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 2025&#xb0; F. and 2100&#xb0; F., and then hot worked at start temperature between 2025&#xb0; F. and 2100&#xb0; F. 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.

Method for producing two-phase Ni&#x2014;Cr&#x2014;Mo alloys

Electrical conductor coated with a corona-resistant, multilayer insulation system comprising first, second, and third insulation layers. The first insulation layer is disposed peripherally around the electrical conductor, the second layer is disposed peripherally around the first layer, and the third layer is disposed peripherally around the second layer. The second layer is sandwiched between the first and second layers and comprises 10 to 50 parts by weight of alumina particles dispersed in 100 parts by weight of a polymeric binder.
