and the size varied slightly with different annealing temperatures. Pure cubic Y2O3:Eu3+ phase was formed and the size was the smallest at annealing treatment of 500 ℃. Under the annealing temperature below 500 ℃ its diameter increased with increasing annealing temperature, and remained in a stable size when the annealing temperature was above 500 ℃. The PL spectra of excitation spectra of Y2O3:Eu3......

The mechanical properties were measured by tensile testing, with their crystal orientations analyzed by X-ray diffraction (XRD). After the annealing treatment, the elongated grains were transformed......
the recovery, recrystallization and growth of grains. Additionally, the annealing temperature influences the magnetic properties more significantly than annealing time, and with the increase of heating-up... electrical steel effectively[2]. In this work, influences of annealing temperature, annealing time and heat-up rate on the microstructure and magnetic properties of cold rolled non-oriented......
one because of its good cyclic property and relatively high capacity with a plateau at around 4.7 V[13,16]. It is proved that the strategy of slowly cooling or annealing treatment at low temperature...] synthesized LiNi0.5Mn1.5O4 employing an annealing treatment at 700 ℃ in air after the high-temperature calcination at temperature as high as 1 000 ℃. WU et al[16] employed an annealing treatment at 600......
temperature. Moreover, it is revealed that the rate of heat transfer is an increasing function of radiation-conduction parameter. Key words: conjugate; radiation; conduction; transient annealing process Cite... during the annealing process, in a way that the temperature decrease from the surrounding heated walls toward the center of solid block can be clearly seen. If one compares the temperature fields......
