Answer 1

Explanation:

is the question completed

Answer 2

Answer:

our measures that may be taken to increase the fatigue resistance of a metal alloy are as follows: (1) Polish the surface to remove stress amplification sites. (2) Reduce the number of internal defects (pores, etc.) by means of altering processing and fabrication techniques. (3) Modify the design to eliminate notches and sudden contour changes. (4) Harden the outer surface of the structure by case hardening (carburizing, nitriding) or shot peening.
