Answer
The four measures that may be taken to increase the fatigue resistance of a metal alloy are as follows:
1. Polishing the surface to remove stress amplification sites.
2. Reducing the number of internal defects by means of altering processing and fabrication techniques.
3. Modifying the design to eliminate notches and sudden contour changes.
4. Hardening the outer surface of the structure by case hardening or shot peening.
