Decreasing the carbon dioxide emissions of the power generation, metal, and transportation industries, which emit large quantities of greenhouse gas, is an urgent issue for achieving a low carbon society. Carbon dioxide emissions must be decreased through improved energy efficiency by improving the performance of heat-resistant materials that are used for power generation turbines, jet engines for airplanes, and other applications. To achieve this, ALCA aims to develop technologies to substantially improve the properties of these materials, such as their high-temperature strength, room-temperature resilience, oxidation resistance, as well as technologies for their production and heat-resistant coating.
In addition, other research subjects include establishing manufacturing technologies for high-strength and high-performance materials from recycled raw materials, in order decrease the energy consumption of recycling, and the creation of structure-control to realize high performance while decreasing the amount of rare metals to be added.
Furthermore, ALCA will develop innovative metal and ceramic materials for the manufacture of lighter and stronger materials, in order to produce lighter transportation equipment that consumes less energy.
