The flow stress (σ) of an alloy varies with strain rate $$\left( \in \right)$$ as σ = 100 $${\left( \in \right)^{0.1}}$$ MPa. When the alloy is hot extruded from 10cm diameter to 5 cm diameter at a speed of 2 cm/s, the flow stress is
A metal powder with an apparent density of 2.5 g/cm3 was compacted in a cylindrical die to a green density of 5.5 g/cm3, If the height of the green sample was 12 mm, then the fill height of powder (in mm) would have been
The strain hardening behaviour of an annealed rod during cold rolling is given by σ = 700 $${\left( \in \right)^{0.2}}$$ MPa. where σ is the flow stress at strain $$ \in $$.
Flow stress after 50% reduction in area of the annealed rod on cold rolling is approximately
