Characterization of the cyclic softening and remaining creep behaviour of P92 steel weldment

open access: yesJournal of Materials Research and Technology, 2021
Different micro-regions of weldment are expected to present various cyclic softening behaviours during creep–fatigue interaction (CFI), which has a significant influence on the remaining mechanical properties.

High Temperature Mechanical Constitutive Modeling of a High-Nb TiAl Alloy

open access: yesJournal of Aeronautical Materials, 2018
Uniaxial tensile, low cycle fatigue, fatigue-creep interaction and creep experiments of a novel high-Nb TiAl alloy (i.e. Ti-45Al-8Nb-0.2W-0.2B-0.02Y (atom fraction/%)) were conducted at 750℃ to obtain its tested data and curves.

Muscle Activity Adaptations to Spinal Tissue Creep in the Presence of Muscle Fatigue. [PDF]

open access: yesPLoS ONE, 2016
The aim of this study was to identify adaptations in muscle activity distribution to spinal tissue creep in presence of muscle fatigue.Twenty-three healthy participants performed a fatigue task before and after 30 minutes of passive spinal tissue ...

High-Temperature Creep-Fatigue Behavior of Alloy 617

open access: yesMetals, 2018
This paper presents the high-temperature creep-fatigue testing of a Ni-based superalloy of Alloy 617 base metal and weldments at 900 °C. Creep-fatigue tests were conducted with fully reversed axial strain control at a total strain range of 0.6%, 1.2 ...

Fatigue and creep analysis of the first row of turbine blades of microturbine TRI60 [PDF]

open access: yesمجله مدل سازی در مهندسی, 2017
In today's modern turbines, temperature of the first row of blades, which are said the hot zone of turbine, has been boosted up to1000℃. These blades should be work for long periods.

Creep-Fatigue Interaction in the AISI H11 Tool Steel [PDF]

open access: yesKey Engineering Materials, 2009
The effect of process parameters on the creep-fatigue behavior of a hot-work tool steel for aluminum extrusion die was investigated through a technological test in which the specimen geometry resembled the mandrel of a hollow extrusion die. Tests were performed on a Gleeble thermomechanical simulator by heating the specimen using joule’s effect and by ...

Physical-Mechanism Exploration of the Low-Cycle Unified Creep-Fatigue Formulation

open access: yesMetals, 2017
Background—Creep-fatigue behavior is identified as the incorporated effects of fatigue and creep. One class of constitutive-based models attempts to evaluate creep and fatigue separately, but the interaction of fatigue and creep is neglected.

Characterization of crack nucleation in TA6V under fretting-fatigue loading using the potential drop technique [PDF]

open access: yes, 2010
Crack initiation in a Ti-6Al-4V alloy was investigated experimentally in fretting fatigue conditions. A cylinder-plane geometry was used for the contact, and partial slip conditions were considered.

Creep–fatigue Interaction Testing [PDF]

open access: yes, 2001
Fatigue fives in metals are nominally time independent below 0.5 T(sub Melt). At higher temperatures, fatigue lives are altered due to time-dependent, thermally activated creep. Conversely, creep rates are altered by super. imposed fatigue loading. Creep and fatigue generally interact synergistically to reduce material lifetime.

Creep-fatigue life assessment of cruciform weldments using the linear matching method

open access: yes, 2013
This paper presents a creep-fatigue life assessment of a cruciform weldment made of the steel AISI type 316N(L) and subjected to reversed bending and cyclic dwells at 550C using the Linear Matching Method (LMM) and considering different weld zones.
