When the temperature of aluminium is increased, the metal expands and this is called thermal expansion. One example of thermal extension is that if, for example, the temperature of a piece of aluminium alloy 6063 is -20 C and its length is 2700 mm long, and it is heated to a temperature of 30 C, it will subsequently be 2703 mm long due to thermal expansion.
Dec 01, 2019 Thermal expansion can be problematic in many areas of engineering, not least during the PBF process itself where higher silicon content in aluminium alloy powders can help lower thermal expansion and prevent crack formation during the rapid melting and solidification process. In metallic solids, the crystalline structure of atoms is relatively compact at 0 K, but as temperature increases the ...
