Ichikawa Lab
Machine-translated · View original
The lab explores the strength and reliability of materials through the high-speed deformation of particles.
AboutAbout the lab
From particle deformation to material reliability.
The Ichikawa Lab studies the safety and reliability of materials, and conducts research that leads to the development of materials that can be used for long periods at high temperatures.
Using cold spray, a coating and repair technology, the lab investigates how particles deform when they adhere.
By compressing particles under precisely controlled load and strain rate, it observes how oxide films break and how recrystallization proceeds inside the particles.
The lab's website is shared with the labs of Professor Ogawa, Assistant Professor Saito, and Assistant Professor He, and is published under the name "Ogawa-Saito/Ichikawa Lab."
Key terms
- Cold spray
- A technology that forms a coating by spraying metal powder onto a substrate at high speed in the solid state, without melting it
- Recrystallization
- A phenomenon in which new, low-strain crystal grains form inside a heavily deformed metal and replace its existing microstructure
- Strain rate
- A quantity that expresses how fast a material is being deformed
ResearchResearch themes
In cold spray, the deformation of particles plays an important role in how they adhere. Through experiments with precisely controlled load and strain rate, the lab investigates how the oxide film covering a particle breaks and how recrystallization proceeds inside it.
