(2017) 24: 296-302 DOI: 10.1007/s11171-017-3430-7 Analysis of strain variation in cross shear zone of plate during snake hot rolling ZHANG Tao(张涛)1, 2, 3, WU Yun-xin(吴运新)1, 2, 3... of the plate are analyzed. The length of cross shear zone is defined to have a better understanding of the deformation characteristic in cross shear zone, which is the essential difference from......
Structural, microstructural, and thermal characterizations of a chalcopyrite concentrate from the Singhbhum shear zone, IndiaRitayan Chatterjee1,2,Shamik Chaudhuri1,Saikat Kumar Kuila1,Dinabandhu...(FTIR, Raman, UV-visible) of the concentrate supported the XRD findings, and also revealed a marginal oxidation of the sulfide phase. The energy band gap of the sulfide was found to be 3.4 eV......
Transient Liquid Phase Bonding of IN738LC/MBF-15/IN738LC:Solidification Behavior and Mechanical PropertiesB.Binesh,A.Jazayeri Gharehbagh摘 要:Transient liquid phase(TLP) bonding of IN738 LC superalloy was carried out using a rapidly solidified MBF-15 Ni-based foil. The effects of bonding temperature(1130–1170 °C) and time(5–120 min) as well as foil......
affected zone 1 Introduction Ti2AlNb-based alloys have received considerable attention after the first report on the orthorhombic phase with stoichiometric composition close to Ti2AlNb in Ti-Al-Nb alloy... with the largest solubility is one major reason for the largest oxygen-enriched zone, and the highest lattice parameter of O phase is conducive to diffusive mass transfer. 4 Conclusions 1) Oxidation......
