Question #104343
6.Thin pieces of 0.3mm-thick hot-rolled strips of 1080 steel are heat-treated in the following ways:(a) Heat for 1 h at 860°C; water-quench. (b) Heat for 1 h al 860°C; water-quench; reheat for I h at 350°C. What is the name of this heat treatment? (c) Heat for 1 h at 860°C; quench in molten salt bath at 700°C and hold for 2 h; water quench. d) Heat for 1 h at 860°C; quench in molten salt bath at 260°C and hold for 1 min; air-cool. What is the name of this heat treatment? (e) Heat for 1 h at 860°C; quench in molten salt bath at 350°C: hold for 1 h: air-cool. What is the name of this heat treatment? (f) Heat for 1 h at 860oC; water-quench; reheat for 1 h at 700°C. Use the IT diagram below and other knowledge to determine the microstructure of the steel samples after each heat treatment. Note that there are other questions stated between (a) and (f), where relevant, and must be answered as well.
