Read the full statement carefully and answer with the option combination that best completes the entire statement. a pearlite structure is produced when austenite is allowed to transform into pearlite at a temperature that is relatively the eutectoid temperature, and such a structure will be relatively soft and ductile when compared to other a fully pearlitic structural possibilities. hint: there is one key aspect of the pearlite structure that is influenced by the transformation temperature (presuming our temperature of transformation is one that does, in fact, produce pearlite).
