The Micro Mechanism Of The Laser-remelting And Analyzed By Thermodynamic

At first, the recent developments of the laser-remelting technologies are introduced, and the macroscopic characters of the technology are analyzecf briefly. Then the main work in this thesis are researched as follows: 1 )The thesis approached the thermal conduct equation? M.Chester Equations, which have closely relations with the characters of the laser-remelting, and further analyzed the equations in microscopic by phonon theory and the traveling wave solutions of Chester Eq.s wave solved by means of solid quantum theory. 2)The thermal conduct coefficient, i.e. the main parameter of the thermal conduct equation, is analyzed theoretically. 3)The micro mechanism and the thermodynamic characters of the laser-remelting, that is, the microscopic particle diffusion, thermodynamic motion of the boundary surface and free energy of the laser-remelting etc., are analysed by means of quantum mechanics, quantum statistic mechanic and thermodynamics. And then the results of some related experiments are intruduced.
