Strength System Design Lab
Machine-translated · View original
A metallic materials lab that designs alloys usable at 1500°C and alloys that are both lightweight and strong.
AboutAbout the lab
Creating alloys that withstand high temperatures and are light yet strong.
The Strength System Design Lab studies new metallic materials (alloys) that contribute to energy savings.
The lab develops heat-resistant alloys that can be used at temperatures above 1500°C, and alloys that are strong yet light, with a density less than one-third that of iron.
Through both experiments, including computation, and theory, the lab investigates the relationship between a material's properties and its internal microstructure, and between the microstructure and the alloy composition.
The lab aims to establish methods for designing microstructure and composition by tuning properties at each level of the hierarchy, from the nanoscale to the macroscale.
Key terms
- Microstructure
- Microstructure: the makeup of the inside of a metal, such as the size, shape, and arrangement of crystal grains and of other phases.
- Composition
- Composition: which elements an alloy contains and in what proportions.
- Molecular dynamics
- Molecular dynamics: a computational method that uses a computer to follow how many atoms move under forces, according to the laws of motion.

ResearchResearch themes
To realize energy savings, the lab develops heat-resistant alloys that withstand high temperatures and alloys that are light and strong. Through both experiments and computation, it aims to establish methods for designing the microstructure and composition of materials.
*Illustrative imageUltra-Heat-Resistant Alloys Based on Refractory Metals
These alloys withstand high temperatures at which conventional heat-resistant alloys based on iron or nickel would melt. Aiming at highly efficient power generation by gas combustion, the lab combines oxidation-resistant coatings with strengthening phases to improve their properties.
*Illustrative imageLightweight, Strong Mg and Al Alloys
The lab controls how slip occurs to improve the deformability of magnesium, and designs high-strength materials combined with a new strengthening phase (LPSO, long-period stacking ordered phase). It also conducts fundamental deformation experiments using single crystals, and works on making aluminum alloys with an excellent balance of strength and ductility by controlling nanoclusters and precipitates.
*Illustrative imageNew Steel Materials
By controlling the types of added elements and the conditions of processing and heat treatment, the lab obtains fundamental knowledge for making steel materials with excellent mechanical properties.
*Illustrative imageAtomic-Scale Simulation
Using methods such as molecular dynamics, which follows the motion of many atoms, and the Monte Carlo method, which imitates state changes governed by chance, the lab explores the physics behind the origin of material properties.
