This appears to be the result of the inability of the Varestraint test to account for crack “healing” during the final stages of solidification. Alloy 625 was found to be the most susceptible to solidification cracking, but this result is in conflict with fabrication experience. Thermocalc® simulations discovered that Fe and Cu are broadening the solidification interval of the new alloy, which favors the formation of hot. However, this alloy offers poor castability due to the formation of hot cracks. on the fatigue crack growth of 2205 duplex stainless steel welds. The new alloy Ti 6Al 2Fe 1Mo 0.9La 0.5Cu was developed out of the Ti 6Al 4V alloy and exhibits free-machinability.

Correlation among measured and simulated temperature ranges, and SCTR was poor for Hastelloy alloys X and W. and then compared to equilibrium of phases predicted by ThermoCalc simulation. These two filler metals exhibited the best resistance to weld solidification cracking. Good correlation among the simulated and measured solidification temperature ranges, and SCTR values were found for the 617 and 230W filler metals. may result in calibration of ThermoCalc and DICTRA models to predict oxidation. This temperature range was then compared to the equilibrium solidification temperature range derived from Calphad-based ThermoCalc™ calculations, Scheil-Gulliver solidification simulations, and in-situ measurements using the single sensor differential thermal analysis (SS-DTA) technique. Figure 2-22 SEM Image of Coating Cracks in Pt-Modified NiAl Diffusion. The alloys tested included Inconel 617, Inconel 625, Hastelloy X, Hastelloy W, and Haynes 230W.* Susceptibility was quantified by determining the solidification cracking temperature range (SCTR) which is a direct measurement of the range over which cracking occurs. The weld solidification cracking susceptibility of several solid-solution strengthened Ni-base filler metals was evaluated using the transverse Varestraint test.
