Identify the microstructure resulting from each of the following heat treatments applied to a 1080 Carbon Steel. Be sure to indicate approximate percentages of all phases present. Each treatment begins with Austenizing at B00 C before beginning the cooling operation (RT= room temperature), Microstructures must be described in terms of Bainite (upper, lower), Pearlite (coarse, medium, fine), Martensite (tempered if applies), spheroidite.
