摘要：
Gradients in mechanical and fracture properties of SA-533B steel welds were studied using ball indentation technique. The local stress-strain behaviors of different microstructural zones of the weld were determined at various temperatures. Gradients in the strength of the base metal, weld metal and the different positions in the heat affected zone were observed to be consistent with the changes in the microstructure. The maximum in yield and the corresponding minimum in indentation energy to fracture occurred at around 1 mm from the fusion line. (C) 1999 Elsevier Science Ltd. All rights reserved.
