“…In addition to the three ingots described above, a commercial hot rolled bar was purchased from Haynes International. The solubilization treatment conducted on the specimens produced from the three ingots and the rolled bar, as well as on the forged material, that will be discussed below, is the standard treatment [17,20]. The solubilization treatment was carried out at 1100 °C for 1 hour and the subsequent cooling was carried out in air.…”

The satellite LARES 2 is designed to test dragging of inertial frames, or frame-dragging, predicted by Einstein’s theory of General Relativity, with accuracy of a few parts in a thousand. For this purpose, besides the typical requirements for a space construction, a high density alloy must be used. In this paper are reported the studies performed on a nickel alloy, the Haynes 242, that is considered a possible candidate for manufacturing all the metallic parts of LARES 2 and other passive geodetic satellites. Haynes 242 density and mechanical properties are compliant with the requirements of the mission. Three different casting with the nominal composition of the alloy have been prepared and tested along with a commercial bar of Haynes 242. The results of tensile and hardness tests on several specimens with different aging time are reported, along with the relevant metallographic analysis. Furthermore, a test on the machinability, performed on a screw, which is the most demanding item from the manufacturing point of view, is reported.

“…In particular, it is important to study which technology can be usefully applied to the different candidate alloys. Among the alloys having mechanical properties close to the requirements the HAYNES® 242 ™ alloy is one of the most interesting [17][18][19][20][21][22]. This alloy was originally developed for applications in gas turbines.…”
