SUMMARY
The forum discussion centers on solving the Hall-Petch equation, specifically the calculations involving the yield strength (σy) of titanium. The participants confirmed that the initial calculations yielded σo = 4.18142 x 10^8 Pa and k = 131354. However, a correction was made regarding the second part of the solution, where the yield strength was initially miscalculated as σy = 7.11858 x 10^-6 Pa, which was later corrected to σy = 7.1 x 10^8 Pa. This highlights the importance of unit consistency in material strength calculations.
