Measurement of average phase elastic strains and load sharing in complex multiphase Hot Isostatically Pressed stainless steel alloys

Abstract: Rolls-Royce have developed a Co-free stainless steel hardfacing alloy for use in Pressurised Water Reactors called RR2450, produced using Hot Isostatic Pressing (HIP) as the manufacturing route. We have found that the RR2450 alloy develops a triplex austenite/ferrite/silicide matrix after HIPing. Precipitates in the form of Cr and Nb carbides are also present extensively. The silicide phase is a new phase in steel. Our research has shown that the presence of this phase is potentially an attractive aspect of this alloy since it has extremely high hardness. In order to better understand the deformation behaviour of this alloy and in particular, the evolution of phase specific elastic strains and the load sharing/transfer between the hard and soft phases in this alloy, we propose to carry out in situ compression tests at room temperature using the ENGIN-X neutron beamline.
