Question

Ceramic High-alloy steel High C steel steel (HT) (HT) Low C 250 Temperature, °C 0 500

Knowing that all of the above materials except the ceramic are amenable to rolling operations/processes, plot the average flow stress vs. temperature for those materials at 1) Room temperature, 2) 100 oC 3) 200 oC

(Your plots can be rough, and don't have to be perfectly exact!)

    Q-1. You are testing a circular beam of two metals, 1045 steel and 2014-T6 aluminum, in a rotating-cantilever beam fatigue test. If you need to choose one of these metals so that you can essentially design a part made of that metal, and subject the part to a repetitive stress-amplitude without ever failing due to fatigue, which one would you choose. (See the attached figure) Q-2. What is the fatigue strength for the 1045 steel alloy, if you expect to...
