Material Research Laboratory
The Materials Research Laboratory bases its research on four technical fields: refining and solidification, materials design, mechanical working, and surface control. For the materials business, it is working to develop new high-performance products based on material and surface design and control, as well as optimize manufacturing processes. For machinery-related businesses, it focuses on creating differentiated products utilizing its expertise in materials. It also strives to develop new businesses based on high value-added products. Refining & Solidification: High-temperature metallurgical reaction and control; inclusion structure and morphology control; solidification analysis and solidification structure control; high-temperature in-situ monitoring; special melting technology Materials Design: Structure/property prediction; nanostructure analysis; microstructure control and materials design; material structure and transformation; powder metallurgy Mechanical Working: Rolling, forging and extrusion; cutting and polishing; forming process analysis Surface Design: Corrosion resistant and environment resistant material design; face/interface design and process control; tribological materials design; electronic, thin film material, and nanostructure design
High strength valve spring steel
The fatigue strength of valve spring steel and bearing steel is improved by minimizing the amount and reducing the size of inclusions.
Excellent formable high strength steel sheet -automobile seat-
Ultra high strength steel sheet with excellent formability has been developed by means of microstructure control in order to both reduce the weight of the automobile and to improve its crashworthiness.
Numerical simulation of R-R forging
Numerical simulation of sheet metal forming
The process condition is optimized, considering the estimated results of material profiles and properties on the processes, such as rolling and forging, by applying numerical simulation and experiments.
Nano-multilayer wear resistant coatings
Advantageous performance in Hardness, Oxidation Resistance, and Wear Resistance has been achieved by nano-multilayer thin film, such as TiAlN. The possible and expected application is for tribological components such as automotive parts and cutting tools.
