The tensile properties of an alloy can be exploited if detrimental defects and imperfections of the casting are minimized and the microstructural characteristics are optimized through several strategies that involve die design, process management and metal treatments. This paper presents an analysis and comparison of the salient characteristics of the reference dies proposed in the literature, both in the field of pressure and gravity die-casting. The specimens produced with these reference dies, called separately poured specimens, are effective tools for the evaluation and comparison of the tensile and physical behaviors of Al-Si casting alloys. Some of the findings of the present paper have been recently developed in the frame of the European StaCast project whose results are complemented here with some more recent outcomes and a comprehensive analysis and discussion.
如果通过涉及模具设计、工艺管理和金属处理的多种策略，将铸件的有害缺陷和不完美之处降至最低，并优化微观结构特征，那么合金的拉伸性能就可以得到利用。本文对文献中提出的压力铸造和重力铸造领域的参考模具的显著特征进行了分析和比较。用这些参考模具生产的试样，即单独浇注的试样，是评估和比较铝硅铸造合金拉伸性能和物理性能的有效工具。本文的一些研究结果最近在欧洲StaCast项目的框架内得到了发展，该项目的结果在此得到了一些更新成果以及全面分析和讨论的补充。
