The ISIJ will hold the international organized sessions during the 188th meeting to meet the necessity of globalization in the science and technology of iron, steel and other materials. In this session, the official language is English. The ISIJ welcomes participants from Japan and abroad to present papers at the International Organized Sessions focusing on current topics. All abstracts of presentations are published as Current Advances of Materials and Processes (CAMP-ISIJ), Vol.37 (2024) No.2.

International Organized Session Topics:

Session A: Microstructures and properties of iron ore sinters
Chairpersons: M. Hayashi (Tokyo Tech.), R. Murao (Nippon Steel)

The demand for carbon-neutral steelmaking as well as the inferior quality of iron ore have led to the necessity for designing high-quality iron ore sinters. To produce high-quality sinters with high pulverization resistance and high reducibility, it is important to investigate the crystal structure, morphology, and phase equilibria of multicomponent calcium ferrite (SFCA series), which are the main constituent phases of sinters, and to elucidate the relationship between the microstructures of sinters and their properties. In this international session, recent results on the above issues will be presented.

Session B: Realization and challenges of building a sustainable society through utilization of iron and steel slag
Chairpersons: H. Matsuura (The Univ. of Tokyo), Y. Uchida (Nippon Institute of Tech.)

Since the quality and quantity of iron and steel slag are stable, it is a valuable material in Japan where natural resources are scarce. This session will provide an opportunity for lectures and discussions to share the current status of the utilization of iron and steel slag, and other by-products in Japan and other countries. Furthermore, changes in the environment surrounding iron and steel slag in response to the trend toward decarbonization and carbon neutrality, which are pressing issues in the steel industry, will be discussed.

Session C: Innovative evaluation techniques for hydrogen entry and hydrogen trapping – IV
Chairperson: K. Fushimi (Hokkaido Univ.)

Along with the development of materials resistant to hydrogen embrittlement, standardization of hydrogen charging methods and deepening new evaluation techniques of hydrogen absorption based on hydrogen embrittlement that occurs in practical environments are important in considering measures against hydrogen embrittlement. In this session, recent developments in hydrogen absorption and trapping evaluations will be discussed from various perspectives.
