CoursHeroTranscribedText: (iv-12 points) What is/are the resultant phase or phases present when a eutectoid steel is first quenched to the 50% line at Ms >T > Mr at a rate faster than the CCR, and then isothermally held for t>104 sec, followed by rapid reheating to TN>T>Mr, held there for 104 sec and then slowly cooled to room temperature. Sketch the heat treatment process on the TTT diagram provided herein. (v-12 points) What are the major characteristics of eutectoid and martensitic transformations in steel? Briefly compare and contrast them
