The amount of test cycles required to find out the fatigue stress of hard aluminium alloys is ____________ Correct Answer 500,000,000

A huge number of test cycles are required to determine the fatigue strength of a material. The number of cycles required for aluminium alloys is 500,000,000. It is the same for magnesium alloys as well.
