SUMMARY
The discussion centers on the relationship between interlamellar spacing in pearlite and the degree of undercooling during cooling processes. It is established that increased undercooling leads to finer lamellae due to the formation of more nucleation sites, which are critical for the initial precipitation of lamellae. This phenomenon is consistent across various alloy systems where secondary phases differ chemically from the primary alloy solution. The rapid cooling and lower temperatures enhance nucleation, resulting in a more refined microstructure.
