15 صفحه اولThe 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 Effects of Hydrogen Reduction on Magnetic Properties of Barium Ferrite Particles
A reduction process of the substituted Ba-ferrite has been found to be devided into three steps. At the first and second steps, the magneto-plumbite structure maintains and the coercivity increases. When the reduced-substituted Ba-ferrite particles are reoxidized, the coercivity is reversible in the first step but irreversible in the second step. During the third step, the magneto-plumbite stru...
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 ...
متن کاملMillimicrosecond Magnetization Reversal in Thin Magnetic Films
From ferromagnetic resonance xperiments and from calculations based on the modified Landau-Lifschitz equation, switching times for the coherent rotation of the magnetization in thin, permalloy-type films have been predicted to lie in the range of 1 mi1limicrosecond.l First measurements by D. 0. Smith et a1,2 utilizing a travellingwave oscilloscope with a response time of 2 mpec, indicated swi...
