Iron and Steel Materials Lab
Machine-translated · View original
A lab studying nitrogen-containing steels and phase transformations in steel.
AboutAbout the lab
Tackling iron and steel with nitrogen, high magnetic fields, and low temperatures.
The Iron and Steel Materials Lab (Koyano Lab) studies iron and steel materials, including nitrogen steel, which is iron with nitrogen added.
As the only iron and steel materials lab at the University of Tsukuba, it has four keywords: nitrogen, high magnetic fields, low temperatures, and collaborative research.
The lab is part of the Cryogenics Division of the Research Facility Center for Science and Technology, and it carries out its research using the division's low-temperature measurement equipment and gas-related facilities and expertise.
The lab accepts graduate students only if they are fluent in Japanese, have earned credits in solid-state physics and quantum mechanics, and come from a materials-related department.
Key terms
- Nitrogen steel
- Steel made by adding nitrogen to iron. If made well, it becomes strong, rust-resistant steel.
- Martensitic transformation
- A type of change in crystal structure (phase transformation) that occurs in steel. It is a first-order phase transition that releases a large amount of heat.
- High magnetic field
- A strong magnetic field. It is used to adjust the driving force of a phase transformation without changing the temperature.
ResearchResearch themes
Iron and steel are materials that support everyday life, and the accumulated knowledge and technology on iron and steel is vast. Using nitrogen, high magnetic fields, and low temperatures as its approaches, the lab develops nitrogen steels and investigates the mechanisms of phase transformations in steel.
*Illustrative imageDeveloping inexpensive, eco-friendly high-nitrogen steel
Steel containing nitrogen is inexpensive, strong, suitable for recycling, and resistant to rust. The lab works on fabrication methods and property evaluation for high-performance nitrogen steels. Together with a lab at Kyushu University, it studies isothermal transformation in order to establish heat-treatment guidelines needed for practical use.
*Illustrative imageWhy transformations in steel do not depend on time
Unlike ordinary first-order phase transitions, the martensitic transformation in most steels does not depend on time. To find out why, the lab uses liquid helium and superconducting magnets to measure transformations at extremely low temperatures, where diffusion is suppressed.
*Illustrative imageResearch on titanium alloys
The lab joined the Cabinet Office's Cross-ministerial Strategic Innovation Promotion Program (SIP) "Structural Materials for Innovation," which began in fiscal 2014, and started measuring the physical properties of titanium-based structural materials and studying gas elements, an area in which it gained experience through nitrogen steel. It also does applied research on low Young's modulus alloys developed for biomedical use.
*Illustrative imageDeveloping low- and high-temperature measurement equipment
For the shared-use instruments MPMS and PPMS, the lab tries out unconventional ways of using them, such as building its own attachments. It also wants to build equipment for evaluating material properties that fall outside what these instruments can cover, such as mechanical properties, and it is applying that technology to build high-temperature experimental equipment.
