To investigate the influence of steel composition on the formation of these surface coatings, friction, fatigue, and static immersion studies were conducted with two case-hardened steels (1018 and 4118) and five through-hardened materials (51100, 52100, M-50, 440-C, and Stellite #3). More ...
100% steel 0.017% N Oxygen absorption in cast irons The absorption of oxygen during the melting of different types of iron under various conditions has been measured and related to the equilibrium oxygen concentrations predicted from C, Si and Al deoxidation reactions80,82 and to graphite nucleatio...
The relationship between the surface composition and electrical properties of corrosion films formed on carbon steel in alkaline sour medium: An XPS and EI... This work studies the evolution of 1018 carbon steel surfaces during 3-15 day immersion in alkaline sour medium 0.1 M (NH4)(2)S and ...
Molecular dynamics is applied to explore the deformation mechanism and crystal structure development of the AlCoCrFeNi high-entropy alloys under nanoimprinting. The influences of crystal structure, alloy composition, grain size, and twin boundary distance on the mechanical properties are carefully analyzed...
For example the plate materials may be steel, paper, ceramic, carbon fibers and systems employing a mixture of plate types such as steel on ceramic, carbon fibers in paper or steel on paper. In one embodiment, the invention provides a lubricating composition comprising (a) at least 0.05 wt ...
The adhesion advantage is even greater when the test panels of the mold are made of carbon steel, e.g. 1018 steel. The peel strength of the TFE/PEVE copolymer-containing lining is 96.2 lb/in (16.8 kN/m). The peel strength of the TFE/PPVE copolymer-containing lining is 44.3 lb/in (...
The EO of organically cultivated T. capitatus plants (Aegean Organics, Agios Dimitrios, Lemnos, Greece) was distilled in a 110 L stainless steel (18/10) distiller. A perforated basket containing 5 kg (dry weight) of the top cuttings of thyme (stems, leaves, and flowers) was loaded in the...
cross-sections of the apical part of the implants to be analyzed were made with a micro-cutting machine. Samples of each implant of a 4 to 6 mm thickness were obtained. Each was analyzed by a tactile profilometer and scanning electron microscope (SEM). Compositional measurements were performed...
