Effect of porosity on the electrical properties of Fe-based specimens fabricated by powder metallurgy

Abstract

ϭ 2s(V /I ) F [1] Effect of Porosity on the Electrical where F is the correction factor, which depends on the ratio Properties of Fe-Based Specimens t/s; in our experiments, t/s ϭ 1.33, and the F factor is equal

The Fabrication of Carbon Nanotubes Reinforced Copper Coating by a Kinetic Spray Process

“…Although the detailed reason has not been found, it might be related with the atomic diffusion at the inter-particles boundaries, which leads to structural inhomogeneities of large-sized pore distribution in the as-heat-treated coating. 16 As shown in Figure 2(b), the porosity along "vertical" direction was obviously lower than that of "horizontal" one after heat treatment, comparing with the homogeneous distribution of fine pores in as-sprayed coating (as shown in Fig. 2(a)).…”
