Effect of B on the Microstructures and High Temperature Oxidation Resistance of a Nb-Si System In-situ Composite Aiqin Liua� Shusuo Li� Lu Sun, Yafang Han School of Materials Science and Engineering, Beihang University, Beijing 100083, China a laqyezi@163.com Key words: B, Nb-Si system in-situ composite, oxidation resistance Abstract: Nb-16Si-24Ti-6Cr-6Al-2Hf-xB(x=0, 0.5, 1, 2, 4, 6) in situ composites were prepared by arc-melting.
This may be resulted from several beneficial roles of boron, i.e., boron improves the resistance of Nb5Si3 by solid solution strengthening, inhibits the diffusion of oxygen in the matrix, improves the adherence between the oxide scale and the substrate and increases the cracking resistance of the oxide scale.� Introduction Nb-Si system in-situ composite has attracted much attention as the new promising high temperature structure material with significantly higher operating temperature than current generation advanced Ni-base superalloys [1-4].

The basic form of Cobb - Douglas production function, (1) Where Y represents the volume of output, K represents the amount of capital invested, L represents labor input, Ais parameter which economic meaning is general technological progress, namely, excluded factors of production, the factors have an important influence on volume of output, including technological advances, management level, structural adjustment, institutional change and so on.Under the same amount of capital and labor conditions, the larger of A, level of technology or production management level of the enterprise (or regional, national) is higher;α, β represent distribution parameters, its economic significance is,under other input factors remain unchanged situation,the increased percentage of output as the input of capital (or labor) elements increased every 1%, so called labor (or capital) of output coefficient of elasticity.

In civil engineering, polypropylene (PP) fibers are often utilized as a supplementary reinforcement in three dimensions, most commonly in asphalt.
This highlights the need for fundamental engineering material qualities that can lead to advantageous material characterization for permanently advanced material characterization for permanent deformation analysis [20].
