a Using the isothermal transformation diagram for an ison-Carbon alloy of eatectoid composithan, specify the nature of finel mico constituents Present and approx. 14 sata (in terms of microconstituents Present and approx. 7 of each of a small specimen that has been Subjected to the following time-stamp treatments. . In such case assume that the specimen begins at 760 ( 1400 ft) and that it has been held at this temp. long enough to have achieved Complete and homogeneous @ Cool rapidly to tose, hold for 10,000s, then quench to room temp. 6 Cool rapidly to 400e hold for 2sec, then quench to room temp. the two microstructure ostained by heat treatment (a) and heat treatment a (6) which will have highest tensile Strength.?
