Lab 1 - Expected Results<br />
• Hardness: before recrystallization, the hardness should<br />
increase with increasing strain (hint - relate this to what you<br />
know about stress-strain behavior in metals).<br />
• After recrystallization, the grain size will increase with<br />
increasing temperature, but decrease with increasing prior<br />
strain.<br />
• Also after recrystallization, the hardness will increase with<br />
decreasing grain size (Hall-Petch effect) in the recrystallized<br />
areas.<br />
• Note: a critical part of the Lab is to obtain high quality images<br />
of the grain structure so that you can measure grain size. The<br />
metallography involved requires skill and effort. Also,<br />
computer-based submissions are required (Word, or LaTex).<br />
