You have been given a task to make three steel swords (A, B, C) with sharp edges. Three pieces of
rectangular martensitic steel bars (40 mm x 100 mm x 1000 mm) with a composition of Fe-0.76
wt.%C (eutectoid composition) are provided as starting materials. In the workshop, a cutting
machine, one CNC machine, a large furnace with a maximum working temperature of 1200 C, and
a cold-water bath are available for machining and processing. The required values of final Vickers
microhardness (HV) of A, B, C are 350-400, 550-700 and 900-950, respectively. Design and justify
the proper processes from which you can make these steel swords with the required hardness. (Hint:
Fe-C phase diagram and TTT diagram can be used for your design and justification) State any
assumptions and claims such as cooling and heating rates used in the process or dimensions of the
item.
