“…The precipitate formation may be strategically manipulated through different thermomechanical processing routes and aging to yield beneficial properties. Recently, a collaboration comprising Swansea University, Oxford University and Rolls Royce has sought to gain a greater understanding of the relationship between the development of these precipitates (Simm et al, 2017;Gray et al, 2017) and the mechanical properties of the resultant steel.…”

1 This article will form part of a virtual special issue on advanced neutron scattering instrumentation, marking the 50th anniversary of the journal.QUOKKA is a 40 m pinhole small-angle neutron scattering instrument in routine user operation at the OPAL research reactor at the Australian Nuclear Science and Technology Organisation. Operating with a neutron velocity selector enabling variable wavelength, QUOKKA has an adjustable collimation system providing source-sample distances of up to 20 m. Following the largearea sample position, a two-dimensional 1 m 2 position-sensitive detector measures neutrons scattered from the sample over a secondary flight path of up to 20 m. Also offering incident beam polarization and analysis capability as well as lens focusing optics, QUOKKA has been designed as a general purpose SANS instrument to conduct research across a broad range of scientific disciplines, from structural biology to magnetism. As it has recently generated its first 100 publications through serving the needs of the domestic and international user communities, it is timely to detail a description of its asbuilt design, performance and operation as well as its scientific highlights. Scientific examples presented here reflect the Australian context, as do the industrial applications, many combined with innovative and unique sample environments. research papers J. Appl. Cryst.

“…The dominant strengthening factor is precipitate hardening by the intermetallic compounds [81], for example, fine Laves phase and β-NiAl in the novel maraging steel studied here [82][83][84][85]. Apart from precipitation, strong elements such as nickel have meltable sites, for example in enhancing hardenability.…”

Creep-resistant aeroengine shaft steels: Precipitates and consequences

Creep resistant steels must be stable over long periods of time under severe operating conditions. This paper reviews precipitation in Cr-Mo steels and maraging steels destined for elevated temperature applications. It also covers aspects of structural evolution, strengthening and degradation, all of which are essential for alloy design. Two classes of steels are emphasised, those with origins in the power generation industries, and a novel approach based on intermetallic precipitates.
