14- With regard to imperfections in solid metals, which of the following information is/are true? I- Motion of dislocations through grain boundaries requires extra energy. Il-Existence of impurity atoms in solid metal (alloying) would increase its electrical conductivity. III- Yield strength of a metal increases as the grain size decreases. A- Only I. B- Only II. C- Only III. D- I and III. E- H and II.

A nodukat or ductile cast-iron is identified by the ASTM with a three part grade designation. And example of the gray designation is a 55 Dash 35 Dash 25 nodular cast iron. This designation has the following meeting. 55 is the tensile strength in KSA, 35 is a yield strength and KSI, and 25 represents 25% elongation. Another jeweler or ductile cast-iron is identified by the a STM with a three part grade designation. And example of the gray designation is a 55 -35 -25 nodular cast iron. This designation has the following meeting. 55 is the tensile strength in KSA, 35 is a yield strength and KSI, and 25 represents 25% elongation percent elongation. True or false

What are valid reasons for adding Yttrium to the zirconia in the Thermal Barrier Coating (TBC) in a turbine blade? Select one or more: a. To increase the weight of the TBC b. To match the thermal conductivity of the TBC to the underlying oxide layer To avoid breakage during change in thermal conditions d. To prevent a change of the crystallographic structure as the temperature changes To match the thermal conductivity of the TBC to the metal substrate C. e.

Circle all correct statements for the Young's or elastic modulus, E: a. Has units of force per unit area. b. Is a measure of the ductility of a metal. c. Can be used to determine transverse strains in uniaxial loading. d. Is a material property. e. Is the slope of the elastic portion of a stress-strain (s-e) tensile curve Circle all of the statements that describe interstitial solid solutions: a. Is an example of a line defect. b. A solute atom replaces a solvent atom in the matrix. c. Would predict formation when adding carbon (C) to iron (Fe). d. Would predict formation when adding chromium (Cr) to iron (Fe). e. Requires the formation of a cation-anion vacancy pair. f. The solute atom has a smaller radius than the solvent atom.

O A cylindrical rod made from an unknown metal is 350mm long and has a diameter of 10mm. The rod is subjected to a tensile load. It experiences only elastic deformation and elongates by less than 1.0mm under an applied load of 19,800N. Could any of the four metals listed in the table below could be the unknown metal? If so which ones and why? Material Modulus of Yield Ultimate Elasticity / GPa Strength / MPа Tensile Strength / MPа Aluminium 70 255 420 alloy Brass 100 345 420 Copper alloy Steel 110 250 290 207 450 550
