The accelerated insertion of materials (AIM) initiative provides the opportunity to reduce the materials development cycle time by up to 50% and thereby lessen the lead time required for new materials and processes. The program was founded to revolut

It has been recently shown that microtwinning is the principal deformation mechanism under certain creep conditions in several polycrystalline nickel-base superalloys. A creep model based on this mechanism is developed in this paper. Model parameters

Creep deformation substructures in the superalloy Rene 88 DT have been investigated after small-strain (0.2–0.5%) creep at 650 °C using conventional and high resolution transmission electron microscopy. Clear differences in creep strength and defo

Empirical datasets of volume fractions and size distributions of small gamma' precipitates from "real" multi-component engineering nickel-based superalloys are vital to calibrate and validate the computer models which predict high sensitivities of me

Critical Grain Growth (CGG) in powder metallurgy nickelbased superalloys is defined as abnormally coarse grains growing in a region of critical strain or strain rate after heat treatment above the gamma prime solvus temperature. As these large grains
