Question

9. List four measures that may be taken to increase the resistance to fatigue of a metal alloy

Answer 1

Fatigue resistance: Fatigue refers to the weakening of a material caused by loads and the resistance to fatigue is referred to as fatigue resistance.

The fatigue resistance is one of the property of the durability of the metal alloy.

Measures to increase fatigue resistance:

• Removing the stress amplification sites by polishing the surface.
• Using fabrication to reduce the number of internal defects.
• Eliminate notches.
• Using carburizing or nitriding to harden the outer surface.
