Question
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.
