They estimated 8 vol% of TiC nanoparticles in the nano surface composites. Yang et al. [196] used the scanning electron microscope (SEM) micrographs to estimate the volume fraction of reinforcement particles in high entropy alloy particle reinforced composites. The AlCoCrFeNi particles are ...

According to the principle of meso mechanics, the physical parameters X of granular composites can be calculated using the following formula $$ X = f_{1} x_{1} + f_{2} x_{2} , $$ (33) where \(f_{1}\) and \(f_{2}\) are the volume fractions of the enhanced phase and ...
This phenomenon could be attributed to the increasing local volume fractions of the reinforcement in the TiBw-rich network boundary: although the two TiBw/Ti6Al4V composites (65 μm and 150 μm) share equal overall volume fractions of TiBw, the local volume fraction of TiBw in...
Piezoelectric composites are optimised for maximum strain levels by simultaneously accounting for the concentration and orientation of the piezoelectric and polymer constituents. Existing studies in piezoelectric composites are confined to independently identifying either the optimal volume fraction or the ...
The objective of this paper is to enhance the quality and processing efficiency of 0.5 mm micro-hole in high volume fraction (55%) SiCp/Al7075 composites used for electronic packaging. Initially, an analysis is conducted on the trajectory of the variable step pecking drilling. Subsequently, a ...

The blue probe used has a 1 nm molecular diameter and a well-defined chemical formula, entering all the pores larger than 1 nm. However, the orange probe, obtained by condensation of 5-nitro-o-toluenesulfonic acid in an alkali solution, has a molecular diameter range of 5–36 nm. The or...
denote the density and volume fractions, respectively. The subscriptsmatandincrepresent the matrix and inclusion materials, respectively. Furthermore, the percentage porosity (\(\%P\)) or the volume fraction of voids (\({v}_{v}\)) of the composites were determined through the following formula...
A similar result can be also found in ref. 20, while the monolithic material is Ti and the volume fraction is 15 vol.%. Even when the composites are reinforced with low volume fractions of TiBw (3 vol.%) the creep time before fracture is twice the one of the monolithic alloy. The ...
