A material is strained past the yield point, what happens after the stress is removed Grain growth Thermal conduction Fracture Spring back Question 5 (1 point) As the ASTM number increases in a material the average grain diameter decreases the average grain diameter increases the average grain diameter stays the same The logarithm goes to zero Question 6 (1 point) As the number of grains increases The yield strength increases The material becomes more brittle Both A and B None of the above Why are phase diagrams important? They reveal that not all materials have a beta phase They look cool and are complicated They tell us about the pressure and density needed to process the material in the appropriate phase They tell us about the composition and structure which influences the material properties Question 10 (1 point) If a Cu and Ni alloy is cooled from its melting temperature to a solid how does the composition of the solid alloy change as it cools The Ni content increases The Ni content decreases The Ni content stays the same It never turns into a solid Which of the following best best describes the relationship between processing, structure, and material properties independant interdependant E=mc Disfunctional Question 2 (1 point) Long range order best describes which of the following Single crystalline Polycrystalline Amorphous Heterogeneous
