TL;DR: A new powder manufacturing process for Ti and Mg metallic foams was proposed in this paper to design porosity, pore size, and morphology of open-cellular foams.

TL;DR: In this article, the mechanical properties of commercially pure (CP) Ti at room temperature were investigated and the decreasing grain size in CP Ti leads to significant increases in its hardness and/or strength.

TL;DR: In this article, multiwalled boron nitride nanotubes were synthesized under heating of chemically-vapor-deposited multiwalled carbon nanoteubes and borton trioxide to 1773 K over 30-60 minutes by induction currents in a flowing nitrogen atmosphere.

TL;DR: In this paper, it was shown that the alloys Co2Ni1−xGa1+x, x = 0.06, 0.09,0.12, and 0.15, are ferromagnetic shape memory alloys.

TL;DR: The microhardness and microstructural evolution during high pressure torsion testing in samples of pure nickel were investigated in this paper, where a detailed TEM and X ray study was used.

TL;DR: In this paper, the effect of grain size reduction on the wear resistance of electrodeposited nanoc-rystalline pure nickel coatings was investigated quantitatively by the Taber abrasive wear test, astandard test often applied in industrial testing.

TL;DR: In this paper, the microstructure of a pearlitic steel wire with a higher strain as much as 5.1 with tensile strength of 5,170 MPa was characterized.

TL;DR: In this article, a new sintering-dissolution process (SDP) was proposed for manufacturing net-shape, open-cell Al foams, characterising the porosity, microstructure and compressive properties of the foams produced under a range of SDP conditions.

TL;DR: In this paper, a low carbon steel plate of 1.5 mm thickness was used for the HESP treatment, where the entire surface of the sample to be treated is peened by the flying shots with a high energy.

TL;DR: In this paper, an abnormal strain rate effect on the tensile ductility was observed in an electrodeposited nanocrystalline (nc) Cu sample, in which the fracture strain increases significantly at higher strain rates (from 6 x 10(-5) to 1.8 x 10(3) s(-1)).

TL;DR: In this article, the formation of in situ TiB 2 via a chemical reaction among Al, TiO 2 and B 2 O 3 O 3 was investigated, and the formation was shown to increase the yield and ultimate tensile stresses of the composite reinforced with 15%TiB 2 compared to its unreinforced counterpart.

TL;DR: In this article, annealing temperature is found to significantly affect the superelasticity of NiTi shape memory alloy, and the plateau strain of the forward stress-induced transformation increases with increasing annesaling temperature, being 9% for specimens annealed at 600°C.

TL;DR: In this paper, a pre-ECAP solid-solution treatment combined with post ECAP aging treatment has been found to be more effective than preECAP peak-aging treatment in enhancing the strength of a 6061 Al alloy.

TL;DR: In this paper, the photoactivities of ultrafine TiO 2 nanoparticles in the anatase, rutile or mixed-phases were tested in the photocatalytic degradation of phenol.

TL;DR: In this paper, the role of metallurgical factors in laser deposition of alloys is discussed and the significant role played by the thermodynamic enthalpy of mixing in the deposition of alloy from elemental powder blends using LENSTM is discussed.

TL;DR: In this paper, the results of nanoindentation tests of bulk glassy Pd40Cu30Ni10P20 using a specially designed instrument with high time and spatial resolution are presented.

TL;DR: In this paper, the reverse transformation of a low carbon Fe −13%Cr −7%Ni −3%Si martensitic stainless steel occurs by diffusion, whereas it occurs in a diffusionless manner above 10°C/s.

TL;DR: In this article, the authors evaluated the influence of aluminium and silicon contents, in view of the development of multiphase TRIP-assisted steels, on the extent of the transformation induced plasticity (TRIP) effect.

TL;DR: In this paper, a new kinetics equation for DIMT has been formulated as f/fs=1−exp[−β(e−e0)n] with the parameter β characterizing the stability of retained austenite, n denoting a deformation mode, and fs the saturation value of transformed martensite volume fraction.

TL;DR: In this paper, the theoretical background and experimental results for ultra-fine aluminium powder production are described, where the process can be regarded as adiabatic and particle formation with designed characteristics would be possible.
