摘要： PROBLEM TO BE SOLVED: To provide a more accurate and rapid behavior analyzing and evaluating method in relation to a process for forming an organic film on the surface of a metal before the synthesis of an organic film compound and a film forming experiment.
SOLUTION: The potential energies in an atomic or molecular unit of the surface of the metal to be analyzed and the organic film on the surface of the metal are respectively calculated on the basis of a molecular dynamic method by a computer to culculate the most stable structures being the minimum energy values thereof. This calculation is performed using a monomer model as a unit in relation to the organic film and performed in relation to the surface of the metal by constructing the periodic boundary model of a crystal state. Next, the total energy value (=the potential energy value of the periodic boundary model of the surface of the metal-the potential energy value of the monomer model of the organic film) of the most stable structure model wherein the organic film and the periodic boundary model are combined is repeatedly calculated on the basis of molecular kinetics so as to be converged to a definite value to simulate the most stable structure model by the computer. When the total energy value is converged to the definite value, the organic film on the surface of the metal is determined to be stable and the bonded state of the organic film at this time of the behavior reaching the bonded state is analyzed.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a magnesium alloy having stable fine crystal grain structure and excellent formability by solving such problem as coarsening of crystal grains, obstruction to formability and increase of energy consumption and to provide a magnesium alloy member.
SOLUTION: After applying a solution-treatment to the magnesium alloy, in a first forging process, a pre-strain of not less than at least 0.4 is given in a temperature range of 250-400°C and thereafter, an ageing treatment is applied and successively, a secondary forging is performed at a necessary temperature of not higher than the forging temperature. In this way, the fine grains of magnesium compound after ageing-treatment are precipitated and the coarsening of the crystal grains is prevented during the heating process in the secondary forging process. Further, the formed product having about ≤10 μm average crystal grain diameter and the stable fine crystal grain structure of ≤5 μm average crystal grain diameter under a suitable condition with a fining action by forging, and the material excellent in formability for the following working process, can be obtained.
