ECCC TEST PROGRAMME AND DATA ASSESSMENT ON GTD111 CREEP RUPTURE, STRAIN AND DUCTILITY [PDF]

open access: yes, 2014
GTD111, a creep resistant Ni-based superalloy developed by GE, is widely used in land-based gas turbine first stage blades. However, there is little published information on its creep properties and microstructure.

Novel martensitic steel for ultra-supercritical power rotors: enhanced high-stress creep resistance via multi-element MC carbides

open access: yesMaterials Research Letters
This study presents the design of a novel heat-resistant steel derived from the P91 steel, achieved through precise control of C, Mo, V, and Cr contents, along with the addition of Ti and Ta.

Practical considerations of the use of cross-weld and compact tension specimens creep data [PDF]

open access: yes, 2016
This article gives an overview of the use of cross-weld and compact tension specimen modelling and analyses data to characterise creep behaviour of the high-temperature components. Cross-weld and compact tension specimens are used to describe creep crack

FE implementation of damage-coupled inelastic constitutive equation for P91 steel

open access: yesMechanical Engineering Journal
The objective of this study is to numerically evaluate the cyclic softening behavior and creep-fatigue damage of P91 steel. To achieve this, a damage-coupled inelastic constitutive equation is formulated by coupling the Chaboche-type viscoplastic ...

Determination of energy dissipation and process instability in various alloys on the basis of plastometric tests

open access: yesMetalurgija, 2013
Energy dissipation and areas of process instability were investigated in two alloys. The first one was brass, the second one was the steel 9 Cr (P91). The tests were performed on torsion plastometer Setaram and on compression plastometer Gleeble.
