<p>The effect of fourth pass cold reduction and final anneal
temperature were investigated for aluminum alloy 3104. The
material was received at 0.019" (82% reduction) and further
reduced to: 84%, 86%, 88%, and 89%. The material was then
heated for 2 hours between 85°C and 160°C.</p> <p>
Samples were uniaxially tensile tested at 0.0167 per
second for yield strength, ultimate strength, and total
percent elongation. Samples showed an increase in ductility
with increasing temperature. This is believed to be the
result of recovery. Prior processing limited the possibility
that age hardening effects would occur. No age hardening was
found. TEM micrographs showed no evidence for the presence of
GP zones or the S' Al<sub>2</sub>CuMg metastable phase.</p> / Master of Science
