碩士 === 國立中正大學 === 機械工程學系暨研究所 === 102 === In this study, we establish a complete set of analytical to the new ultra-fine aluminum powder metallurgy composite materials.This material is compared to a pure aluminum,with a more excellent strength.by powder and different metallurgy processing,alumina disperses in the microstructure whit different type,and influence the material properties. Acoording to this Metal Matrix Composite(MMC) material,this study base on heterogeneous infinite element method(HIEM),which base on infinite element method(IEM),assembly with finite element method,to provides a convenient method of analysis.and possibly to discuss the interaction effects in each material in the microscopic scale,Compared with finite element method,the execution time in the modeling stage,the number of DOFs,and PC memory storage were significantly reduced by using heterogeneous infinite element method,Second,conduct with Gleeble thermal simulation and static tensile test,the result were discussed,and use those experimental result to predict artificial neural network(ANN),asses the relationship between material properties and powder size.When the neural network validation is complete,the network will be able to use in material properties prediction.
