AB Acid mine drainage severely affects metallic materials due to the high acidity and oxidising capacity of theselixiviates. A study was carried out to evaluate the time evolution of the mechanical properties of AISI 1020carbon steel and AW6060 aluminium in contact with acid mine drainage. Weight loss, fatigue and tensilestrength were evaluated in two different scenarios, one involving erosion corrosion (dynamic scenario) and theother involving chemical corrosion only (static scenario). Over 80 days of exposure in a static scenario, weightloss is almost 2% for aluminium and 0.5% for steel, fatigue strength is reduced by 28% for steel and ultimatetensile strength is reduced by almost 5% for aluminium and by 2.5% for steel. In a dynamic scenario, the weightloss after 4 days of exposure is 30–35% for both materials, the fatigue strength is reduced by almost 50% forsteel, the ultimate tensile strength is reduced by 33% for aluminium and by almost 5% for steel. Acid drainagecauses an increase in brittleness and a decrease in stiffness of these materials, much more rapidly in a dynamicenvironment favoured by the effects of erosion corrosion.
