2. (10 pts) A non-cold-worked brass specimen of average grain size 0.010 mm has a yield strength of 180 MPa. Calculate the yield strength of this alloy after it has been heated to 600°C for 12.5 minutes with the average grain size changed to 0.040 mm. It is known that the value of ky = 12.0 MPa-mm'2.
