Journal ArticleDOI
Structure and mechanical properties of boron-rich boron carbides
TL;DR: In this article, the effect of boron/carbon ratios on the microstructure and mechanical properties of the complex material has been investigated and it has been found that excess boroni substitution gives rise to expanded lattice constants, orientational asymmetry of the chain structure and distortion of the icosahedra of rhombohedra B 4 C units.
Journal ArticleDOI
Precipitation of icosahedral phase from a supercooled liquid region in Zr65Cu7.5Al7.5Ni10Ag10 metallic glass
TL;DR: In this paper, the formation of icosahedral phase from the rapidly quenched Zr65Cu7.5Al7.10 metallic glass was confirmed and the kinetics of the precipitation upon isothermal annealing in the supercooled liquid region were examined by differential scanning calorimetry.
Journal ArticleDOI
Correlation between structural relaxation and shear transformation zone volume of a bulk metallic glass
TL;DR: In this paper, the effect of structural relaxation on shear transformation zones (STZs) in a Zr70Ni16Cu6Al8 glassy alloy was evaluated.
Journal ArticleDOI
Investigation of cutting force and temperature of end-milling Ti–6Al–4V with different minimum quantity lubrication (MQL) parameters
TL;DR: In this article, the effects of different MQL parameters (air pressure, quantity of minimum quantity lubrication (MQL) oil, position of the MQL system, etc.) have different effects on the milling force and milling temperature, which play significant roles in improving/reducing the cutting quality of a workpiece and extending/shortening the tool life.
