Adjusting the microstructure through deformation process is one of ways to improve properties Mg alloys. Most studies have focused on influence after treatment mechanical In this paper, extruded and forged Mg-Gd-Y-Nd-Zr alloys were selected investigate corrosion performance two deformed magnesium immersed in 0.6 M NaCl solution using a hydrogen evolution test, weight loss an immersion experiment, electrochemical test. The results showed that WE43 undergoing different treatments presented...
Abstract As an important method for preparing aluminum foam, space holders have the advantages of simple preparation process, controllable porosity, high operation safety, easy to realize large-scale production and so on. In this paper, sodium thiosulfate (Na 2 S O 3 ) is selected as new raw material spacer replace traditional (such urea salt), which prepared by melting, injecting into mold solidifying. Three kinds spherical with different diameters were modified, foams three porosity (65%,...
Aluminum foam that is lightweight with high specific strength, energy absorption and other characteristics can be used in aerospace, transportation, machinery manufacturing fields. The PCM method usually to prepare closed-cell aluminum foams. microsized foams made by this process solve the non-uniform pore structures caused liquid drainage during foaming of large surface morphology internal structure are affected quality precursor for foaming. In paper, foamable precursors were obtained via...
A layered gradient aluminum foam was prepared by powder sintering with sodium thiosulfate (Na2S2O3) particles as the cell-forming agent. By cutting, polishing and observing under a microscope, it found that were not completely melted after but only combined surface melting. Based on quasi-static compression test macroscopic diagram of sample during deformation, mechanical properties studied, their deformation characteristics mechanism analyzed discussed.
Particle addition is an important method to prepare foam metal, and it of great significance clarify the mechanism particle stabilizing liquid metal foam. In this paper, ethanol-water solution system used simulate melt By changing wettability particles adjust distribution position in foam, two types with different are added, which mixed optimized a certain proportion improve stability as much possible. The main that large wetting angle at gas-liquid interface slow down gas migration, while...
Ultrathin CuCoAl nanosheets derived from layered double hydroxide (LDH) precursor (1-3 cationic-layers) were successfully synthesized by aqueous miscible organic solvent treatment (AMOST) strategy and performed for ethanol higher alcohols production via CO hydrogenation. The ultrathin (CuCo-LDH-aw) demonstrated a comparatively total (ROH) selectivity of 47.6%, the molar fraction reached up to 37.5% among alcohols. As revealed XRD, HRTEM, SEM, BET AFM characterizations, uniform dispersion...
The space holder method, a kind of powder metallurgy method which can avoid the process melting metal to prepare foams, has particular significance in solving difficulty preparing foams with high points. In this paper, Na2S2O3·5H2O, novel holder, was used aluminium foam and copper foam, were then test heat dissipation performance foams. We first prepared two kinds cell structures for (spherical composite cells) then, we compared performances their dissipation, it found that both spherical...
Given to the incomparable advantages in topology optimization, lattice structure into component individual customization, selective laser melting (SLM) has attracted extensive attention from many industrial sectors, such as, aerospace, defense and biology. In this work, Al/quasicrystal composite samples with several cellular sizes ranged from1.5 mm 5 mm were manufactured via using melting. The porosity of designed sample is all fixed as 50%. morphology QC reinforcement on top surface changes...
