µ-Kern: Microstructure based calculation method for the technological properties of inorganically bound sand cores.

在环境保护法和全球环保生产目标的推动下，世界各地的轻金属铸造厂越来越多地使用无机粘合砂芯。这些岩心由天然石英砂组成，由硅酸盐粘合剂粘合。它们的工艺性能、机械强度、透气性、导热性和热容量对铸件质量至关重要。到目前为止，砂和粘结剂特性对这些工艺性能的影响仅仅是用启发式方法描述的。该项目的目的是开发和验证一种计算方法，该方法可以根据成分的性质确定无机粘结砂岩心的工艺性质。数值方法是基于材料微观结构的三维模型。

Motivated by environmental protection laws and the global goal of an eco-friendly production, inorganically bonded sand cores are being used more and more often by light metal foundries around the world. These cores consists of natural quartz sand, which is bonded by silicate binders. Their technological properties mechanical strength, permeability, thermal conductivity and heat capacity are critical for the casting quality. The effect of sand and binder characteristics on these technological properties have merely been described by heuristic methods until now. The aim of this project is to develop and validate a computational method, which determines the technological properties of inorganically bonded sand cores based on the constituents' properties. The numerical method is based on a three-dimensional model of the material's microstructure.
