Joining Microstructure Evaluation Lab
Machine-translated · View original
The lab evaluates and predicts the microstructure and reliability of welded and joined parts.
AboutAbout the lab
Foreseeing joint reliability from joint microstructure.
The Joining Microstructure Evaluation Lab studies the properties of welded and joined regions from the standpoint of materials science.
It aims to understand the solidification and transformation behavior of materials and to clarify how microstructures form in welds and joints.
To evaluate and predict the reliability of joints, such as corrosion resistance and mechanical properties, as well as their service life, the lab carries out research using experiments and simulation.
The lab is a research field of the Joining and Welding Research Institute, Osaka University, and is also introduced in the Graduate School of Engineering under the name “Joining Microstructure Design Chair.”
Key terms
- Solidification and transformation
- Solidification is the change of a material from liquid to solid; transformation is the change of its internal microstructure after it has become solid.
- Corrosion resistance
- The ability of a material to withstand rust and corrosion.
ResearchResearch themes
To make the most of the properties and functions of materials, the lab aims to evaluate the properties of welded and joined parts with high accuracy, to clarify the factors that govern those properties, and to build technologies to control and predict them. Education and research are carried out from the standpoint of materials science.
