Hi all,
i found your group through google, i am a mechanical engineering
student at RIT and i am having problems with an assignment i was given
so i was wondering if you all would be able to provide some input as i
am at a lack of where to go with this.
Design a process to produce a 0.5-cm-diameter steel shaft having
excellent toughness, yet excellent wear and fatigue resistance. The
surface hardness should be at least HRC 60, and the hardness 0.01 cm
below the surface should be approximately HRC 50. Describe the
process, including details of heat-treating atmospher, temperatures,
times, and composition of the steel
any help with this would be greatly appreciated
