Abstract: Ingots from casting processes usually contain defects such as voids from solidification. These voids can lead to failure during application, e.g., crack formation. Accordingly, it is important to close these voids in the forging process.… read more here.

DOI: 10.3390/met9030343
Abstract: The void closure mechanism during the roll-bonding process was investigated using a multiscale approach, which includes contact deformation at the macro-scale and atomic bonding at the micro-scale. The closure process of the voids was observed… read more here.
