| 4. | 4 . the principle of the experiment including the isdg method is introduced . and the effect of shape and distance of the indention on strain measurement is analyzed 4 )介绍试验设备的组成及试验原理,通过理论推导和有限元数值模拟分析了拉伸试样的凹痕标记对应变测量的影响,对isdg ( interferencestrain displacementgauge )方法进行了深入的研究。 |
| 5. | Quite notable { 11 22 } twins with the appearance of strip piercing through lamellar colony were found in the tensile microstructure of ct20a alloy by tem analyzing , while no deformation twinning was found in the microstructure of alloy with high oeq Ct20a合金低氧当量拉伸试样的tem组织中有相当数量的{ 11几}型孪晶存在,孪晶在形貌上表现为穿过几个片的细条。高氧当量试样中没有观察到变形孪晶的存在。 |
| 6. | The relative density of the sample has reached as high as 97 . 4 % of fully dense . the mean micro hardness has reached hv496 . 3 . the fractography of the fracture section of the tensile sample was characteristic of dimple typically which indicated that the fracture belong to ductile fracture ;试样相对密度可以达到理论值的97 . 4 ;硬度方面由于激光立体成形工艺的特点,最后几层的硬度比开始时的高,平均硬度达到了hv496 . 3 ;拉伸试样的断口形貌具有典型的韧窝特征,属于延性断裂。 |
