Starting materials used were 99.8% pure nickel, 99.9% pure iron, 99.9% pure tantalum, and 99.9% pure molybdenum. The materials in a total weight of 500g were melted with a high-frequency induction furnace in vacuum. The melt was poured into an iron mold with an opening of 20mm diameter and 150mm length. After forging, the ingot was reduced to a thin plate 0.3mm in thickness by rolling and a wir...

Abstract Rolling speed ratios during the rolling process are critical to ring forming in this pepper. The selected roll feed mode is constant with increasing of diameter main stage. Based on Deform-3D finite element software, a large size φ1530 mm was taken as research object. numerical model 40Cr13 stainless steel established. radial-axial rings under different increase speeds simulated, and c...

The paper presents the results of theoretical research scientific works on determining durability fixed rolling bearing joints with restored anaerobic sealants, develops a scheme angular mixing outer ring at deformation adhesive layer, and derives analytical dependence absolute elongation layer in operating conditions.

Molecular dynamics simulation of a five-site model of methane within zeolite NaCaA and ab initio calculations have been reported. Methane shows a preferential orientation during its passage through the eight-ring window. Partial freezing of certain rotational degrees of freedom is observed during the passage of methane through the eight-ring window, which acts as a bottleneck for diffusion of m...
