摘要：Three weld metals with different oxygen contents were developed. The influence of oxygen contents on the microstructure and impact toughness of weld metal was investigated through high heat input welding tests. The results showed that a large number of fine inclusions were formed and distributed randomly in the weld metal with oxygen content of 500 ppm under the heat input condition of 341

delicious什么意思kJ/cm. Substantial cross interlocked acicular ferritic grains were induced to
generate in the vicinity of the inclusions, primarily leading to the high impact toughness at low temperature for the weld metal. With the increa of oxygen content, the number of fine inclusions distributed in the weld metal incread and
beginningthe grain size of intragranular acicular ferrites decread, which enhanced the
impact toughness of the weld metal. Nevertheless, a...
