本研究的主要目的是对半固态钢的流变性能进行分析。结果用于开发表观粘度的数学模型。流变特性的知识对于工艺过程的数值模拟至关重要。半固态成形又称触变成形工艺，是一种创新的金属合金加工方法，与传统的金属成形和铸造工艺相比具有许多优点。目前，人们以该方法在钢材加工中的实际应用为目标进行研究[1,21]。这项特别研究最重要的成就是应用了专为在极高温度下执行的材料测试而设计的粘度计，例如测量液态或半液态钢的粘度。本文介绍了 100Cr6 (RN LH15) 工具钢的流变分析结果。它是使用带有固定外杯的旋转粘度计进行的。
The main objective of this study was to conduct an analysis of the rheological properties of steel in a semi-solid state. The results were used for the development of mathematical models of the apparent viscosity.Knowledge of the rheological properties is crucial for the numerical modeling of technological processes. Shaping in the semi-solid state, also known as thixoforming processes, is an innovative method of processing metal alloys and has a great many advantages in comparison with classical metal forming and foundry processes.Nowadays, research is conducted with the practical application of this method in steel processing [1,21 as its goal. The most significant achievement of this particular study is the application of a viscometer which was specially designed for material tests executed at extremely high temperatures, such as the measurement of liquid or semi-liquid steel viscosity. This paper presents the results of a rheological analysis of 100Cr6 (RN LH15) tool steel. It was performed using a rotational viscometer with a stationary external cup.
