positive and negative aspects of their operation. (5 marks) b) Consider the grain size strengthening effect in Brass C26000 where oo = 65 MPa and k =0.498 MPa m^0.5 what yield strength will the compound have with a mean grain diameter of 15 µm? (3 marks) c) What will the yield strength be if the manufacturing process is changed so that the mean grain diameter of the compound produced is now 70 µm? (2 marks)
