Problems solved by technology

The lamellar spacing of the Al-Si eutectic structure is a major factor directly related to the mechanical properties of casting products. In the past, the eutectic inter-lamellar spacing of Al-Si alloys was mostly measured by experimental methods. The cost of layer spacing is high, the experiment cycle is long, and the experimental results are significantly affected by the experimental conditions

Abstract

The invention relates to a method for predicting space between aluminium-silicon alloy eutectic structure lamellas; the method is characterized in that an experimental period can be greatly shortened by using a numerical simulation method to predict the space between aluminium-silicon alloy eutectic lamellas; the cost is low, and the prediction result is not limited by the experimental conditions; and the influences of a certain single factor to the space between the aluminium-silicon alloy eutectic structure lamellas can be inspected. The shortages that the cost of the existing experimental method for measuring the space between aluminium-silicon alloy eutectic structure lamellas is relatively high, the experimental period is long and the experiment results are influenced obviously by the experimental conditions are overcome; the computation is fast; the error is small; and the quantitative prediction to the space between eutectic lamellas can be realized.

Description

1. Technical field: [0001] The invention belongs to the technical field of metallurgy, and mainly relates to a method for predicting the lamellar spacing of eutectic structures, in particular to the prediction method for the lamellar spacing of eutectic structures of aluminum-silicon alloys. 2. Background technology: [0002] Aluminum-silicon alloy is one of the most widely used aluminum alloys, and it is widely used in automobiles, electric power, aviation and other fields. Casting is a main method of aluminum silicon alloy forming. However, in the casting process, the Al-Si eutectic structure is a typical solidification structure. The lamellar spacing of the Al-Si eutectic structure is a major factor directly related to the mechanical properties of casting products. In the past, the eutectic inter-lamellar spacing of Al-Si alloys was mostly measured by experimental methods. The cost of layer spacing is high, the experiment cycle is long, and the experimental results are ...
