‐term evolution and dynamics of the Earth’s crust. The chemical influence of pore water promotes time‐dependent deformation through stress corrosion

An Accelerated Creep Assessment Method Based on Inelastic Strain Partitioning and Slow Strain Rate Testing

, 2021
A new accelerated creep assessment method to evaluate the creep performance of metals and alloys from high-temperature tensile tests, i.e. slow-strain-rate testing (SSRT), is proposed and evaluated. The method consists of decomposing the inelastic strain

Microstructural evolution and creep mechanism of a directionally solidified superalloy DZ125 under thermal cycling creep

, 2023
In this study, thermal cycling creep tests under (950 °C/15 min+1100 °C/1 min)/100 MPa were performed to simulate the overheating service condition of a directionally solidified superalloy DZ125.

The effect of the through-thickness moisture content gradient on the moisture accelerated creep of paperboard: Hygro-viscoelastic modeling approach

, 2018
Paper-based materials are viscous materials, the time-dependent behavior of which depends strongly on moisture content. Particularly the creep of paperboard containers under compressive forces is greatly affected by changes in the relative humidity.

Evaluation of creep behavior of geosynthetics using accelerated and conventional methods [PDF]

, 2007
Geosynthetics are susceptible to creep, which leads to time-dependent strains and potentially induces deformation of the structural systems. In the design of geosynthetics, one of the major issues is to apply the appropriate creep reduction factors.
