摘要：
Intercellular segregation during the transformation of liquid weld metal to solid delta-ferrite has been related to centreline cold cracking in high strength low alloy steel weldments. The initiator of the centreline cold cracking has been shown to be solidification cracking as previously hypothesised. (c) 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
