The lab designs heat-resistant materials, such as those used in jet engines, starting from their microstructure.
AboutAbout the lab
Making heat-resistant materials for jet engines
The lab studies heat-resistant materials used in aircraft jet engines and similar applications.
By creating different microstructures inside materials through processing and heat treatment, it clarifies how mechanical properties at high temperatures arise.
The materials it works with include titanium alloys, shape memory alloys that recover their shape even at high temperatures, and high-entropy alloys.
It also aims to contribute to a circular society through material design that reduces environmental impact.
Key terms
- Microstructure
- The internal structure of a material, such as the size and arrangement of its crystal grains. It changes with processing and heat treatment.
- Creep
- A phenomenon in which a material gradually deforms over time when a force is applied continuously at a high temperature.
- Additive manufacturing
- A method of forming three-dimensional parts by solidifying material such as metal powder and stacking it layer by layer. It is done with metal 3D printers.
- Shape memory alloy
- An alloy that returns to its original shape when heated above a certain temperature, even after being deformed.

ResearchResearch themes
The lab studies heat-resistant materials used in aircraft jet engines and in gas turbines at thermal power plants. Focusing on titanium alloys and high-temperature shape memory alloys, it aims to improve mechanical properties at high temperatures by controlling the microstructure through processes such as forging.
*Illustrative imageHeat-resistant titanium alloys that make use of impurities
The lab investigates how oxygen and iron, which easily end up in recycled titanium, affect strength at high temperatures. It also carries out creep and fatigue tests, and works on designing heat-resistant materials that make use of oxygen and iron.
*Illustrative imageMaking heat-resistant materials by additive manufacturing
The lab makes materials from titanium alloy powder by additive manufacturing and investigates how the microstructures specific to this process affect mechanical properties at high temperatures. Recently, it has also been trying materials other than titanium alloys.
*Illustrative imageHigh-temperature deformation of high-entropy alloys
High-entropy alloys, which mix multiple elements in equal proportions, show high strength because their crystal structure is greatly distorted. The lab works on applying this feature to heat-resistant materials.
*Illustrative imageShape memory alloys that recover their shape at high temperatures
This research aims to make shape memory alloys, which normally recover their shape only at low temperatures, recover their shape at high temperatures as well. The lab is also working on predicting martensitic transformation temperatures with machine learning.
