Materials Science and Technology is an international forum for the publication of refereed contributions covering fundamental and technological aspects of materials science and engineering. It has a particular interest in the continuum from understanding of process routes leading to the generation of microstructure, through characterisation and understanding of how microstructure is controlled and manipulated, to the control and prediction of relevant engineering properties.

Creep Deformation, Damage and Thermal-Mechanical Fatigue Analysis for High Temperature Materials and Welds

W Sun, A A Becker & T H Hyde

This special issue presents a collection of articles from the Dural Conference, which focuses on some recent advances on creep, fatigue, damage and fracture analysis of high temperature material and welds.

The issue includes research papers involving both original research and industrial experience. A wide range of topics is covered including: finite element failure and crack growth modelling of welds using creep continuum damage models; creep deformation, rupture and ductility of weld metals; and thermal-mechanical fatigue analysis for power plant steels using visco-plasticity models.

This issue is due to publish in early 2014.

Hardness across the multi-scales of structure and loading rate

R Armstrong, D Bahr, N Thadani & S Walley

This special issue of MST consists of twenty-three papers on the theme of hardness from both theoretical/modelling and experimental viewpoints. Coverage has been designed specifically to address a wide range of length scales, from macro to nano, and loading rates from highly instrumented nano-indentation to those characteristic of ballistic impact.

The issue has had a long gestation beginning when Ron Armstrong communicated with John Knott in late 2009 about doing an MST special issue on the topic. The suggestion was that it might be useful to propose a symposium on the topic in order to test focused interest in the subject in the materials community. Stephen Walley expressed interest in participating, in continuation of the long-standing activity initiated by David Tabor on hardness at the Cavendish Laboratory. David Bahr and Naresh Thadhani then put forward a proposal to TMS, on behalf of the four of us, to hold such a symposium at MS&T 2011 with the intention of publishing offered papers after normal review in an MST focus issue. Emphasis was given to the effort being a joint US (TMS) and UK (IOM3) activity.

The symposium covered indentation hardness testing methods and results for nano-, micro- and macro-scale investigations of crystal, polycrystal, polyphase structures spanning the same dimensional scales of structure, as well as amorphous materials. It also included loading rate considerations from essentially static to dynamic impact conditions.

Nanoengineering in the Modern Steel Industry

F G Caballero & C Capdevila

Steel is frequently the gold-standard against which emerging structural materials are compared. What is often not realised is that this is a moving standard, with notoriously regular and exciting discoveries being made in the context of iron and its alloys. Currently, there is a growing awareness of the potential benefits of nanoengineering in the modern steel industry, and a number of leading research and development institutes and companies are pursuing research in the area of nanostructured steels. In steels, the term ultrafine grain is used for average grain sizes between 1 μm and 2 μm in diameter. The term submicron structure refers to grain sizes between 100 nm and 1000 nm; and until recently effective processing techniques to reduce the grain size of these materials to less than 100 nm do not exist.

There are major difficulties in creating novel nanostructures that have a combination of properties appropriate for large scale applications. An important requirement is to be able to manufacture nanostructured components which are large in all dimensions. In addition, the material concerned must be cheap to produce if it is not to be limited to niche applications. Severe deformation by methods such as mechanical milling, equal channel angular processing and high pressure torsional straining has not succeeded in this respect. Although mechanical milling and alloying can produce powders containing nanosized grains, grain growth cannot effectively be suppressed during consolidation processes such as sintering and hot pressing. Therefore, processing bulk nanoscrystalline materials for structural applications stillposes a big challenge, particularly in achieving an industrially viable process. The purpose of this special issue is to describe various processing strategies and alloy developments currently being explored in the modern steel industry that have the potential to create extremely strong and affordable nanostructured engineering steels.
