Abstract: Abstract Effective grain size is a direct indicator of the high angle grain boundary (HAGB) density of microstructures. A small effective grain size suggests a high density of HAGBs, which provide effective barriers to cleavage… read more here.

Abstract: In this study, the series temperature Charpy impact and drop-weight tear test (DWTT) were investigated, the misorientation angles among structural boundaries where the cleavage crack propagated were identified, and angles of {100} cleavage planes between… read more here.
