7. Influence of temperature<br />
on mechanical properties<br />
Alum<strong>in</strong>ium alloys change their<br />
mechanical and corrosion resistance<br />
properties when subjected<br />
to temperatures other than<br />
ambient temperature. Tables V.6<br />
& V.7 show the <strong>in</strong>terrelationship<br />
between service temperature<br />
and mechanical properties. In<br />
Figure V.1 this is shown for one<br />
alloy graphically.<br />
