“…In terms of contact type, hard contact is used in the normal direction and no penetration behavior between contact pairs is allowed. Since it is a rolling problem, the tangential contact is calculated using the frictional contact mode of the penalty function method with the friction coefficient set to 0.1 [9] . The rolls and mandrels are set as rigid bodies, the billet is set as elastic-plastic, and the mandrels are fixed during the rolling process, in which the roll speed loading amplitude curve is approximated to be applied as a sinusoidal curve.…”

Taking the rolling of 5B02 aluminum alloy tubes in Pilger LG50 mill as an example, the finite element analysis of the tube rolling process was carried out by using ABAQUS software. The effects of rolling speed, rotary angle and feeding amount on the inner wall stress of the tubing and the dimensional accuracy and ellipticity of the finishing section in the forming process of Pilger rolling of 5B02 aluminum alloy tubes were investigated through the orthogonal test. The optimal process parameters were preferably selected for the experimental validation. The results show that the stresses in the inner wall of the wall-reduced section of the billet are the highest during the whole rolling process. The average stresses in the inner wall of the reduced wall section of the billet are in the following order: feed>rotary angle>rolling speed. The feed and rolling speed have a greater influence on the dimensional accuracy and ovality of the finishing section. Excessive rotary angle can lead to grid distortion in the reduced-wall section of the billet. The 5B02 aluminum alloy tubes rolled at a rolling speed of 1989mm/s, a rotary angle of 57°, and a feed of 2.5mm meet the requirements of dimensional accuracy, internal surface quality, and metallurgical structure, and improve production efficiency.

“…As shown in fig. 6, rolling piece rolled into pass 1 in the 0.1s,and points of A and E have contacted with the guide before rolling into the pass 1, so stress of A and E is higher than other points of B, C, D. Secondly, the maximum stress is 345MPa in 4-pass rolling process, less than yield limit of rolling piece, so rolling piece does not appear defects inside, internal quality is improved [5].…”

According to a company’s trapezoidal stainless steel sieve bar specification, 4-stands pass system and rolling program are proposed. To verify the pass system, 4-stands sieve bar three-dimensional finite element model is established and simulated by ANSYS/LS-DYNA. Parameters, such as metal flow law (metal longitudinal flow, metal lateral flow) and power parameters (stress, strain and rolling force), are obtained, and provide a reference for new product pass design optimization and improvement.

“…Titanium and titanium alloy material are widely used as artificial joint, artificial bone, dental implants in the field of medical implants by right of its high strength, good biocompatibility, good corrosion resistance and other properties. But problems such as release of metal ions, low bonding strength with host bone, low hardness and dissatisfactory abrasion resistance also exist, which limits its widely clinical use [1][2][3]. In recent years, numerous researchers have done surface modification with the method of chemical treatment, sol-gel, ion implantation, anodic oxidation [4][5][6][7] and etc to meet the needs of clinical application.…”

The porous oxide TiO2 ceramic film containing Ca and P is fabricated on the surface of pure titanium in the electrolyte of C4H6CaO4-NaH2PO4 by micro-arc oxidation (MAO) method. The microscopic structure, elemental composition and phase components of Ceramic Film are studied with scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), 3D profilometer and etc. Results indicate that the ceramic film on pure titanium by micro-arc oxidation is a porous mixed crystal structure which contains anatase TiO2 and rutile TiO2, and that the film is mainly composed of such elements as Ti, O, Ca and P. With frequency increasing, the number of micropores increases, the hole is decreased in diameter, porosity and roughness,and the surface is more smooth. The increase of frequencies makes the ratio of Ca/P decrease, the relative content of anatase TiO2 increase and rutile TiO2 decrease.
