| 1 | To develop a quantitative method for predicting shrinkage porosity in squeeze casting显示文摘In order to secure high strength and high elongation of suspension parts,it is critical to predict shrinkage porosity quantitatively.A new simulation method for quantitative prediction of shrinkage porosity when replenishing molten metal has been proposed for squeeze casting process.To examine the accuracy of the calculation model,the proposed method was applied to a plate model. | Shaomin Li Kenichiro Mine Shinji Sanakanishi Koichi Anzai | 2009 | China Foundry2009，6，1： | 2 |

| 10 | Quantitative evaluation of die casting surface defect severity by analyzing surface height显示文摘It is necessary in factories to assess the severity of the surface defects of castings, as a slight surface defect will be taken as qualified when it brings no bad effect or it can be removed by the subsequent processing. In practical production, professional technicians visually inspect the surface defect severity according to their individual experience. Therefore, it is difficult for them to maintain the same standard and accuracy in the subjective, tedious and labor-intensive work. Recently, image processing techniques based on optical images have been applied to achieve better accuracy and high efficiency. Unfortunately, optical images cannot directly quantify surface depth, which works as a crucial factor in the practical assessment of surface defect severity. The surface roughness evaluation algorithm, which takes into account of both area and depth information of the assessed surface, was applied to directly characterize surface defect severity based on surface asperity rather than optical image. The results using standard casting pieces show that surface defect severity has no apparent dependence on surface roughness. However, the subsequent results show that the root-mean-squared-deviation(RMSD) of surface gradient of flow line defects positively correlates with the increase of defect severity. The other types of defect do not present such tendency. Thus, practical workpieces with flow line defects on the surface were used to verify the universality of this tendency. The results show that surface roughness of an unqualified workpiece is larger than that of a qualified workpiece after surface slope adjustment, but presents no obvious coincidence before the adjustment. In contrast, the RMSD of an unqualified workpiece, no matter before or after the adjustment, is larger than that of a qualified one. | Yan Xu Naoya Hirata Koichi Anzai | 2017 | China Foundry2017，14，5： | 0 |
