Hot tearing is one of the most severe and irreversible casting defects for many metallic
materials. In 2004, Eskin et al. published a review paper in which the development of hot …

Abstract Inconel 939 (IN939) suffers from cracking in the laser powder bed fusion based
additive manufacturing (LPBF-AM) process. Previous studies attempted to minimize the …

Laser welding of aluminum alloys can be associated with solidification cracking. The
severity of cracking in these alloys depends on various factors, such as the initial …

To better understand the influence of Fe-rich intermetallics on solidification defect formation,
fast in situ synchrotron X-ray tomographic microscopy experiments were performed on a …

Abstract Ti-1Al-8V-5Fe (Ti-185) and other Fe containing β-Ti alloys are attractive because of
their high strength and low cost. These alloys, however, cannot be produced through ingot …

The effects of Mg back-diffusion on liquid channel segregation and morphology, and hence
on the solidification cracking susceptibility (SCS) of Al-4.0 wt% Mg alloy, were investigated …

Hot tears can arise during the late part of alloy solidification because of the shrinkage of
isolated liquid as it turns to solid and may have a catastrophic effect on cast tensile …

The segregation and morphology of liquid channels at the last stage of solidification are
closely related to hot cracking formation. We use Phase-Field (PF) simulations to investigate …

The mechanical behavior of partially solidified Al–Cu alloys is investigated to assess the
influence of mushy zone deformation on hot tearing. For this purpose, the results of a semi …

High-speed observation of visible and infrared radiation was performed to measure the
molten pool geometry, velocity of the solid–liquid interface and temperature profile during …
