Application

Erbium has limited commercial use, but it is used as an alloy metal for vanadium to makeit easier to work and to form spring steel. The oxide of erbium is pink, which is used to colorglass and to make lasers that will operate at normal room temperatures. It has limited use ascontrol rods in nuclear fission reactors.

Erbium Powder Used to Improve Defects in Selective Laser Melting of 7075 Aluminum Alloy

Zhang, Xuhui, et al. Virtual and Physical Prototyping, 2022, 17(2), 406-418.

7××× series aluminum alloy is a high-performance, lightweight alloy with a wide range of applications. However, 7075 aluminum alloy is prone to cracks during the selective laser melted (SLMed) manufacturing process. Erbium (Er) can modify aluminum alloys to prevent cracks during the manufacturing process.
Effect of adding Er on aluminum alloy
Samples were fabricated using 7075 aluminum alloy powder unmixed and mixed with 2 wt% Er element powder.
· After adding Er, the crack density decreases, but the porosity increases.
· Er additives exist in the form of unmelted particles and submicron Al3Er.
· The consistency between the aluminum matrix and Al3Er is conducive to grain refinement, thereby reducing cracks.
· Due to insufficient energy density, Er with a high melting point is not completely melted, resulting in higher porosity.
