The Discovery of Lower Acicular Ferrite
There is general agreement that a weld microstructure primarily containing acicular ferrite will exhibit high strength and excellent toughness due to its small grain size, high dislocation density, and the way in which the plates are dispersed in the microstructure (Pargeter, 1983; Sneider and Ken, 1984). In contrast, the presence of allotriomorphic ferrite, ferrite plates with aligned carbides...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Effect of Acicular Ferrite on Cracking Sensibility in the Weld Metal of Q690+Q550 High Strength Steels
High strength steels Q690+Q550 were welded using three different welding wires without preheating by gas shielded arc welding process. Microstructural characteristics of weld metals and nucleation mechanism of acicular ferrite were investigated by means of scanning electron microscope (SEM), energy dispersive spectrum (EDS) and transmission electron microscope (TEM). The straight Y-groove test ...
متن کاملEffect of plastic deformation on the formation of acicular ferrite
The effect of plastic deformation on the transformation of austenite to acicular ferrite in a Fe /Mn /Si /C alloy steel containing non-metallic inclusions was investigated. The transformation to acicular ferrite is retarded and the final fraction of acicular ferrite is reduced in plastically deformed austenite, which is a characteristic of a displacive transformation mechanism. The increase in ...
