Question

14. Tor F Barrier coatings, such as paint, on steel protect it from corrosion. 1S. TorF. Processing steel by rolling leads to differences in transverse and longitudinal elongation 16. TorF. Secondary bonds are weaker than primary bonds. 17. TorF Atomic spacing in a solid depends on the temperature of the solid. 18 TorF. The interatomic spacing is determined by the sum of the attractive and repulsive forces 19. TorF. Atomic bonding does not strongly influence strength or mechanical response to stress 20. TorF. Density depends on atomic weight and the arrangements of atoms in a solid 21. TorF An interstitial is the same as a vacancy in an atomic structure 22. TorF A mix of two compounds A and 8 will form a solid solution with a eutectic point 23. T or F. Alloy atoms must have more than a 15% difference in atomic radius compared to the base metal in order to obtain complete miscibility 24. TorF. Plastic deformation can occur easily along a slip plane 25. TorF. Cold working metals decrease tensile strength of the worked metal 26. The hardness of a sample increases with a.
