Yixiang to Attend Postgraduate Ferrous Metallurgy Symposium

Fri, 12 January, 2024

Yixiang Jin, a PhD student at NSIRC, is set to present his research on environmental cracking of additively manufactured materials at the upcoming 7th Postgraduate Research Symposium on Ferrous Metallurgy 2024.

The one-day conference, organised by the Materials Processing Institute, has the support of the Armourers & Brasiers’ Company and the IOM3 Iron & Steel Group. The symposium will be held on 27th Feb 2024 at Armourers’ Hall, Armourers & Brasiers’ Company, London, UK.

Aimed at individuals involved in materials, metals, and process improvement, the symposium provides a platform for universities, researchers, and businesses to learn about the latest developments in ferrous metallurgy. The event will feature presentations by PhD and EngD students, highlighting their research in the ferrous sector. Additionally, industry experts will be delivering keynote speeches, and there will be an exhibition and poster display.

Yixiang Jin is a PhD student at NSIRC, and his research project is supported by The University of Southampton, Lloyd's Register Foundation and TWI Ltd. He has a background in materials and chemistry and holds an MSc(Eng) degree in Aerospace Materials from the University of Sheffield. His research focuses on the environmental cracking of additively manufactured materials, which is a critical area of study in the field of ferrous metallurgy.

Examination of Environmental Cracking in Additively Manufactured Materials

Additive Manufacturing (AM) technologies are rapidly maturing, but environmental cracking behaviour remains largely unknown. Environmental cracking mechanisms are insidious failure mechanisms and occur where a susceptible microstructure is combined with a corrosive environment and stress. This has the potential to lead to catastrophic failure and loss of life.

Yixiang's research aims to establish whether AM materials behave similarly to traditional materials in terms of environmental cracking mechanisms, and therefore identify if standard approaches to prevent these failures are appropriate for AM components. The study is particularly significant as AM is becoming more commonly used in various industries, and there is a need to ensure that AM components are safe and reliable.

Moreover, hydrogen is going to be a renewable energy of the future and has the potential to replace fossil fuels in many ways. Today, there is a growing interest in research that explores the storage of hydrogen, as hydrogen atoms may enter the alloy and lead to the degradation of mechanical properties, known as hydrogen embrittlement. 316L stainless steel (SS) can be employed as high-pressure or liquid hydrogen containers due to its good low-temperature performance and high corrosion resistance. However, the influence of additive manufacturing on the hydrogen embrittlement of 316L SS is still unclear.

Yixiang's research is expected to provide valuable insights into the environmental cracking and hydrogen embrittlement of additively manufactured materials and shed light on how these materials can be made safer and more reliable.

Engaging with Yixiang's research can help businesses and researchers stay up-to-date with the latest developments in ferrous metallurgy and ensure that their components are safe and reliable. Email to put in touch with Yixiang directly, or you can find him on LinkedIn.
