當樣品的厚度在30-60mm范圍時,模量值和硬度值的變化很小,分別在70GPa和50hv左右。 When the thickness of the sample was the range of 30-60mm, hardness and modulus values change slightly, and the data range of hardness and modulus was 70GPa and 50hv respectively. 已知圖2中的缺陷率,則通過圖2可以計算出整個樣品的缺陷率為7.8%,同理,本文計算了具有不同厚度比的樣品的缺陷率,見圖3,由圖3可知,厚度比越大,則缺陷率越高,且缺陷率在3.0%-9.8%之間。 It can be calculated that the entire sample defect rate was 7.8% through Figure 2 in which the defect rate was known. Similarly, the sample defect rate with different thickness ratio was calculated shown in Figure 3. The larger thickness ratio was corresponding to higher defect ratio and the internal friction peak temperature varied within the range of 150-300 °C. |

With thickness within the rage of 30-60 mm, the samples hardness and modulus displayed a slight variation around 70 GPA and 50 hv, respectively. The defect rate of the entire sample was 7.8% (Fig. 2). Furthermore, the defect rate of the sample with different thickness ratio was calculated separately (Fig. 3),indicating that the defect rate of the sample get higher, within the rage of 3.0%-9.8%, as their thinness get larger. 專業(yè)跨度有點大,慎重采用。 |
