Abstract

Promoted ignition-combustion has been used to describe a situation in which a substance with low oxygen compatibility ignites and supports the combustion of a more combustion-resistant material. Previous work has been reported on the investigation of this phenomenon as it relates to carbon steel, stainless steels and a number of significant engineering alloys in the nickel, cobalt and copper families.

Reported in this paper are the results of promoted ignition-combustion tests of wrought nickel alloys, cast nickel alloys and nickel alloy weld filler metals in oxygen atmospheres at pressures up to 34.5 MPa. The specific alloys tested were: CX2MW, CW2M, Hastelloy C-4, Hastelloy X, Inconel 601, Inconel 617, Inconel Welding Electrode 117, Inconel Welding Filler Metal 82 and 602CA.
