Splitting,i.e., delamination behavior in Charpy specimens of low-carbon steel was found to be caused by cracks propagating between pancake grains parallel to the rolling plane of the as-rolled plate. The results suggest the mechanism is a decohesion of grain boundaries that is independent of the texture of the material. The number of splits increased with decreasing finishing temperature and impact test temperature. The energy absorbed in impact testing was inversely proportional to the number… 
Delamination Fracture Related to Tempering in a High-Strength Low-Alloy Steel
The delamination or splitting of mechanical test specimens of rolled steel plate is a phenomenon that has been studied for many years. In the present study, splitting during fracture of tensile and
Influence of Micro-Texture on Delamination of Hot-Rolled High Strength Low Alloyed Steel Sheets
We examined the effects of micro-texture and grain shape on the delamination of hot-rolled high strength low alloyed (HSLA) steel sheets through a series of uniaxial tensile tests. Prior to testing,
The Mechanisms by Which Splitting Occurs Along Sheared Edges and in Charpy Specimens of a 12% Chromium Steel
AbstractA study was made of the delamination or splitting behaviour in transverse Charpy specimens and along the sheared edges of 12-mm plate specimens of a low carbon titanium-stabilized 12%
Delamination of pipeline steels: determination of an anisotropic cleavage criterion
Cleavage fracture anisotropy has been studied on a ferrite-bainite low alloy pipeline steel plate. Mechanical tests have been performed on smooth and notched bars taken along the three principal
Cleavage delamination in impact tested warm-rolled steel
Cleavage delaminations or separations have been observed on fracture surfaces of impact specimens made from rolled steel pipe and plate products. These delaminations appear as cleavage cracks lying
On the analysis of delamination fractures in high-strength steels
The influence of the stress state on the occurrence of delamination during tensile testing has been examined in two high-strength steels. The stress state was varied by either machining notches into
Occurrence of non-metallic inclusions in 3CR12 steel and their effect on impact toughness
AbstractThe impact toughness and microstructure of a dual phase 12 wt-% Cr steel (3CR12) have been investigated. In particular, the occurrence of non-metallic inclusions has been studied in
Effect of Inclusions and Microstructural Characteristics on the Mechanical Properties and Fracture Behavior of a High- Strength Low- Alloy Steel
The strength and toughness properties of hot- rolled plates from three commercial heats of a highstrength low-alloy steel were investigated with respect to their intrinsic microstructural and
Recrystallisation, Structure, Texture and Properties of Pipe Steel Rolled at Wide Temperature Range
Methods of complex X-ray and metallographic analyses have been used to investigate the influence of texture, thin structure and grain boundaries of coiled low-alloyed steel for gas-and-oil pipeline
