Temperature-Dependent Material Property Databases for Nickel-Aluminum Bronze, HY-80 and HY-100 Steels

To address residual stress and distortion issues in castings, weldments and additive manufacturing of marine structures, Integrated Computational Materials Engineering (ICME)-based techniques enable process engineers to elucidate thermal effects through computational simulation. For this, ICME tools require reliable temperature-dependent material data to achieve accurate computational results for distortion and residual stress during fabrication. Thermo-physical properties of importance to the fidelity of such software tools include liquid density, surface tension, and dynamic viscosity. High yield strength steel alloys and nickel-aluminum bronze (NAB) are commonly used for U.S. Navy applications. However, limited information is available regarding the high temperature, liquid phase properties needed for accurate computational results. The following data descriptor report documents the thermo-physical properties of material taken from HY-80 and HY-100 steel plates and an NAB additive deposition. These results will enhance ICME efforts through the integration with commercial software packages. The raw data, in machine-readable form, will be available at the University of Michigan’s Materials Commons data repository at the University of Michigan’s Materials Commons data repository: https://materialscommons.org/ .
