Elevated-temperature tensile properties of ERNiCr-3 weld metal
The filler metal alloy designated by AWS Specification as ERNiCr-3 and commonly known as Inconel 82 has a nominal composition of 67 percent Ni-20 percent Cr-3 percent Mn-3 percent Fe-2.5 percent Nb and is used conventionally to join austenitic-ferritic dissimilar-metal joints. Tensile properties were determined for this alloy over the range 25 to 732/sup 0/C at strain rates of 3 x 10/sup -4/ and 3 x 10/sup -6//s. Specimens were taken from four different gas tungsten-arc weldments: three were 40-pass welds made between 19-mm-thick plates; one was a seven-pass weld between 13-mm-thick plates. Microprobe analyses of the two weldment geometries indicated that iron was the only element from the base metal that significantly diluted the weld metal. Considerably more dilution was found in the small weld than in the large one.
