英文要約Title: Innovative Structural Materials Project (Future Pioneering Project) (FY2014-FY2017) FY2016 Annual Report

(1) Development of Joining Technology
In the joining technology of medium and high carbon steel plate, the appropriate power supply conditions were clarified for the resistance spot welding.

(2) Development of innovative titanium materials
We examined the effect of the rolling conditions on the porosity of a thin plate. In the titanium material consistent manufacturing process technology development, we considered the oxygen content for de-acid refining conditions to 300ppm or less by the thermodynamic study resulting in validation of the world's first dissolved de-acid technology.

(3) Development of innovative aluminum materials
In the development of high strength and high toughness aluminum alloy: for the alloy composition determined in 2014, properties were determined with examining necessary characteristics (strength, ductility, fracture toughness, SCC resistance).

(4) Development of innovative magnesium materials
In order to link the results of material development / joining technology etc. to industrial level product design and manufacture, we made prototype small components (side panels) of high speed vehicles.

(5) Development of innovative steel sheet
While leveraging the knowledge of the residual γ state control in the Fe-C system in 2014, it was promoted the microstructure control technology for an ideal structure. In addition, less than rare earth element addition amount of 10wt% (it is a 2015 intermedium target), stress-strain curve of the middle and high carbon steel which has tensile strength 1.2GPa with a more than 15% elongation was evaluated in one year ahead of schedule.

(6) Development of thermoplastic CFRP
In the development and the development of structural design and application processing technology of thermoplastic CFRP, as the goals of 2015, the establishment of LFT-D element technology (the project goals) and the physical properties based on it was achieved.

(7) Innovative carbon fiber base technology development
Based on the innovative carbon fiber manufacturing technology developed up to now, we have developed high multifunctional carbon fiber that enables innovative carbon fiber / resin composite with excellent mechanical properties.

(8) Strategic and basic research
As strategic issues research, we carried out surveillance of new structural materials. We also researched and developed a joining technology, individual issues (materials), and also have investigated the application technologies of the transport equipment, such as an automobile (e.g. participation in an international body meeting, the DOE peer review meeting).
Feasibility study on structural material analysis technology (by using neutron radiation) and investigation of structural material adhesion technology have finished in FY 2016, which was advanced to a new public offering.
