Zl. Gao et Kd. Zhang, COMPARISON OF THE FRACTURE AND FATIGUE PROPERTIES OF 16MNR STEEL WELDMETAL, THE HAZ AND THE BASE-METAL, Journal of materials processing technology, 63(1-3), 1997, pp. 559-562
The fracture toughness and fatigue crack growth rate of 16MnR steel we
ld metal, the HAZ and the base metal were measured. The fracture tough
ness J(1c) of the HAZ is lowest among the weld and base metals and the
HAZ, the J(1c) of the base metal being a little higher than that of t
he HAZ and that of the weld metal being the highest. The crack growth
in the HAZ is faster than those in the weld and the base metal, which
are nearly the same. Thus both the fracture and fatigue properties in
the HAZ are worse than those in both the weld and the base metals.
