3. An uncold-worked brass specimen of average grain size 0.01 mm has a yield strength of 150 MPa (21,750 psi). Estimate the yield strength of this alloy after it has been heated to 500°C for 1000 s, if it is known that the value of σo is 25 MPa. (Note that the axis has logarithmic scale).

9. Consider a metal rod, whose grain size can be adjusted by different processing techniques. The graph below shows how the yield stress changes with grain size d; the x-axis is logarithmic. The curve reaches a limiting value of 60 MPa as indicated by the horizontal dashed line on the y-axis, for very large grain sizes. Also, you are given the information that at d = 25 microns (vertical dashed line), the yield stress is 100 MPa. Using this information, what will be the yield stress at d = 5 microns? Select the closest numerical value. Use the Hall-Petch relation in working out your answer.

Question 1 You are working on a design team at a small orthopaedic firm. You have been asked to select a cobalt- chrome-molybdenum (CoCr) material that will not experience plastic deformation under a specific mechanical test, as follows... A tensile stress is applied along the long axis of a solid cylindrical rod that has a diameter of 10 mm. An applied load of some magnitude F produces a 7x10-³ mm change in diameter (see figure below, original shape is blue, elongated shape is unshaded). Q1A-B: Calculate the transverse strain in the x-direction (Ex) associated with the reduction in diameter. Calculate the axial strain in the z-direction (₂) associated with the length increase.
(b) The yield stress for a metal changes from 450 Nmm-2to 610 Nmm-2 when the average grain diameter decrease from 0.043 mm to 0.022 mm. Determine the yield stressfor the same metal with an average grain diameter of 0.030 mm.
