What happens to the fatigue strength of alloys if altered surfaces are

1.	What happens to the fatigue strength of alloys if altered surfaces are produced in Electro discharge machining?(a) Increases(b) Reduces(c) Enhances(d) ImprovesI have been asked this question during a job interview.I need to ask this question from EDM-Heat Affected Zone (HAZ) topic in division Thermal Processes of Advanced Machining
Answer» The correct option is (B) Reduces The best I can explain: The altered surface layers that are PRODUCED in Electro discharge MACHINING, significantly reduces the fatigue STRENGTH of ALLOYS.
