Question: engineering material question please help question a and b...

Question details

a) Plot (koordinat log) kadar rayapan lawan tegasan untuk tiga suhu tersebut. Tunjukkan pada plot anda kawasan tegasan yang bersamaan dengan rayapan resapan dan rayapan power-law. Plot (logarithmic coordinate) creep rate vs. stress for the three temperatures. Identify on your plot the stress regions that correspond to diffusional creep and those that correspond to power-law creep. (10 markah/marks) b) Adakah kawasan rayapan resapan tersebut bersamaan dengan rayapan Nabarro-Herring ataupun rayapan Coble? (Panduan: Tenaga pengaktifan untuk rayapan NH dan power-law adalah sama, dan lebih besar daripada tenaga pengaktifan rayapan Coble.) Does the diffusional creep region correspond to Nabarro-Herring creep or to Coble creep? (Hint: Recall that the activation energies for NH creep and power law creep are the same, and greater than that for Coble creep.) (5 markah/marks)
