and liquidus temperatures,in the CaO-SiO2-Nb2O5-La2O3 quaternary system phase diagram has restricted the comprehensive utilization of the niobium(Nb) and rare earth(RE) resources.In this work,the phase......
">The flow curves of an ultra-high nitrogen austenitic steel containing niobium(Nb) and vanadium(V) were obtained by hot compression deformation at temperatures ranging from 1000°C to 1200°C and strain......
Effects of Nb on the microstructure and mechanical properties of 38MnB5 steelLi Lin1,2,Bao-shun Li1,Guo-ming Zhu1,Yong-lin Kang1,Ren-dong Liu21. School of Material Science and Engineering, University of Science and Technology Beijing2. Ansteel Technology Center摘 要:The effects of the microalloying element niobium(Nb) on the microstructure and mechanical......
of niobium,the hardness of the Cu-0.52vol.%Nb alloy arises slightly. The fibers formed by cold rolling be-come un-clear and un-straight and have less combination,and considerably more subgrains......
mechanical property tests were conducted.The Nb addition can effectively refine the prior austenite grains and microstructure of the steel.Fine niobium precipitates with a diameter of about 10–50 nm......
and elastic properties of niobium nitrides(NbN). The lattice parameters ao and c0/a0, elastic constants C ij, bulk modulus B0, and the pressure derivative of bulk modulus B0 ′ are calculated. The results......
">Accumulative roll bonded(ARB) Copper Niobium(Cu-Nb) nano-lamellar composite(NLC) panels were friction stir welded(FSWed) to evaluate the ability to join panels while retaining the nano-lamellar......
and liquidus temperatures,in the CaO-SiO2-Nb2O5-La2O3 quaternary system phase diagram has restricted the comprehensive utilization of the niobium(Nb) and rare earth(RE) resources.In this work,the phase......
, electron probe micro-analysis, scanning and transmission electron microscopy and mechanical testing. The results show that the sintered samples mainly consist of γ phase, O phase, niobium solid... (based on Ti2AlNb), niobium solid solution (Nbss) phase and B2 phase. The Nbss phase behaves in a ductile manner and provides significant toughening of the TiAl matrix, and alloys with a significant......
