1Microstructures and Hardness Properties for β-Phase Ti-24Nb-4Zr-7.9Sn Alloy Fabricated by Electron Beam Melting显示文摘Atomized,pre-alloyed Ti—24Nb—4Zr—7.9Sn(wt%) powder was used to fabricate solid,prototype components by electron beam melting(EBM).Vickers microindentation hardness values were observed to average 2 GPa for the precursor powder and 2.5 GPa for the solid,EBM-fabricated products.The powder and solid product microstructures were examined by optical and electron microscopy.X-ray diffraction analyses showed that they had bcc β-phase microstructure.However,it was found by transmission electron microscopy that the EBM-fabricated product had plate morphology with space ~ 100—200 nm.Although the corresponding selected area diffraction patterns can be indexed by β-phase plus α '-martensite with orthorhombic crystal structure,the dark-field analyses failed to observe the a'-martensite.Such phenomenon was also found in deformed gum metals and explained by stress-induced diffusion scattering due to phonon softening.J.Hernandez S.J.Li E.Martinez L.E.Murr X.M.Pan K.N.Amato X.Y.Cheng F.Yang C.A.Terrazas S.M.Gaytan Y.L.Hao R.Yang F.Medina R.B.Wicker 2013Journal of Materials Science & Technology2013,29,11:8

4On q-n-gonal Klein Surfaces显示文摘我们认为代数学的类 p ≥的合适的克莱因表面 X 是 2,有有商空间 X/ 的主要顺序 n 的自守φ < 代数学的类 q 的φ < 。这些克莱因表面被称为 q-n-gonal 表面,他们是代数学的类 q 的表面的表 n 的封面。在这篇论文,我们扩大已经学习的盒子 n ≤的结果 3 到这种更一般的状况。给 p ≥ 2,我们获得为各主要的 n,(可被考虑) 为哪个在那里存在的价值 q 代数学的类 p 的 q-n-gonal 表面。而且为每 p 并且为各可被考虑的 q,与代数学的类 p 检查 q-n-gonal 表面的所有拓扑的类型是可能的。几个例子被给:q 五角的表面和 q-n-gonal 与拓扑的类 g = 毗邻表面 0,1。B.ESTRADA R.A.HIDALGO E.MARTINEZ 2007Acta Mathematica Sinica,English Series2007,23,10:0
