Mostly fatigue if you have reversed (tensile/compressive) stresses.
Stress
Fatigue crackling occurs in materials when repeated cyclic loading, such as stress or strain, is applied. This leads to the growth of micro-cracks in the material that eventually coalesce and result in larger cracks. Proper stress levels and a sufficient number of load cycles are required for fatigue crackling to occur.
