Effect of Extrusion Ratio on Fatigue Properties of Hot-Extruded Magnesium Alloys

Abstract:

Article Preview

In the present study, fatigue experiments were conducted using two kinds of extruded magnesium alloys with different extrusion ratios. Effect of the extrusion ratio on fatigue lives and crack propagation behavior was studied in detail. There was no dramatic effect of the extrusion ratio on fatigue life, fatigue limit and crack propagation behavior.
