During the tensile test of a metal, it was observed that when the true stress is $29,500$

$l\frac{b}{i}{n}^2,$ the true strain is $0\mathrm{.}32.$ Then, at a true stress of $32,000l\frac{b}{i}{n}^2,$ true strain is $0\mathrm{.}52.$

Determine the strength coefficient and strain$-$hardening exponent in the flow curve

equation. Based on the obtained strength coefficient and strain$-$hardening exponent,

what is the likely material for this specimen?
