Alison Jean Davenport OBE CEng is the Professor of Corrosion Science at the School of Metallurgy and Materials, University of Birmingham.

Contents

Education

Davenport studied the Natural Sciences Tripos at the University of Cambridge [1] where she was a member of King's College, Cambridge. [2] She remained there for her graduate studies, earning her PhD in 1987. [3] [1] Her PhD was in metallurgy, investigating the oxide layers that form on top of metals. [3] [4]

Research and career

Davenport spent eight years as a staff scientist at Brookhaven National Laboratory, looking at synchrotron X-Ray techniques for corrosion and passivation of alloys.[ citation needed ]

In 1995 Davenport joined the University of Manchester. She was Associate Editor of the Journal of the Electrochemical Society between 1995 and 1997. [1] She has carried out several experiments at the Diamond Light Source and is a member of the I18 working group. [1] She was appointed to at the University of Birmingham and looked at the relationship between alloy microstructures and localised corrosion chemistry. [5] She developed X-Ray micro-tomography to study the growth of small cracks, allowing her to understand the transition from pits to cracks in metals. [6] She studies the relationship between microstructure and corrosion in stainless steel, titanium and aluminium. [7] She looked at the impact of grain boundary crystallography on intergranular corrosion. [7]

Davenport uses X-Ray imaging to study corrosion. [8] This information informs life-time prediction models. [8] She works with synchrotron facilities to develop in situ characterisation techniques to understand the mechanisms of corrosion. [9] Davenport leads an Engineering and Physical Sciences Research Council (EPSRC) consortium to develop synchrotron methods to look at nuclear waste storage. [10] [4] She has served as an international consultant on nuclear waste storage. [10] She collaborated with Owen Addison on how corrosion impacts biomedical implants. [4] [11] Her group monitor the atmospheric corrosion of stainless steel alloys and have found that morphology is very sensitive to relative humidity and residual ferrite. [12] [13] [14] They identified how bipolar plates corrode in proton-exchange membrane fuel cells. [15]

Awards and honours

In 2003 Davenport won the NACE International H. H. Uhlig Award for outstanding efforts in corrosion education. [16] In 2008 she chaired the Gordon Research Conference in aqueous corrosion. [17] She was made a member of the Innovate UK Advanced Materials Leadership Council and the Government of the United Kingdom expert group on materials science. [18] She was appointed a professor at the University of Birmingham in 2015. [4] In 2016 she delivered the Birmingham Metallurgical Association lecture. [19] She is on the working group of the Collaborative Computational Project in Tomographic Imaging. [20] She is part of the Institute of Materials, Minerals and Mining and is involved with their women in materials science activities. [21]

She was the Head of School of Metallurgy and Materials at the University of Birmingham (2016-2022).

Davenport was appointed Order of the British Empire (OBE) for services to electrochemistry in the 2018 Birthday Honours. [22] [23] [24]

<span class="mw-page-title-main">Galvanization</span> Process of coating steel or iron with zinc to prevent rusting

Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of hot, molten zinc.

<span class="mw-page-title-main">Stainless steel</span> Steel alloy resistant to corrosion

Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.

<span class="mw-page-title-main">Corrosion</span> Gradual destruction of materials by chemical reaction with its environment

Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion.

Passivation, in physical chemistry and engineering, refers to coating a material so it becomes "passive", that is, less readily affected or corroded by the environment. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build by spontaneous oxidation in the air. As a technique, passivation is the use of a light coat of a protective material, such as metal oxide, to create a shield against corrosion. Passivation of silicon is used during fabrication of microelectronic devices. In electrochemical treatment of water, passivation reduces the effectiveness of the treatment by increasing the circuit resistance, and active measures are typically used to overcome this effect, the most common being polarity reversal, which results in limited rejection of the fouling layer.

<span class="mw-page-title-main">Hydrogen embrittlement</span> Reduction in ductility of a metal exposed to hydrogen

Hydrogen embrittlement (HE), also known as hydrogen-assisted cracking or hydrogen-induced cracking (HIC), is a reduction in the ductility of a metal due to absorbed hydrogen. Hydrogen atoms are small and can permeate solid metals. Once absorbed, hydrogen lowers the stress required for cracks in the metal to initiate and propagate, resulting in embrittlement. Hydrogen embrittlement occurs most notably in steels, as well as in iron, nickel, titanium, cobalt, and their alloys. Copper, aluminium, and stainless steels are less susceptible to hydrogen embrittlement.

<span class="mw-page-title-main">Pitting corrosion</span> Form of insidious localized corrosion in which a pit develops at the anode site

Pitting corrosion, or pitting, is a form of extremely localized corrosion that leads to the random creation of small holes in metal. The driving power for pitting corrosion is the depassivation of a small area, which becomes anodic while an unknown but potentially vast area becomes cathodic, leading to very localized galvanic corrosion. The corrosion penetrates the mass of the metal, with a limited diffusion of ions.

The Institute of Materials, Minerals and Mining (IOM3) is a UK engineering institution whose activities encompass the whole materials cycle, from exploration and extraction, through characterisation, processing, forming, finishing and application, to product recycling and land reuse. It exists to promote and develop all aspects of materials science and engineering, geology, mining and associated technologies, mineral and petroleum engineering and extraction metallurgy, as a leading authority in the worldwide materials and mining community.

Michael A. Streicher was an American metallurgist and engineer who became internationally recognized for his work on the testing and development of corrosion-resistant stainless steel alloys. He published widely in technical journals and textbooks and received numerous patents for his inventions.

Corrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to design and implement materials, structures, devices, systems, and procedures to manage corrosion. From a holistic perspective, corrosion is the phenomenon of metals returning to the state they are found in nature. The driving force that causes metals to corrode is a consequence of their temporary existence in metallic form. To produce metals starting from naturally occurring minerals and ores, it is necessary to provide a certain amount of energy, e.g. Iron ore in a blast furnace. It is therefore thermodynamically inevitable that these metals when exposed to various environments would revert to their state found in nature. Corrosion and corrosion engineering thus involves a study of chemical kinetics, thermodynamics, electrochemistry and materials science.
