  • A Field Dislocation Mechanics Approach to Emergent Properties in Two-Phase Nickel-Based Superalloys
    A Field Dislocation Mechanics Approach To Emergent Properties In Two-Phase Nickel-Based Superalloys By James Jordan Little A thesis submitted to the University of Birmingham for the degree of DOCTOR OF ENGINEERING School of Metallurgy and Materials College of Engineering and Physical Sciences University of Birmingham March 2019 University of Birmingham Research Archive e-theses repository This unpublished thesis/dissertation is copyright of the author and/or third parties.

Abstract The objective of this study is the development of a theoretical framework for treating the flow stress response of two-phase alloys as emergent behaviour arising from fundamental dislocation interactions. To this end a field dislocation mechanics (FDM) formulation has been developed to model heterogeneous slip within a computational domain representative of a two-phase nickel- based superalloy crystal at elevated temperature. A transport equation for the statistically stored dislocation (SSD) field is presented and implemented within a plane strain finite element scheme. Elastic interactions between dislocations and the microstructure are explicitly accounted for in this formulation. The theory has been supplemented with constitutive rules for dislocation glide and climb, as well as local cutting conditions for the γ0 particles by the dislocation field.

Memorial Tributes: Volume 20 ANTHONY KELLY 1929–2014 Elected in 1986 “For pioneering research in the development of strong solids and composite materials.” BY ARCHIE HOWIE SUBMITTED BY THE NAE HOME SECRETARY ANTHONY KELLY, a seminal figure in the development of composite materials and a reforming vice chancellor at the Uni- versity of Surrey, died on June 3, 2014, at the age of 85. Tony, as he was generally known, was born in Hillingdon, West London, on January 25, 1929. His father, Group Captain Vincent Gerald French Kelly, who was of Irish descent, taught mathematics to pilots in the education service of the Royal Air Force. Tony’s scientific promise became apparent at the age of 13 in Presentation College, Reading, when he successfully corrected a physics teacher’s work on the blackboard. Since Presentation College did not have a sixth form, he had to develop his own habit for intensive study and teach himself enough physics, chemistry, geography, and geology to take the University Intermediate Examination and win an open scholarship in science at the University of Reading. Tony’s doctoral research was carried out between 1950 and 1953 at the Cavendish Laboratory, Cambridge, in Sir Lawrence Bragg’s famous crystallography group. Although his formal supervisor was W.H. Taylor and he had intermittent guid- ance from Bragg, his main mentor was Peter Hirsch, who had been largely responsible for setting up the x-ray microbeam equipment and exploring its use to investigate the structure of deformed metals.

  • Sir Alan Howard Cottrell Scd, FRS, Freng, LLD (Hon) (17 July 1919 – 15 February 2012)
    Sir Alan Howard Cottrell ScD, FRS, FREng, LLD (Hon) (17 July 1919 – 15 February 2012) With the death of Sir Alan we have lost a scientific ‘Colossus’ in the field of materials science and metallurgy. Entering Birmingham University from Moseley Grammar School to read Metallurgy, Alan graduated in 1939 and obtained a PhD in 1942 for research in the field of steel welding, of significance in relation to tank armour. He was greatly influenced by the Head of Department, Professor David Hanson. Recognising Cottrell’s outstanding scientific ability, Hanson took him onto his staff with the remit of developing modern science concepts in both the teaching and research in the Birmingham Department, aided by Raynor from Oxford where the atomic theory of metals was being developed by Hume Rothery. Cottrell had then to teach himself the level of advanced physics unknown to a conventional metallurgist, which was necessary for the task that he had been set. This enabled him in his own research to take dislocation theory forward, to make it more quantitative, and to explain, for example, the phenomenon of the yield point and strain ageing in steel. At the early age of 30 he was appointed Professor of Physical Metallurgy, always showing an ability to present difficult subjects in a new and understandable way. Recognising a rising star, he was made Deputy Head of the Metallurgy Division at the AERE Harwell Laboratory in 1955 where it was becoming clear that a structural atomistic approach was necessary to understand and predict the behaviour of materials in modern reactors. In January 1958 he was approached by Lord Adrian, Vice Chancellor of Cambridge University, to take the Goldsmiths’ Chair of Metallurgy, vacant following the retirement of G P Wesley Austin.

MARSHALL 1932–1996 Elected in 1979 “Contributions to the technology and direction of nuclear energy programs and to the transfer of the technology to industry.” BY DAVID FISHLOCK AND L.E.J. ROBERTS SUBMITTED BY THE NAE HOME SECRETARY WALTER CHARLES MARSHALL died February 20, 1996, at age 63 in London. He was recognized by the scientific commu- nity at an early age as one of the outstanding theoretical physi- cists of his generation. But he is more likely to be remembered for his distinguished career in public service, which led to a knighthood in 1981 and a life peerage in 1985, and for his forth- right public advocacy of nuclear power. Early Years: Pure and Then Applied Scientist Walter Marshall was born March 5, 1932, in Rumney, near Cardiff, the youngest child of three. In later years, he delighted to recall that he had insisted on “doing sums” on his first day in primary school. His mathematical promise was recognized by his mathematics teacher, Mr. Wustenholme, in grammar school, St. Illtyd’s College in Cardiff. He also developed a seri- ous interest in chess at the age of 11 and became the Welsh Junior Chess Champion at 15. He left school with a major county scholarship in 1949 to study mathematical physics at the University of Birmingham, Adapted and reprinted with the permission of the Royal Society.

  • Harnessing Stochasticity Collection
    The Harnessing of Stochasticity Physiological and philosophical consequences Articles by Raymond and Denis Noble This pdf collection of 9 articles brings together a developing story. It can be seen as the culmination of many years of discussions between the two of us on the nature of biology, what causes what and how, and what evolves and how. Those discussions long predate the first articles to appear. The opening shot in print was the 2012 formulation in Interface Focus of the mathematical basis of the principle of biological relativity, meaning relativity of causation by different levels of organisation ganisms in or , which had already been implied in The Music of Life (2006). That principle is insufficient on its own since there has also to be a specific process by which lower level processes are constrained by higher-­‐level organisation. The beginnings of identifying that process as including the harnessing of stochasticity occurred at the 2016 meeting at The Royal Society on New Trends in Evolutionary Biology, published in Interface Focus in 2017. But that idea was not followed up in the Discussion Meeting itself, very except for a helpful chance meeting we had with the immunologist Richard Moxon during breakfast the next day. What really set discussion alight was the 2017 article in Biology, which was the subject of a very lengthy interaction -­‐ with a neo darwinist referee. That was followed by a cascade of invitations the for subsequent articles published in a variety of journals leading up to the Journal 2020 article in the for the General Philosophy of Science.
