Cold Working of metals

1- Describe the experimental technique in your own words.
2- complete table 1: Rolling mill data below.
3- plot graphs of (deformation is plotted on the horizontal,x.axis):
a- hardness versus deformation(%).
b- temperature increase versus deformation(%).
c- power versus deformation(%).
d- load versus deformation(%).
4- Critically discuss the results, plotted in the above graphs in relation to deformation of the strip and comment on the hardness of the material that has been annealed(part 2).
5- compare and contrast the advantages and disadvantages of hot and cold working of metals Give typical applications of hot and cold rolled materials and products
