Question details

Question 2

a) Sketch the stress strain curves up to its yield strength for the following materials; i) AISI 1045, ii) Ti-6Al-4V, iii) Al-6092 and iv) Inconel 718. Label the magnitude of yield strain and yield stress.

b) Briefly explain how the C and m value affect production planning in terms of out sourcing, use of external heat source, increasing rate of deformation and purchase of new equipment.

c) Sketch the trend on how thermal softening will affected the plastic flow stress when m=1, m>1 and m<1
