Creep and Creep-rupture Behavior of 2124-T851 Aluminum Alloy

High Temperature Materials and Processes, 2013
High temperature creep and useful creep life behavior of Al-Cu-Mg (2124-T851 aluminum) alloy was investigated by conducting constant stress uniaxial tensile creep tests at different temperatures (473–563 K) and at stresses ranging from 80 to 200 MPa.

Experimental and numerical analysis of initial plasticity in P91 steel small punch creep samples [PDF]

, 2017
To date, the complex behaviour of small punch creep test (SPCT) specimens has not been completely understood, making the test hard to numerically model and the data difficult to interpret.

The Relation between Creep Rupture Time and Minimum Creep Rate of Austenitic Stainless Steel

Journal of the Society of Materials Science, Japan, 1973
An attempt is made to explain the growth process of creep cavities wherein the diffusion mechanism is not applicable. When a screw dislocation reaches grain boundary, the dislocation starts to move on the different slip plane by cross-slip. But such movement of the dislocation is interrupted at a precipitated particle located near the grain boundary ...

Creep behaviour of as received, aged and cold worked INCONEL 617 at 850 °C and 950 °C [PDF]

, 2010
The effect of initial microstructure on alloy 617 creep behaviour has been investigated at 850 °C and 950 °C. The solution treated material shows non-classical creep behaviour at both temperatures with a strain rate drop at the beginning of the tests ...

A Numerical and Experimental Assessment of the Small Punch Creep Test for 316L(N) Stainless Steels

Metals, 2021
This paper presents a finite element analysis of the small punch creep test for 316L(N), which is compared with experimental data for 650 and 700 °C. Special emphasis is placed on (i) assessing the influence of friction and (ii) comparing two different ...

Creep rupture of materials: insights from a fiber bundle model with relaxation

, 2010
I adapted a model recently introduced in the context of seismic phenomena, to study creep rupture of materials. It consists of linear elastic fibers that interact in an equal load sharing scheme, complemented with a local viscoelastic relaxation ...

Analyzing the characteristics of the cavity nucleation, growth and coalescence mechanism of 9Cr-1Mo-VNb steel (P91) steel [PDF]

, 2013
Creep damage is one of the serious problems for the high temperature industries and computational approach (such as continuum damage mechanics) has been developed and used, complementary to the experimental approach, to assist safe operation.
