Comparison of Microstructure and Properties of Nickel-Copper Alloy Prepared by Casting and Laser Powder Bed Fusion Processn

Original language description

Nickel-copper alloys are commonly used in highly corrosive conditions where strength is nrequired. Typical applications are in the marine sector, petrochemical industry, or energy facilities nsuch as chemical tubes, pumps, heat exchangers and superheated steam systems. This paper compares nthe microstructure and mechanical properties of a cast alloy with a 3D printed alloy processed via a nlaser powder bed fusion (LPBF) technique. Small cylindrical specimens were used for tensile tests at nroom temperature (RT) and elevated temperatures up to 750 °C in air. The tensile stress-strain nresponse was determined for both types of materials. At RT, LPBF material has a higher yield strength nand ultimate tensile strength than a cast alloy. At elevated temperatures, the strength of both variants nis comparable. However, the fracture elongation of the LPBF material is significantly lower over the nentire range of investigated temperatures. Fracture surfaces and polished sections parallel to the nspecimen axis were investigated to compare the microstructure and damage mechanisms of the nnickel-coper alloy 400 prepared by conventional casting and via LPBF.
