Grain refinement can strengthen the mechanical properties of materials according to the classical HallPetch relationship but does not always result in better corrosion resistance. During the past few decades, various techniques have been dedicated to refining grain, along with relevant studies on corrosion behavior, including general corrosion, pitting corrosion, and stress corrosion cracking ...

Galvanic corrosion [2] can occur when dissimilar metals are in contact with each other and an electrolyte. For aluminium, a reactive metal in the galvanic series, this is the most common cause of corrosion. When aluminium comes into contact with a more cathodic material it acts as a sacial anode and becomes susceptible to corrosion.

2. Use lemon or lime juice. Lemon or lime juice works particularly well for rust stains on clothing, but it can also be effective on metal if left to work for long enough time. Sprinkle salt over the rusted area, let soak with lemon or lime juice, and then scrape away with a crumpledup aluminum ball.

Copper/Brass/Bronze. Copper, brass and bronze are also corrosionresistant metals. Brass is a copper alloy containing a large amount of zinc. Bronze is a copper alloy that includes a large amount of tin and smaller amounts of other alloying elements. Similar to aluminum, copper forms a protective oxide layer when exposed to oxygen.

The type of change is very dependent on the metal being overheated. A hardened steel that is subjected to overheating may have a serious loss of hardness and strength. This is because overheating changes the microstructure of steel. Overheating can cause changes to the mechanical properties of other metals as well.
