This article develops a novel method for measuring the elastic modulus of hardened silicate binders for foundry cores. We measured hardened silicate binder within the original dimensions of the binder bridges with a nanoindenter. The influence of varying hardening times and temperatures on the elastic modulus was studied. This work aims at modelling and simulating the microstructure of sand core materials. In order to develop a computational model, which determines the mechanical properties of inorganically bound sand, one needs to measure these properties for the hardened inorganic binder itself.

一种测量铸造硅酸盐粘结剂弹性模量的新方法

本文开发了一种用于测量铸造型芯硬化硅酸盐粘合剂的弹性模量的新方法。我们用纳米压头在粘合剂桥的原始尺寸内测量了硬化的硅酸盐粘合剂。研究了硬化时间和温度变化对弹性模量的影响。这项工作旨在对砂芯材料的微观结构进行建模和模拟。为了开发一种确定无机粘结砂的机械性能的计算模型,需要测量硬化无机粘结剂本身的这些性能。
