WebSep 22, 2024 · Metal fatigue occurs when metal becomes weakened through time. Metal products and objects will sustain some sort of stress in their life. If they begin to falter under repeated stresses, they are suffering from metal fatigue. There are three stages of metal fatigue. Stage one occurs after an object has gone through a succession of load cycles. WebThe other half is called reduction. When exposed to oxygen, most metals exchange electrons with the oxygen – oxygen gains an electron, and the metal loses an electron. This exchange leads to the formation of oxidation products, such as rust in iron and the patina in copper. The patina is the green tarnish that forms on copper over time. life cycle argentina
