Effect of Cold Rolling sequence on the Texture Development and Magnetic Loss of Grain Oriented Electrical Steels
Electrical steels are important alloys widely used in electrical instruments. The magnetic properties and low core loss of grain oriented silicon steels are closely related to the sharpness of Goss texture ({110} ).The direction of is the softest direction for magnetism. In this work, the microstructure and dependence of orientation density along the major texture fibers on the applied cold ro...

متن کاملMicrostructure evolution and abnormal grain growth during copper wafer bonding
Evolution of microstructure morphologies and grain orientations of Cu-Cu bonded wafers during bonding and annealing were studied by means of transmission electron microscopy, electron diffraction and X-ray diffraction. The bonded Cu grain structure reaches steady state after post-bonding anneal. An abnormal (220) grain growth was observed during the initial bonding process. Upon annealing, the ...
متن کاملLinear bubble model of abnormal grain growth
A linear bubble model of grain growth is introduced to study the conditions under which an isolated grain can grow to a size much larger than the surrounding matrix average (abnormal growth). We first consider the case of bubbles of two different types such that the permeability of links joining unlike bubbles is larger than that of like bubbles (a simple model of grain boundary anisotropy). St...
متن کاملEvaluation of the Austenitic Grain Growth by Thermoelectric Power Measurements
The influence of the deformation grade on the recrystallised grain size has been studied in the AISI 304 stainless steel. Therefore, cold rolled samples of this material with reductions varying between 30% and 80% were annealed at different temperatures and subsequently quenched. The mean austenitic grain sizes were measured and compared. Moreover, the correlation between the variation of the t...
