| 1 | Unique microstructure and thermal insulation property of a novel waste-utilized foam ceramic显示文摘A characteristic CaO-Al2O3-SiO2 based foam ceramic was prepared by melt-foaming with solid wastes as main raw materials.The similarity to sandwich hole wall microstructure of this novel thermal insulating material was presented and the relationships between this unique microstructure and porosity,density,thermal conductivity and strength were discussed.Comparing the measured and theoretical values with that of the traditional foam ceramic,it can be found that,for the matching of fine skeleton with hole wall,this original sandwich structure can reduce thermal conductivity and increase flexural strength effectively. | F.H.Kuang S.M.Wang C.Gao H.B.Zhang R.K.Ren J.L.Ren J.Tong Y.M.Liu | 2020 | Journal of Materials Science & Technology2020，47，13： | 5 |

| 3 | Stresses State and Mechanical Behaviors of the Green Body During Die Compaction and Ejection Process显示文摘Finite element simulations for metal powder compaction of a clutch plate were performed to examine the stresses during compaction,unloading,and ejection.To describe the mechanical behavior of compacted green body,a modified densitydependent Drucker-Prager Cap model was utilized to predict the stress and density distribution of the compacted clutch plate during loading and ejection stages.The results indicate that maximum tensile principal stress was a main driving force for the tensile crack initiation during ejection stage,and shear stress may be another driving force in both compaction and ejection stages for shear crack initiation.There were peak value of the stresses during ejection stage,and the stresses are in compressive state only during compaction stage.Therefore,the tensile crack initiation is not possible during compaction except shear crack.Hoop stress in the clutch plate is of less contribution to the crack initiation during compaction,unloading and ejection.Study of criteria of the crack initiation and fracture is necessary in order to obtain uniform density and crackfree components in the manufacturing of metal powder compaction. | S.M.Wang Y.Wang Y.X.Wang F.P.Liu J.Cao | 2020 | Acta Metallurgica Sinica(English Letters)2020，33，4： | 1 |
