Development of the Strain-To-Fracture Test to Study Ductility-Dip Cracking in Austenitic Alloys
… been developed as a robust testing technique for ductility-dip cracking (DDC) and other elevated temperature cracking phenomenon. Samples are tested over a range of temperature and strain, producing temperature-strain cracking envelopes. Threshold strain for fracture (Emin) and the ductility-dip …

Elemental Effects of Fe, Mo, C, and Hf (or Nb) on Solidification Behavior, Microstructure, and Weldability of High-Cr, Ni-base Filler Metals
… mitigation of primary water stress corrosion and ductility-dip cracking in Ni-Cr-Fe base materials and filler metals has led to increased Cr, Nb, and Mo contents in these alloys, respectively. Nb additions however, have resulted in a significant increase in the solidification cracking …

High temperature cracking of nickel chromium austenitic steels.
… detailed classification of high temperature weld cracking is proposed. Two major types of cracking are recognised: Type 1 - separations along boundaries decorated with liquated second phase resulting from microsegregation, (solidification cracking in the weld metal and liquation cracking in the …

Investigation of Weldability in High-Cr Ni-base Filler Metals
… been affected by primary water stress corrosion cracking. During welding, defects may result from super-solidus and sub-solidus cracking phenomena. The ability to evaluate and quantify the degree to which a given alloy is susceptible to each cracking mechanism is of great importance in alloy …
