Materials Processing Institute plays a leading role in The 6th International ECCC Conference
The 6th International ECCC Conference starts today in Edinburgh, 22-24th of May 2023
This conference focuses on creep and fracture in high temperature components, particularly related to design & life assessment. The aim of the conference is to disseminate knowledge and identify future work area requiring attention from the high temperature research, design and standardisation communities.
ECCC 2023 brings together engineers and scientists from around the world to present and discuss research and developments in all aspects of creep behaviour of high temperature industrial materials and components.
Dr Peter Barnard, a Principal Researcher at the Materials Processing Institute is the Chairman of the ECCC Organising Committee who, with the support of IOM3, have ensured a full conference with over 100 papers covering a broad range of topics including superalloys, austenitics, fatigue, and creep-fatigue and modelling.
Additionally, the conference is running a Poster Session and Ehsan Rahimi, a Senior Researcher at the Institute has contributed the following poster:
Poster Title: Advanced Analytical Methodology for Rapid Assessment of Cleanliness

This poster is a result of ongoing work being carried out by Ehsan Rahimi, Tu Tran, Ian Challenor and Peter Barnard, all researchers at the Institute.
Poster Abstract
The mechanical properties of alloys, and, in particular creep performance, are heavily dependent upon the cleanliness of the alloy where deleterious inclusions can lead to premature failure. In alloys for fusion reactors cleanliness is even more critical where potential in-service activation of the steels may lead to the rejection of the steel prior to installation.
The Materials Processing Institute in collaboration with the University of Sheffield, European Technology Development Ltd, and the University of Warwick, are evaluating potential alloys that have higher performance at the temperatures above the limits of the current fusion alloys. The alloys were made at the Materials Processing Institute using vacuum induction melting (VIM).
In addition to the chemical composition, the cleanliness was initially evaluated using an in-house method for scanning electron microscopy (SEM). Furthermore, a new analytical method was also created for optical emission spectroscopy (OES) offering a rapid assessment of inclusion distribution. This method was verified against the SEM evaluation. The scope was determined for the future assessment.
This study offers a method development approach to streamline the chemical analysis and inclusion assessment of all alloys including those for fusion. In addition to a rapid and cost-effective evaluation, and minimal sample preparation, the method provides an analysis on a larger surface area that can be potentially used for rapid quality assessment.
