An uncold-worked brass specimen of average grain size 0.008 mm has a yield strength of 160 mpa (23,500 psi). estimate the yield strength of this alloy after it has been heated to 600°c for 1000 s and has achieved grain size of 0.20 mm, if it is known that the value of ky is 12.0 mpa-mm1/2 (1740 psi-mm1/2).
