The amorphous alloys Ti 6 7 Si 3 3 , V 6 7Si 3 3 , and Cr , 7 Si 3 3 were produced by sputtering. Their structure was investigated by X-ray and neutron diffraction. X-ray diffraction showed that the structure of the three metallic glasses is not isomorphous. Neutron diffraction showed that S i -S i atomic pairs occur preferentially with distances distinctly larger than the atomic diameter of th...

In the past two decades, coatings of the Ti–Al–N ternary system have attracted considerable research and industrial interest. Nevertheless, the Ti–Al–N system still offers new interesting possibilities for coating developments such as the addition of low N contents to Ti–Al films in order to reach a good compromise between high hardness and a low friction coefficient. Ti–Al–N coatings with low ...

Surface microstructures were investigated in pure iron and Fe-1mass%M (M = Mn, Cr, Al, Si) alloys gaseous-nitrided at 1123 K quenching to reveal the alloying effects on surface hardening by nitrogen (N) martensite. Thicker hardened layers with higher hardness than obtained Mn-added whereas additions of Si Al lead increase reduction layer thickness. On other hand, adding Cr decreases both thickn...

The title compound, [Ti(C(15)H(23)N(2)Si)Cl(3)]·0.5C(4)H(8)O, has been prepared from {2-[2-(η(5)-cyclo-penta-dien-yl)-2-methyl-prop-yl]-1H-imidazolyl-κN(1)}bis-(N,N-diethyl-amido-κN)titanium(IV), (C(12)H(14)N(2))Ti(NEt(2))(2), by reaction with excess of Me(3)SiCl in tetra-hydro-furan (THF) at 353 K. The crystal structure contains THF as adduct solvent, disordered around a center of inversion. T...

In the title compound, [Ti(C(8)H(13)Si)(C(11)H(21)Si(2))Cl(2)], the Ti(IV) atom is bonded to two Cl atoms, one 1,3-bis-(trimethyl-sil-yl)cyclo-penta-dienyl (Si(2)Cp) and one (trimethyl-sil-yl)cyclo-penta-dienyl ring (SiCp). The Si(2)Cp centroid-titanium distance is 2.0763 (10) Å and the SiCp centroid-titanium distance is 2.0793 (10) Å. The angle subtended at the Ti atom by the centroids of both...

Al assisted alloying of carbon steel in Submerged Arc Welding (SAW) by Al-Cr-Ti-Cu unconstrained metal powders is applied. A base case without powder additions compared to two addition schedules, Al-Cu-Ti and Al-Cu-Ti-Cr. used as a deoxidiser element control the oxygen partial pressure at weld pool–molten flux interface ensure that most Ti Cr transferred into pool ppm O controlled within accept...
