The Study of Solidification Behavior in Cast Irons Using the Linear Displacement Method

Abstract:

This study aims to assess the solidification shrinkage and expansion during the solidification of cast irons. The solidification shrinkage and expansion in cast irons are due to the formation of austenite and graphite respectively. In this study, the linear displacement method was used to observe the solidification event combined with the cooling curve analysis. It was found that the cooling and displacement curves show good correlations in time of events during solidification. The displacement due to graphite expansion increased with the carbon equivalent. The linear expansion of 0.2 to 1.9 mm was observed for the carbon equivalents ranged from 3.7 to 4.5. On the other hand, the displacement due to the austenite shrinkage was found to decrease with increasing carbon equivalents.
