Question $1$ From the tensile stress$-$strain behavior for the given material $($inconel$),$

determine the following:

$($a$)$ Stress$-$strain curve, find the modulus of elasticity

$($b$)$ Yield strength, $($use the offset method if not prominent$)$

$($c$)$ The maximum load that can be sustained by a cylindrical specimen having an original

diameter of $12\mathrm{.}8$ mm

$($d$)$ The change in length and strain, of a specimen originally $250$ mm long that is subjected

to a tensile stress of $345$ MPa

$($e$)$ Write the Poisson's ratio and calculate the strain in z$-$direction

Fill this table at the end of calculation:

Question $2$ What is meant by the following?

$($a$)$ Phase equilibria

$($b$)$ Solubility limit

$($c$)$ Phase diagram

$($d$)$ Eutectic systems
