Haynes International | Date: 2017-01-11

In a method for making a wrought nickel-chromium-molybdenum alloy having homogeneous, two-phase microstructures the alloy in ingot form is subjected to a homogenization treatment at a temperature between 1107C (2025F) and 1149C (2100F), and then hot worked at start temperature between 1107C (2025F) and 1149C (2100F). The alloy preferably contains 18.47 to 20.78 wt.% chromium, 19.24 to 20.87 wt.% molybdenum, 0.08 to 0.62 wt.% aluminum, less than 0.76 wt.% manganese, less than 2.10 wt.% iron, less than 0.56 wt.% copper, less than 0.14 wt.% silicon, up to 0.17 wt.% titanium, less than 0.013 wt.% carbon, and the balance nickel.

According to the embodiments provided herein, a system for intelligent vacuum control can include a prosthetic socket, an electric vacuum pump, one or more sensors, a non-transient computer readable medium, and a processor. The stiffness data can correspond to a relationship between pressure variation of the internal pressure of the prosthetic socket and the relative socket motion of the prosthetic socket. The processor can execute program instructions to automatically compare the data indicative of the relative socket motion of the prosthetic socket and the stiffness data. The processor can execute the program instructions to automatically determine a vacuum suspension range based upon the comparison of the data indicative of the relative socket motion of the prosthetic socket and the stiffness data.
