A Fractographic Investigation of Explosively Fragmented Silicon-Manganese Steels by Scanning Electron Microscopy

The influence of microstructure upon fracture mode and relative fragmentation performance of steel test cylinders was assessed fractographically by scanning electron microscopy. For the compositions used in this study, a microstructural constituent which provides a path for brittle fracture under dy...

Description
Summary:The influence of microstructure upon fracture mode and relative fragmentation performance of steel test cylinders was assessed fractographically by scanning electron microscopy. For the compositions used in this study, a microstructural constituent which provides a path for brittle fracture under dynamic conditions appears to be a necessity for enhanced fragmentation.
