Question:

Is it possible to produce iron-carbon alloys of eutectoid composition that, using isothermal heat treatments, have the following tensile strength-ductility (%RA) combinations? If so, for each combination describe the heat treatment required to achieve these properties. Or, if this is not possible, explain why.
(a) 1800 MPa and 30%RA
(b) 1700 MPa and 45%RA
(c) 1400 MPa and 50%RA
