Abstract: PURPOSE: A method for simulating molecular dynamics of carbon-nano tube-reinforced metal matrix composites is provided to prepare a simulation foundation for measuring an elastic modulus of a material by suggesting a molecular dynamics simulation method. CONSTITUTION: A computer separately sets base Al(Aluminum) and additive CNT(Carbon NanoTube) and composes a simulation unit cell with the Al and the CNT. The computer optimizes an atomic structure in a composite. The computer stabilizes the volume of a basic model with attribute calculation simulation conditions and determines the atomic structure by minimizing the whole energy. The computer calculates stress by applying power to a simulation cell and calculates an elastic coefficient. [Reference numerals] (AA) Start; (BB) Set a CNT/A1 model; (CC) Optimize a structure; (DD) Prepare a simulation specimen; (EE) Calculate an elastic coefficient; (FF) End

Abstract: PURPOSE: A thin film for coating the surface of a shaping device and a surface processing method are provided to enable a product to be shaped in a desired shape since a freedom of shape increases when a product using a high-strength/high-tension steel sheet, such as a vehicle body is shaped. CONSTITUTION: A method of processing the surface of a shaping device comprises next steps. CrN is sputtered at a mixed gas atmosphere of N, O, and Ar and is excited onto a deposition substrate. Mo is sputtered at the mixed gas atmosphere and MoN, MoOx, and Mo are excited onto the deposition substrate. A thin film of mixed composition, which is represented as CrMoOxN1-x, is formed on the deposition substrate.
