tissue (10-75 μm) [5]. The minimum pore size required to regenerate mineralized bone is generally considered to be 100 μm according to the study of et al [6]. Meanwhile, pore morphology, pore size... by the deformation mode of the individual cell struts, i.e. yielding, bending, and buckling, and the value of n is in a wide range of 1.0-6.3 [16]. YAMADA et al [17] suggested the value of n for the cell......
phenomenon during this process have been the point of focus. TANG et al [3] experimentally measured temperature distribution for a workpiece welded by FSW method. ZHANG et al [4] used a thermo-mechanical... of the FSW process. ZHANG et al [7] investigated the temperature rises, energy histories and material flows by application of a fully coupled thermo- mechanical finite element model in order to study......
的润湿时间(0.84 s)缩短了32%,润湿力为5.73 mN,较基体的润湿力提高了7.7%.温度升高,无论是基体还是复合钎料,熔体流动性增强,表面张力降低,最大润湿力增大,润湿时间大幅度缩短. 根据杨氏方程,当液态钎料在Cu片上的润湿达到平衡时(见图4[4]),有  ... free-lead solder alloy of Sn-Ag-Cu system[J].

. In the further rolling, the deformation pattern is as the same as the room temperature depending on the various slips. It agrees well with the result of KASCHNER et al [6] who said that twinning only... A A, JONAS J J. Use of Schmid factors to select extension twin variants in extruded magnesium alloy tubes [J].

are primarily consumed in stainless steel production and in super alloy or nonferrous alloy manufacturing, respectively [2]. Nickel laterite ores, which comprise 73% of the world’s proven nickel... by approximately 4.7% per year. Therefore, the recovery of nickel from laterite ores using pyrometallurgy has been extensively investigated. MICHAIL et al [7] investigated the microwave reduction of nickeliferous......
of Ni>Fe>Cu. LUO et al [9] observed the electrical conduction mechanism of nickel ferrite that Fe3+ is much more easily corroded by the electrolyte during electrolysis. The corrosion mechanism... alloy was better than that of the anode doped with Cu. 3.2 Preferential corrosion of Fe Table 1 shows the results of energy dispersive X-ray spectroscopy in the core and on the surface of the anode after......
melting process, which reduced possible evaporation losses at high temperature. First, a binary PdSi3 alloy was arc melted on a water-cooled copper hearth under a Zr-gettered Ar atmosphere from bulk pieces of 99.95% Pd and of 99.9999% Si (mass fraction). The button of PdSi3 alloy was co-melted with an appropriate portion of 99.99% Gd in a Hukin-type copper cold-crucible and cast into a 6 mm diameter......
