The finite element method is used to analyze the relationship between strength and stress of the particle reinforced iron matrix composites and the shapes, sizes and fraction volume of the particles.
采用有限元方法分析了颗粒增强铁基复合材料强度和应力与颗粒形状、尺寸以及体积分数的关系。

The method requires less computation time and smaller memory than the direct computation of volume integral equations, since the large scale matrix inversion may be avoided.
Compared with traditional austempered process, this new method would obtain much finer structure with nearly same volume fraction of retained austenite in matrix and carbon content of austenite.
