Determination of the Transverse Properties of Textured ESR 4340 Steel
Abstract
The objective of the current investigation was to determine the transverse properties of electroslag remelted AISI 4340 which had been processed to produce an intense (112) + (111) type texture. The material was processed from 10 inch (250 mm) x 5.0 inch (125 mm) x 5.0 inch (125 mm) thick slabs to approximately 0.5 inch (12.5 mm) thick plate in a two high rolling mill to produce the above texture. Utilizing the double ligament test; long transverse, short transverse, longitudinal and diagonal mechanical properties were determined. The results of the tests indicate that some anisotropy does exist in the plane of the plate. The associated levels of longitudinal yield stress and ultimate stress are considerably higher than those of a non-textured material of corresponding longitudinal ductility and hardness level (approx. H sub RC 57). The long transverse and short transverse ductilities are, however, lower than those of the non-textured material. In the case of the short transverse properties, both inferior strength and ductility were observed. The associated scanning electron microscopy showed the presence of minute flattened strip-like MnS inclusions on the macroscopically flat or terrace type fracture surfaces associated with the low ductility short transverse specimens. All of the specimens concerned with this orientation broke at stresses below the level of general yielding.
