Brittle Ductile Transition

Brittle-ductile transition (BDT) behaviour was investigated in low carbon steel deformed by an accumulative roll-bonding (ARB) process. The temperature dependence of its fracture toughness was measured by conducting four-point bending tests at various temperatures and strain rates. The fracture toughness increased while the BDT temperature decreased in the specimens deformed by the ARB process. Arrhenius plots between the BDT temperatures and the strain rates indicated that the activation energy for the controlling process of the BDT was not changed by the deformation with the ARB process. It was deduced that the decrease in the BDT temperature by grain refining was not due to the increase in the dislocation mobility controlled by short-range barriers. Quasi-three-dimensional simulations of dislocation dynamics, taking into account of crack tip shielding due to dislocations, were performed to investigate the effect of a dislocation source spacing along a crack front on the BDT. The simulation indicated that the BDT temperature is decreased with decreasing in the dislocation source spacing. Molecular dynamics simulations revealed that moving dislocations were impinged against grain boundaries and were reemitted from there with increasing strain. It indicates that grain boundaries can be new sources in ultra-fine grained materials, which increases toughness at low temperatures.

A materials test program was developed to measure mechanical properties of ASTM A285 Grade B low carbon steel for application to structural and flaw stability analysis of storage tanks at the Department of Energy (DOE) Savannah River Site (SRS). Under this plan, fracture toughness and tensile testing are being performed at conditions that are representative of storage tank conditions on steels that span compositions within ASTM A285 specifications. The testing is being done within the framework of a statistical test matrix and the data collected will be used to develop a predictive model for materials properties. The results presented herein are limited to a subset of data comparing for comparison of a recent vintage steel versus an older steel for fracture resistance behavior. These preliminary results indicate that dynamic loading rates result in a greater increase in the fracture toughness response in the case of the recent vintage steels of lower carbon content when compared to the archival heat of high carbon content. In addition, ductile tearing in the archival, high carbon steel was more likely to be interrupted by cleavage fracture at lower fracture energies than the modern, low carbon steel.

In order to study the mechanical properties of low-carbon steel under the coupling effect of the overall environment and the loads, the tensile mechanical test was carried out. The results indicated that, as the sea water concentration and tensile deterioration increased, both the mass-loss rate and surface roughness of the low-carbon steel gradually increased, and the yield strength, tensile strength, elongation, and section shrinkage decreased gradually. The mechanical parameters of the low-carbon steel were affected by the joint actions of the sea water concentration and tensile deterioration. The established mechanical model of low-carbon steel under the marine engineering environment shows that tensile deterioration had no effects on the fracture toughness, while the increase of sea water concentration could reduce the fracture toughness remarkably.

Machining Characteristics

Abstract AISI 1118 is a low carbon steel containing relatively high manganese and sulfur to provide free-machining characteristics. It is resulfurized coarse-grain type of steel. AISI 1118 is commonly used to produce carbunized components and parts but can be used without carburizing for some applications that do not require a hard surface. Among its many uses are bushings, gears, pins, shafts, and nuts and bolts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining. Filing Code: CS-91. Producer or source: Carbon steel mills. See also Alloy Digest CS-55, August 1974.
