Estimation Method of Metal Deformation by Analytical and Model Simulations

研究了锻造过程中材料微观组织的估算方法。通过有限元和模型试验，比较了微观组织与锻造条件之间的关系。建立了显微组织及温度、应变、应变率等条件数据库。采用不锈钢和塑料作为模型试验的试件。该估算方法与SUS304的实际微观结构变化吻合较好。锻造过程的模拟2。塑料实验模型3。在SUS304不锈钢锻造中的应用通过与不锈钢实验的比较，证实了该估算方法的有效性。有足够数据库的有限元模拟被认为是锻造工艺设计的有力工具。

Estimation method of micro-structures of materials worked during forging processes is studied. FEM and model experiments are used in comparison with the relationship between micro-structure and forging conditions. Data-base for micro-structure and other conditions such as temperature, strain and strain rate is constructed. Stainless steel and plasticine are used as samples of model experiment. This estimation method confirmed good agreement with actual micro-structure change of SUS304.Sub-themes are following.1. Simulations of Forging Process2. Model Experimental by Plasticine3. Application to Forging of SUS304 Stainless SteelThis estimation method is confirmed by the comparison of stainless steel experiments. FEM simulation with adequate data-base is probed to be a powerful tool for the design of forging operation.
