Calculate The Weight Percent Of Proeutectoid Cementite

Observing that the habit plane of bainite approached that of widmansttten ferrite at high temperatures and that of proeutectoid cementite at low, greninger and troiano proposed that bainite grew from the beginning as an aggregate of ferrite and cementite, with competition between the two controlling the habit plane.
