According to Reference [1], alloys of nickel (Ni) and tungsten (W) are can form substitutional solid solutions up to approximately 11 at% W. Consider two different alloy compositions: Ni-5W (5 at% W) and Ni-10.5W (10.5 at% W). A. Which composition should be more ductile? B. Which composition should be stronger? C. Using the oy ~ C¹/2 relationship from the lecture slides, how many times larger should the yield strength be for Ni-10.5W compared to Ni-5W? D. Where should the tungsten atoms sit relative to the dislocation on or opposite the side with the extra half-plane? You will need information from Appendixes of the textbook.

Question
According to Reference [1], alloys of nickel (Ni) and tungsten (W) are can form substitutional solid solutions
up to approximately 11 at% W. Consider two different alloy compositions: Ni-5W (5 at% W) and Ni-10.5W
(10.5 at% W).
A. Which composition should be more ductile?
B. Which composition should be stronger?
C. Using the oy~ C¹/2 relationship from the lecture slides, how many times larger should the yield
strength be for Ni-10.5W compared to Ni-5W?
D. Where should the tungsten atoms sit relative to the dislocation on or opposite the side with the extra
half-plane? You will need information from Appendixes of the textbook.
