Journal ArticleDOI
The role of interfacial dislocation networks in high temperature creep of superalloys
TL;DR: In this article, the dislocation networks generated during high-temperature creep of several single-crystal nickel-based superalloys are analyzed and the role of these networks in directional coarsening processes is studied, along with their formation kinetics, characteristics and stability during creep.
Journal ArticleDOI
Microstructure and tensile properties of Fe-40 At. pct Al alloys with C, Zr, Hf, and B additions
TL;DR: In this paper, the influence of small additions of C, Zr, and Hf, alone or in combination with B, on the microstructure and tensile behavior of substoichiometric FeAl was investigated.
Journal ArticleDOI
The effect of temperature on the
TL;DR: The tensile stress-strain behavior and failure mechanisms of a SiC/Ti-24Al-11Nb composite with continuous SCS-6 fibers oriented parallel to the loading direction have been examined over a range of temperatures from 23 °C to 815°C in air as mentioned in this paper.
Journal ArticleDOI

TL;DR: A cooperative program between the National Aeronautics and Space Administration (NASA), the Austrian Space Agency (ASA), Pratt & Whitney, Engineering Evaluation and Design, and Plansee AG was undertaken to determine the feasibility of achieving significant weight reduction of hypersonic propulsion system structures through the utilization of TiAl as mentioned in this paper.
Journal ArticleDOI
Fretting wear of Ti-48Al-2Cr-2Nb
TL;DR: In this paper, the wear behavior of gamma titanium aluminide (Ti-48Al-2Cr-2Nb in atomic percent) in contact with a typical nickel-base superalloy under repeated microscopic vibratory motion in air at temperatures from 296-823 K was examined.
