; at the same time,a significant amount of annealing twins and stacking faults were observed by TEM. Mechanical twins played a dominant role in deformation and as a result the mechanical properties were found...Effects of annealing temperature on the microstructure and properties of the 25Mn-3Si-3Al TWIP steelZhen-li Mi,Di Tang,Hai-tao Jiang,Yong-juan Dai,and Shen-sheng Li National Engineering Research......
Influence of Annealing Conditions on Nanocrystalline and Ultra-Soft Magnetic Properties of Fe75.5Cu1Nb1Si13.5B9 AlloyKazi Hanium Maria2,Shamima Choudhury22. Department of Physics,University of Dhaka... with the increase of annealing temperature.Their temperature dependence reflects the characteristic annealing temperature evolution of the basic magnetic parameters in these nanocrystalline......
of annealing temperature and time on microstructure and microhardness of Co41Ni2Fe20Ta5.5B26.5Si5 amorphous alloy have been investigated. Microhardness of the as-cast alloy is found to be 1170 HV. The maximum.... It is also observed that increasing the annealing time results in the decrease in microhardness values because of the increase in particle sizes of the precipitates.关键词:......

Sensitivity of coercivity and squareness factor of a Nd-Fe-B sintered magnet on post-sintering annealing temperature梁乐1,武梦艳1,刘丽华1,马冲1,王静1,张江东2,张澜庭11. School of Materials Science and Engineering... properties upon post-sintering annealing. Phase transformation of as-sintered magnet was investigated by differential scanning calorimetry(DSC). Three low temperature eutectic transition points were......
temperature and time reached 723 K and 90 min, Ni and Fe atoms markedly diffused into the Au layer. The grain size of the Au layer did not change markedly with the annealing condition. As the annealing time was 30 min and the annealing temperature exceeded 573 K, the resistance of the bilayer film increased with increasing the annealing temperature. Furthermore, the resistance of the bilayer film......
