Shown below is a ITT diagram for a eutectoid steel with $0\mathrm{.}77$ wt$.\%$C$.$ Small, thin pieces of $0\mathrm{.}25$mm thick hot$-$rolled strips of eutectoid steel are heated to $800\backslash$deg C and then held at $800\backslash$deg C for $1$ hour. The steel is then given the six different heat treatment shown in the isothermal transformation diagram below. Determine the microstructures of the samples after each heat treatment.
