rate was further increased to 20℃/min. 10℃/min was the critical heating rate for obtaining high magnetic properties. The maximum values of Mr and Hci reached 0.70 T and 780.1 kA/m when the annealing...Effect of annealing process on magnetic properties of Sm(Co0.6Fe0.27Cu0.1Zr0.03)7.5 ribbons XUE Gang1,PENG Long1,ZHANG Huaiwu1 (1.State Key Laboratory of Electronic Thin Films and Integrated......
and TiO2[16], the resistivity of the films can be changed because heating resistors are utilized at higher temperatures. Therefore, we investigated the effect of O2 annealing on the resistivities..., the IrO2-TiO2 thin films showed minimal resistivity change even after O2 annealing process at 600 °C. Therefore, IrO2-TiO2 thin films can serve as a suitable heating resistor material for non-passivated thermal......
Abstract: The electrical resistivity of NZ30K-Mg alloy was measured at different heating rates during continuous heating to study the precipitation kinetics. Two kinds of metastable phases, β″ and β... the continuous heating, the samples were heated at a fixed heating rate until the phase transformation had finished. The heating rates of 0.10, 0.17, 0.55, 1.08, 2.30, 5.90 and 7.25 K/min were adopted......
