Nitrogen has been proposed to replace argon in vacuum furnaces for solution treating corrosion-resistant and precipitation-hardening alloys. Nitrogen costs less and allows treatment with a less-expensive vacuum furnace design. A qualitative examination of the tendency of materials to absorb nitrogen during solution treatment in vacuum furnace is described. The materials studied include two-corrosion resistant alloys and one precipitation-hardening alloy. Also, 4140 low-alloy steel was included as a control sample. The alloys were treated under conditions representing normal solution treatment for the precipitation-hardening alloy.
