Titanium alloys provide good strength with low density and are used in many applications where weight is an important design factor. Pure titanium $($commercially pure$)$ and titanium with $6\%$ aluminun and $4\%$ vanadium are the most commonly used alloys. The attached data sheets $($pdf and Excel$)$ give tensile test data for both of these.

Details & In

Assessme $2/19/24,1$

For each alloy.

$1.$ Convert the load$/$displacement data to stress$/$strain and plot.

$2.$ Determine the elastic modulus, E$,$ in GPa.

Attempts Unlimited

$3.$ Determine the $0\mathrm{.}2\%$ yield strength, $00\mathrm{.}29\%$ in MPa.

$4.$ Determine work$-$of$-$fracture in kJ$/$m$^2.($Work $=$ load x displacement, i$.$e$.$ the area under the load$-$displacement curve. Divide by cross$-$section area to get per m$^2.)$

Grading

$5.$ What strengthening mechanism is used for Ti$-6$Al$-4$V$?$
