Solved Below Is A Ttt Diagram For Hypereutectoid Steel 1 Time temperature transformation (ttt ) diagram. t (time) t (temperature) t (transformation) diagram is a plot of temperature versus the logarithm of time for a steel alloy of definite composition. it is used to determine when transformations begin and end for an isothermal (constant temperature) heat treatment of a previously austenitized alloy. Salt bath i (fig. 1) is maintained at austenetising temperature (780 ̊c for eutectoid steel). salt bath ii (fig. 2) is maintained at specified temperature at which transformation is to be determined (below ae1), typically 700 250°c for eutectoid steel. bath iii which is a cold water bath is maintained at room temperature.

The construction of the ttt diagram involves several steps to accurately represent the transformation kinetics of the steel. step 1: the first step in constructing the ttt diagram is to obtain the experimental data through cooling curve experiments. in these experiments, a small sample of eutectoid steel is heated to a high temperature and then.
