Porous metals have been developed greatly and swiftly in recent years. In this paper, main types of these materials are described briefly, and their preparation
The tensile plastic deformation behavior of B2-ordered Fe3Al single crystals at room temperature was systematically investigated. The results show that the mech
The microstructural characteristic of 1070Al matrix composites reinforced by 0.15 μm Al2O3 particles whose volume fraction was 40% was investigated by TEM and
Based on sound absorption mechanism of material, the special sound absorption material CEMCOM for road sound insulation is introduced. This high sound absorptio
The compressive creep behavior at 1200~1400℃ of an in-situ synt hesized MoSi2-30%SiC (volume fraction) composite and a traditional PM MoSi2 -30%SiC (volume frac
A type of wavelet neural network, in which the scale function is adopted only, is proposed in this paper for non-linear dynamic process modelling. Its network s
