Characterisation of the gamma prime precipitate distribution in an advanced N...
The excellent high temperature properties of Ni-base superalloys are derived from the presence of fine precipitates of the intermetallic Ni3Al phase, termed gamma prime. The... -
Inter-phase load partitioning in a directionally-solidified Cr-Cr3Si eutectic
In situ composite materials based upon refractory metal - silicide eutectics are being considered for high temperature structural applications. These materials derive their high... -
Monitoring Gamma Prime Evolution in Superalloys using Small Angle Neutron Sca...
The aim of the experiment is to monitor the temporal evolution of gamma prime precipitates in three polycrystalline nickel base superalloys using Sans2D. This instrument is... -
Effect of alloying on the misfit of Ni-Ni3Al-Ni3V alloys
Ni-base superalloys have long been used in high temperature applications, including the high-demand environments of the high pressure turbines in jet engines. The remarkable... -
The Effect of Dilution on Residual Stresses In Multi-pass Welds Using Low Tra...
The aim of this experiment is to characterise the effect of dilution on the residual stresses in multiple-pass welds produced with specially designed filler alloys that exploit... -
Structural Phase Characterisation of Iron Stone Objects from the Excavation s...
We propose to determine the mineral phase composition in 15 iron stone samples from the Tall Bazi excavation site in Syria. The results of this investigation will be compared... -
Hysteresis in the deformation of layered crystal structures
The aim of this proposal is to study the origin of the hysteresis effect in many layered crystal structures, in particular MAX-phases, such as Ti2AlC. This effect has been... -
Effect of alloying on the misfit of Ni-Ni3Al-Ni3V alloys
The exceptional high temperature mechanical properties of Ni-base superalloys has resulted in their widespread use in high temperature applications. These alloys conventionally... -
Structural Phase Characterization of Iron Stone Mesopotamian Objects from the...
Mesopotamian iron oxide objects in the form of Roll seals and Weight are typical for the Old Babylonian Period (ca. 2000-1600 B.C.). In the museums they are usually cataloged as... -
Non-uniform elastic deformation of layered crystal structures
The aim of the experiment is to determine the relative compressibility of the structural layers in three 211 MAX phases (Ti2AlC, Ta2AlC and Cr2AlC) using the PEARL-HiPr beam... -
Reduced Residual Stresses In Multipass Welds Using Low Transformation Tempera...
The aim of this experiment is to characterise the residual stresses that evolve as a multiple pass weld is built up, while exploiting transformation plasticity due to specially... -
Non-uniform elastic deformation of layered crystal structures
The experiment will resolve a discrepancy between earlier experiments carried out very recently by us and work elsewhere on the hydrostatic compression of a series of 211... -
Characterisation of superalloys strengthened by Co3Ti
One method by which the efficiency of gas turbine engines may be improved is by increasing the gas stream temperature on entry to the turbine. Currently this temperature is... -
Misfit and Misfit Release in Co-Co3(Al,W) Superalloys
The effect of alloying additions (Ni, Fe, Cr, Ta, Mo, V, Ti, Si) on the misfit of developmental Co-Al-W alloys will be examined using Polaris. The Co3(Al,W) precipitate phase...
