2粉体的研究 |
| 2. | Spheroidization evaluation standard of 12cr1mov steel used in power plant
火电厂用12cr1mov钢球化评级标准 |
| 3. | And the relationship between spheroidization efficiency and apparent density was also discussed
在适当的条件下可以得到球化率高、球形度好的粉体。 |
| 4. | The effect of feed rate and particle size on spheroidization efficiency was studied
用光学显微镜观察球化前后颗粒的形貌；用流动仪测定球化后粉体的松装密度。 |
| 5. | The results indicated that low graphite spheroidization rate and free cementite were the main causes of poor mechanical property
试验结果表明，控制碳当量和球化剂加入量，采用瞬时孕育等可提高球化率；采用预热砂型等可减少渗碳体。 |
| 6. | Excessive imperfections even sub - grained boundaries may be introduced in cementite . this makes the accelerating dissolution and spheroidization of cementite easy . 5
由于渗碳体的强烈塑性变形，在其内部导入了大量的晶体缺陷甚至亚晶界。 |
| 7. | The fracture and spheroidization of cementite shows obvious anisotropy . there are two possible mechanism about spheroidization of cementite : the fracture cementite lamellae grows up non - uniformly and the fine spherical cementite particles grows up as the core
渗碳体的破碎和球化表现出明显的各向异性。渗碳体的球化可能以两种机制进行：破碎渗碳体片的非均匀长大和细小球状渗碳体颗粒的形核长大。 |
| 8. | Liquid penetrant testing , eddy current testing and magnetic particle testing are mainly used in the detection of surface flaws and near - surface flaws , radiographic testing and ultrasonic testing are mainly used in the detection of inner defects , ultrasonic testing is also used in the detection of spheroidization quality of smooth surface castings , while vibration testing is used in the detection of spheroidization quality of rough surface castings
液体渗透检测、涡流检测和磁粉检测常用于检测铸件表面和近表面缺陷，射线检测和超声检测常用于检测铸件内部缺陷，超声检测可用于表面光洁铸件的球化质量的检测，振动检测则用于表面粗糙铸件的球化质量的检测。 |
