Scope Martensite remains a key phase in steels for diverse industrial applications, e.g. automotive, cryogenics, pressure vessels, etc. Despite the large body of research on the subject, a gap persists in understanding the relationships between the competing transformation phenomena that occur during processing (auto-tempering, low temperature tempering, transition carbides, twinning, etc.), the hierarchical microstructures that are produced, and properties, including damage evolution in service.

The advent of advanced characterization techniques in recent years, in concert with modelling approaches, have provided fresh views on the austenite to martensite transformation, on martensite structure and chemical variations, and on its evolution during processing. The knowledge acquired has given new insights into the development of novel microstructure-property relationships.

It seems timely to provide a status on these investigations in a dedicated symposium with the aim of narrowing the gap in our understanding of microstructural evolution and its impact on properties. This Symposium will focus mainly on recent developments in the study of martensite in steels.

Abstracts are of interest (but not limited to) the following topics:

• Observations of new phenomena and microstructural evolution during quenching and tempering, service, and/or extreme environments
• Advanced characterization (development of new techniques and methods), as applied to martensite in steels
• Recent advances in multi-scale modeling of microstructure development during processing
• Microstructure-inclusive modeling of properties and performance
