| 1. | The study of thermal fatigue resistance of spheroidal graphite cast iron and cast steel 球铁与铸钢的抗热疲劳性能的比较 |
| 2. | An indentation - quench test was introduced to evaluate the thermal fatigue resistance 应用压痕-淬火法来评价材料热疲劳性能。 |
| 3. | Effect of strength and deformation of die steel deposited metal on thermal fatigue resistance 多层膜中巨磁电阻效应及与微结构的关系 |
| 4. | The results indicated that the microstructure , mechanical properties , oxidation resistance , growth resistance and thermal fatigue resistance were improved obviously 结果表明,显微组织、抗氧化、抗生长及热疲劳抗力等性能,均有显著的改善和提高。 |
| 5. | The second , chapter 4 assesses the effect of the content of tic on the thermal shock resistance of composites , and chapter 6 assesses the effect on the thermal fatigue resistance of composites 其次,第四章评价了tic含量对al _ 2o _ 3 - tic复合陶瓷抗热震性能的影响;而第六章评价了其对抗热疲劳性能的影响。 |
| 6. | At first , by controlling the adding of al2o3 and tic starting powder size , chapter 3 assesses the effect of al2o3 and tic starting powder size on the thermal shock resistance of composites , and chapter 5 assesses the effect on the thermal fatigue resistance of composites 首先,本课题通过al _ 2o _ 3和tic起始粉末粒径的控制,在第三和第五章具体讨论了其对复合陶瓷抗热震和抗热疲劳性能的影响。 |
| 7. | The thermal fatigue resistance of al2o3 - 20wt . % tic is the best , it is due to high kic and pore of the material . the pore decrease the stress extension of tip of cracks and delay themal shock fatigue cracks extension . 4 含20wt . tic的复合陶瓷具有高的k _ ( 1c )和较多的孔隙,这些空隙在热震疲劳时降低热震疲劳裂纹尖端的应力集中并阻碍裂纹扩展从而提高了材料的断裂抗力,故其具有最好的抗热疲劳性能。 |
