(a) What percentage of carbon produces the strongest plain carbon steel?
The Attempt at a Solution
I've been posed with the above question and it has lead to some confusion. What is meant by 'strongest'. The question seems to leave open to interpretation what the reader considers to be 'strong' traits of a material. I assume it refers to hardest ? or does it mean the most useable plain carbon steel for mechanical work, so, something with a grain structure near the Eutectoid point on the iron-carbon phase diagram.
Any assistance is appreciated.
