Stainless steel welding has been widely used in industrial manufacturing, and friction stir recognized to reduce production costs significantly. To fully utilize the different properties of 2507 super duplex stainless (SDSS) 317L austenitic (ASS), mechanical surface SDSS ASS dissimilar joints were improved using (FSW) method. The influence rotation speed on microstructural characteristics, properties, corrosion behavior weld was investigated by at a constant 20 mm/min within range 300–600...
SiCp/6061Al composites have been developed and widely applied in many fields, such as automobile, aerospace, shipping, so on. Considering heat treatment, service environment, strength of composites, this paper comprehensively studies the mechanical properties with a large range SiC mass fractions under T6 treatments different tensile temperatures. were successfully prepared by hot press sintering at various (0–30%), influences concentration treatment on characterized via tests room...
In the present study, 1.86‐mm‐thick steel plates (UNS S32205) were friction‐stir‐welded at various rotation speeds of 300 to 600 rpm and a constant welding speed 100 mm·min −1 . The effect on microstructure mechanical properties welds was researched. temperature recorded during friction stir (FSW), assessed. incomplete penetration defect formed due insufficient heat input, macroscopic groove‐like because serious sticking tool. Defect‐free obtained 350 500 rpm. lower corresponds input FSW,...
Abstract Allylic C(sp 3)–H functionalized architectures are not only widely present in natural products, pharmaceuticals, and functional organic materials, but also serve as versatile building blocks to furnish important molecules synthetic chemistry. Accordingly, various strategies access allylic alkenes a stereoselective manner have been developed. However, chemo-, regio- intermolecular asymmetric functionalization (AAF) of unreactive acyclic alkene (UAA) from readily available...
Motivation: Patients with high-risk non-disabling ischemic cerebrovascular events (HR-NICE) are recommended as the key population for stroke prevention. However, functional impairment and underlying neural mechanisms rarely investigated in this cohort. Goal(s): We attempt to confirm cognitive explain mechanism of aspects both hypoperfusion cortical abnormality HR-NICE patients. Approach: Cerebral blood flow, grey matter volume asymmetry were calculated based on MR perfusion anatomical data....
Dissimilar friction stir welding (FSW) of 2205 duplex stainless steel (2205 DSS) and 304 austenitic (304 ASS) is carried out with various parameters. The effect material position tool offset on flow mixing, the microstructure, mechanical properties joints are investigated, relationship between torque determined. With to retreating side (RS), defect‐free proper mixing fabricated. When ASS placed advancing (AS), better than case opposite position, but results in a larger stirring zone (SZ)...
Electropulsing treatment (EPT) is a potential annealing method with advantages of performance improvement and equipment simplification. In the current paper, effect EPT on recovery AZ31B magnesium alloy during two-stage plastic deformation process was studied. The tensile properties, residual stress, microstructure, kinetics were evaluated. stress decreased cumulative elongation increased slightly, whereas yield strength retained relatively high after EPT. A typical observed. Moreover,...
Supercritical carbon dioxide cleaning technology has many advantages over the traditional process, so it is necessary to study effect of supercritical flow on adhering particles microchannel surface. In this paper, magnitude adhesion force between and substrate was analysed theoretically according different nature microfine particles, action during in slip zone studied by COMSOL Multiphysics software with individual metal inner wall surface microchannel. Research shows that as temperature...
