摘要：

This paper reports an analysis of the accuracy and sensitivity of ultimate tensile strength and strain to failure to changes in microstructure constituents in Al-Si alloys ranging from 7 to 18%Si. The influence of amount of constituents, namely dendrites, eutectic, silicon particles and intermetallics as well as their geometrical features, namely secondary dendrite arm spacing, silicon eutectic thickness and intermetallics thickness on both ultimate tensile strength and strain to failure is evaluated. This study provides information that will be useful in the establishment of robust correlations between mechanical properties and metallurgical features, since they are highly dependent on their sensitivity and accuracy.
