It is well known that Fe, Co and Ni are characterised by abnormally fast diffusivity in the hcp phase of Ti (α-Ti). Their diffusivity values are 10 5 times higher than self-diffusion data, which is atypical for vacancy-mediated diffusion yet too slo
Despite being a catalyst for progress, Materials Science and Engineering is relatively unknown as an undergraduate discipline in the UK. By analysing UK data published by the Universities and Colleges Admissions System (UCAS) and the United Kingdom's

The beneficial effect of Re on the creep strengthening properties in single crystal Ni-based superalloys is well known, albeit understanding the underlying mechanism is still an ongoing area of investigation. The microstructure in these alloys compri

Stronger and more resistant alloys are required in order to increase the performance and efficiency of jet engines and gas turbines. This will eventually require planar faults engineering, or a complete understanding of the effects of composition and

High-throughput quantum mechanics based simulations have been carried out to establish the change in lattice parameter and superlattice intrinsic stacking fault (SISF) formation energies in Ni3Al-based alloys using the axial Ising model. We had direc

Local chemical fluctuations in the vicinity of superlattice intrinsic stacking faults (SISFs) have been observed via high resolution energy dispersive X-ray spectroscopy (EDS) mapping in new single crystal Co- and CoNi-base superalloys containing γ

We do Density Functional Theory based total-energy calculations of the L12 phase in Co3X and Ni3X compounds, X being a transition metal element. The lattice parameters, magnetic moments and formation enthalpies are determined and compared with the av

The high-temperature mechanical properties of precipitate-strengthened advanced alloys can be heavily influenced by adjusting chemical composition. The widely-accepted argument within the community is that, under certain temperature and loading condi

A model is proposed for the variation of the yield strength of nickel-based superalloys as a function of chemical composition. Consistent with hardening theory, alloy strength is assumed to be proportional to the product of the anti-phase boundary (A
