the base metal. The transformation behavior of the joint is affected by the vaporization of Ni during the laser welding process. The ultimate tensile strength of the joint is up to 70% of the base metal......
/DTG. The vaporization enthalpy of hafnium ethoxide was found to be 79.1 kJ/mol. The result confirmed that hafnium ethoxide was suitable for the preparation of hafnium oxide by atomic layer deposition...) Langmuir equation is used to calculate the vapour pressure and the vaporization enthalpy of hafnium ethoxide. The principle of using thermogravimetry to estimate the vapour pressure is based......
好;烧结方式对于Bi2O3挥发控制的强弱顺序为埋烧,盖烧,裸烧. 关键词:ZnO-Bi2O3压敏瓷;氧化锌;烧结;挥发 中图分类号:TB34;TN304.93 文献标志码:A Influence of sintering process on Bi2O3 vaporization of ZnO-Bi2O3 based varistor... samples exhibit better electrical properties. These results also show that Bi2O3 vaporization in three sintering processes is in the order from strong to weak as follows: sintering within a powdered bed......

℃, the oxidation resistance of Cr-rich Cr-Nb alloys decreases due to the continuous vaporization of CrO3 in the oxide scale. Therefore, it is necessary to apply surface protective coatings on Cr(or Nb)-NbCr2......
) on the evaporation-condensation behavior in thermosyphons was analyzed. The results show that this CFD model can reproduce both the vaporization and condensation processes well. The predicted......
