6063-Al and 8011-Al alloys, respectively. BARATI et al [32] used two surface processing methods, i.e., FSP and modified friction stir vibration-assisted processing (FSVP) to fabricate surface... (HV 137) was observed in the SZ of FG sample because of a reduction in the size of the particles, leading to the even distribution of particles and thus enhancing the hardness values. The third pass......
, and the reduction of interfacial energy is left as the only driving force for re-melting. Furthermore, there is no phase transformation except for eutectic solidification in this alloy system. Consequently......
to 6 mol/L. And the other reason for the decrease of gold leaching efficiency was the reduction of removal efficiencies of arsenic and carbon. After the dust was successively leached by 15% H2SO4......
, the reinforced case obtains lower critical height ratios against the unreinforced case, with a reduction range of 2.4% to 8.5% due to the geomembrane effect. Indeed, the existence of reinforcement has......
reduction of the gear system by controlling the surface micro- topography. This paper is organized as follows. Section 1 summarizes the previous similar work, and concludes their deficiencies and objective......
alloys. The monovariant eutectics played a negative role in the resistance of hot tear formation while the LMP eutectics showed the opposite. (2) Reduction in the volume fraction of LMP eutectics......
and consolidated in a microwave sintering assisted powder metallurgy route. Finally, a comprehensive morphological, microstructural and mechanical as well as non-destructive characterization was performed... variations during ball milling of Al-2CNTs- 10Al2O3 nanocomposites modify the ultrasonic properties. Homogenous dispersion of CNTs and Al2O3 within Al particles, reduction of inter-particle spacing......
, the concentration of the directionality decreased, and the reduction improved the mechanical properties. The maintenance of the orientation indicates that the FSP mainly produced horizontal deformation... of China, 2019, 29: 2483-2495. [15] BARADARANI F, MOSTAFAPOUR A, SHALVANDI M. Effect of ultrasonic assisted friction stir welding on microstructure and mechanical properties of AZ91-C magnesium alloy [J......
to the thermodynamics of recrystallization, the reduction of interfacial and strain energy can promote the nucleation of DRXed grains [31-33]. This means that the regions containing large amount..., microstructure and mechanical properties of magnesium matrix nanocomposites fabricated by semisolid stirring assisted ultrasonic vibration [J]. Journal of Alloys and Compounds, 2011, 509: 8664-8669. [11] ZENGIN H......
on the reduction of variable pressure impact and the simplification of digital components as well as their control valve groups. Comparing with the literatures that have been studied, the main contributions......
