Abstract Vanadium-based alloy membranes with body-centred-cubic (BCC) structure are considered as one of the leading alternatives to Pd-based alloys for hydrogen separation applications due their lower cost and higher permeability. As permeability mechanical properties depend on what microstructure can be produced mainly by composition under same processing conditions, effect microstructure, has been investigated V 85 Ni 15 10 Ti 5 (at%) prepared a process route. All atoms dissolve into...
The effects of intensive melt shearing and Ca concentration on grain refinement commercial purity Mg have been investigated by standard TP-1 casting tests, X-ray diffraction combined with the observation optical microscope scanning electron microscope. It was found that, without shearing, addition greatly improved structure from columnar to equiaxed grain. With increasing 0.01 1 wt. %, average size alloy gradually decreased. When applied, structures remained variation. first decreased then...
The low concentration Zr and intensive melt shearing effects on grain refinement of commercial purity Mg has been studied. It was found that the addition, combined with shearing, resulted in a significantly refinement. mechanism dispersing MgO film into individual particle enhancing adsorption surface proposed.
The comparative studies of grain refinement commercial purity Mg by CaO/Ca addition have been investigated using TP-1 tests, optical microscope, XRD characterisation and TEM (STEM) observation along with EDX analysis. Experimental results showed that Ca/CaO significantly refines the structure Mg. Compared Ca addition, CaO exhibits finer size average remains invariable further addition. is readily reduced to melt forms Mg2Ca on surface MgO particles. First-principle calculations were used...
Circulating tumor cells (CTCs) are cancer that released from the original and circulate in blood vessels, carrying greatly similar constituents as tumor.
The first-principle calculation was used to understand new insight of Ca element refining grain structure in commercial purity Mg. Negative adsorption energy, strong ionic bond and negative shift partial density states verify that is readily adsorbed on the surface MgO. Combined with analysis interfacial bonding between Mg2Ca α-Mg, layer formed via efficiently nucleating α-Mg proposed. Adsorption other alkaline earth elements (Be, Sr or Ba) crystallographic feature Be, Mg17Sr2 Mg17Ba2 along...
First-principles calculation was carried out to investigate the mechanism of Zr poisoning Al-5Ti-B grain refiners via Ti (or Zr)-adsorbed TiB2 models. The results show that most energetically favourable sites for both adsorptions and are bridge- hollow-sites. calculated (i) adsorption energy is slightly more negative than Zr; (ii) distance with interface shorter (iii) number electric charges acquisition adsorbed about twice larger (iv) mixed metallic/covalent bonding on stronger interface....
The modifying influence of aluminium phosphide to the morphology primary Si and eutectic was investigated in hypereutectic Al-20Si alloys via adding Al-Cu-P master alloy (0.5, 1, 20 wt.%). Microstructural results showed when addition from 0 0.5%, phase decreases size remains invariable; higher than keeps invariable, increases. To prove nucleation effect AlP on phase, interfacial properties Si/AlP interface were using first-principles calculations. Results AlP(100)/Si(100) energy is between...
