a) Assume that a material has a yield strength of 520 MPa when the grain size is 50 microns and 500 MPa when the grain size is 60 microns. Use the graph below to determine what anneal temperature is required to reduce the yield strength to 450 MPa. Grain Size (um) 140 120 100 BO 50 40 20 0 D 100 Grain Growth 200 300 400 Anneal Temperature (C) 500 600 b) If the hardness of this unannealed material is HB 76, what is the approximate hardness after annealing at 500°C? How could you bring the hardness back to HB 76 after annealing? a) Assume that a material has a yield strength of 520 MPa when the grain size is 50 microns and 500 MPa when the grain size is 60 microns.
