- Summary:
-
Weld metal deposited using MIL-E-10018-M1 electrodes maintains very good fracture resistance, despite being comprised of a seemingly deleterious microstructure which includes extensive networks of pro-eutectoid grain boundary ferrite in the as-deposited weld metal and brittle martensite-austenite particles in the intercritically reheated weld metal and heat affected zone. To reconcile this contradictory structure-property relationship the report focuses on the fractography and metallography of a MIL-E-10018-M1 multipass weld, fractured during an explosion bulge test. Martensite-austenite particles identified in the intercritically reheated weld metal and heat affected zones were found to play no part in the fracture process. Pro-eutectoid grain boundary ferrite was shown to be the preferred fracture path in the as-deposited weld metal however, it does not substantially reduce the overall fracture resistance of the multipass weld metal. The very good fracture resistance of this weld metal is attributed to the interlocking grains of acicular ferrite contained within the prior-austenite grains and the relatively low volume fraction (18%) of as-deposited weld metal in the mulitpass weld. int
