A lab that creates new environmentally friendly high-temperature materials.
AboutAbout the lab
Advanced high-temperature structural materials with excellent environmental performance
The Terada Lab researches the development of new high-temperature materials that are environmentally friendly and contribute to human society.
Its work ranges from basic research investigating the scientific principles of high-temperature deformation to applied development research, including expansion into the environment and energy field.
By controlling the microstructure of materials such as magnesium alloys and Ni-based superalloys, the lab aims for materials that remain strong even at high temperatures.
It is a small lab where each student has an independent research topic and carries out research while discussing it with the faculty.
Key terms
- Creep
- A phenomenon in which a material slowly deforms when force is applied to it continuously at high temperature
- Precipitation
- The appearance of a phase different from the parent crystal, as grains or plates, inside an alloy
- Superalloy
- An alloy mainly composed of nickel or similar metals, made to retain its strength even at high temperatures
ResearchResearch themes
The lab conducts academic research to clarify the mechanisms of deformation and strengthening of materials at high temperatures. Based on these scientific principles, it is developing new high-temperature metallic materials for use in the environment and energy field.
*Illustrative imageCreating ultra-high-temperature materials through heterophase interface strengthening
The lab devised a new strengthening mechanism for high-temperature materials, which it named “heterophase interface strengthening.” To maximize the strengthening effect, it controls the microstructure into submicron-scale layers and applies this to alloys with high melting points, aiming to develop new ultra-high-temperature materials.
*Illustrative imageHigh-temperature deformation of heat-resistant magnesium alloys
The lab investigates the high-temperature deformation behavior of flame-retardant, high-strength heat-resistant magnesium alloys. In the Mg-Al-Ca system, the main strengthening mechanism is “coating strengthening” by the eutectic phase, in which the C36 phase covers the areas near dendrite boundaries and increases the fraction of the core region.
*Illustrative imageHigh-temperature strength of wrought Ni-based superalloys
Using a Ni-Cr solid solution that imitates the γ matrix phase, the lab clarified the principle of creep strengthening. Following the approach of raising both the strength of the core and the fraction of the core, it is working to increase the strength of wrought Ni-based superalloys.
*Illustrative imageMicrostructure design of alloys for thermal power plants
In alloys for advanced ultra-supercritical thermal power plants, the lab investigates the process by which intermetallic phases that are stable at high temperatures precipitate and coarsen. Using carbon-free alloys, it identified the temperatures at which the γ'' phase, δ phase, and C14-Fe2W phase precipitate readily.
