查询词典 mechanical

Firstly, it is difficult to densify CeO2 based solid electrolyte materials and a sintering temperature above 1600℃is required to prepare dense CeO2 based solid electrolyte materials by the conventional solid-state reaction method;Secondly, doped ceria are brittle materials and have weak mechanical strength, which would be susceptible to fracture due to thermal stresses and mechanical stresses during cell fabrication and operation; Thirdly, electronic conduction will be introduced because of the reduction of Ce4+ under low oxygen partial pressure, which would reduce the output voltage and output power of the cells.

其一，CeO_2基电解质材料难以致密化，用常规的固态反应法制备的CeO_2基电解质粉体需要在1600℃以上烧结才能达到致密化；其二，CeO_2基电解质为脆性材料，机械强度低，使其容易在电池的制造及运行过程中由于热应力及机械应力而破裂；其三，CeO_2基电解质在燃料极一侧由于Ce4+还原为Ce3+出现电子导电，降低电池的输出电压和输出功率，影响电池的性能。

By dilatometric change and microscopic test, the critical point at Ac1、Ar1、Ac3 and Ar3 of ML40Cr steel was detemined in Gleeble-3800 the thermal-mechanical simulator. The continuous cooling transformation diagram of ML40Cr steel was obtained by measuring the expanding curves of different cooling rates. The mechanical property and transformation of austenite were analyzed. The proper range of control cooling rate about ML40Cr cold heading steel was found. All those provide the reference for productive practice to develop cold heading steel.
