; Abstract: Composite materials having lamellar structure are known to have a good combination of high strength and ductility. They are widely used... nano-sized grains, high dislocation density and amorphous regions. From the results obtained, it is concluded that heavy cold drawing technique is an effective method for lamellar composite to get high......

, V, Nb, Ta and Ti. The possibility of producing a thermally compatible composite of MoSi2 and the C40 disilicides is discussed by critical assessment of MoSi2-TSi2(T=Cr, V,Nb,Ta, Ti) pseudo-binary phase diagrams. Relative phase stability between the CIIb MoSi2 and the C40 TSi2 is investigated and lamellar MoSi2/TSi2 two-phase microstructures are obtained by appropriate choice of composition......
A NUMERICAL MODEL OF LAMELLAR SPACING OF Al-Si EUTECTIC L.Xiao1,W.Q.Zhang1 (1.School of Mechanical Engineering,Liaoning Technical University,Fuxin 123000,China) Abstract:A numerical model... growth rate causes an in-crease of undercooling but a decrease of lamellar spacing,while increasing temperaturegradient leads to a decrease of lamellar spacing.The computed results......
Effect of La3+ on evolution of TiO2 coating layers on lamellar sericite and their pigmentary properties REN Min(任 敏), YIN Heng-bo(殷恒波), LU Zhang-zhun(卢章准), GE Chen(葛 晨), WANG Ai-li(王爱丽), YU Long... prepared by the chemical deposition method starting from lamellar sericite and TiCl4 in the presence of La3+. After calcination at 900 ℃ for 1 h, the resultant TiO2 nanoparticles on the sericite surfaces......
led to the degradation of the lamellar structure. While in the composite, lamellar structure remained relatively stable even after aging at 900 °C for 100 h. No breakdown of α2 lamellae except... at the α2/g interface which played an important role in retarding the coarsening of lamellar microstructure in the matrix of composite. Key words: TiAl composite; Ti2AlN; microstructure stability; lamellar......
Oxidation behavior of Fe40Al-xWC composite coatings obtained by high-velocity oxygen fuel thermal spray XIANG Jun-huai(向军淮)1, 2, 3, ZHU Xing-he(朱星河)1, CHEN Gang(陈 钢)1, DUAN Zhi(段 智)1... into the oxidation behavior of the as-deposited coatings at 650 ℃ under 0.1 MPa flowing pure O2. The present results show differences in the oxidation behavior of Fe40Al coating and Fe40Al-xWC composite coatings......
by tensile testing. The experimental results show that lamellar structure is composed of pores and SiCp clusters and can be improved by secondary processing, enhancing mechanical properties. The main strengthening mechanism and fracture behavior of MMCs were discussed too. Key words: spray co-deposition; SiCp/8009Al composites; lamellar structure; porosity; secondary processing  ......
