In this study, the effects of surface treatment namely electro-pulsing followed by laser shock peening (EP-LSP) on wear resistance properties Ti–6Al–4V alloy are investigated. It was compared with samples treated solely (LSP) and (EP) to investigate different processes friction alloy. addition, coefficient, rate, morphology were also Finally, mechanism described in detail. The results demonstrated a significant reduction grain size for after EP-1-LSP treatments. Furthermore, as-received...
To solve the problem of poor abrasion resistance concrete pavement surface mortar, this study substituted cement with equal amounts styrene–butadiene rubber (SBR) latex and silica fume (SF) to investigate effects organic/inorganic material composite modification on fluidity, drying shrinkage, mechanical properties, mortar. Also in study, microstructure, product, pore structure characteristics modified mortar were investigated using scanning electron microscope (SEM), X-Ray diffraction (XRD),...
The thread rolling process is an advanced bulk forming to produce parts. superior performance of the formed parts as compared those manufactured by cutting closely relates microstructure In this study, a finite element model (FEM) was established analyze deformation characteristics in process. viscoplastic self-consistent (VPSC) simulation coupled with FEM investigate texture evolution and distribution. Besides, experiments were carried out, on different positions observed verify simulation....
This study investigated the effects of light-burned magnesia, fly ash (FA), dolomite powder (DP), and limestone (LP) contents on performance magnesium oxychloride cement lean concrete (MOCLC). The magnesia mineral admixture content mechanical properties durability MOCLC were tested by compressive strength test, splitting water resistance shrinkage fatigue respectively. results revealed that optimum dosage MgO was 4%. dosages FA, DP, LP 25%, 20%, 20% dosage, strengths decreased addition FA...
In the forming process of long threads by axial self-infeed rolling process, protrusion generates on top tooth profile, which affects strength and precision formed threads. this article, principle was described, finite element model established to simulate The formation mechanism analyzed through material flow, verified experiments. pre-rolling angle material’s influence size also investigated. results showed that motion rollers squeezed one flank tooth, leading higher face side as compared...
An in-situ solid state repairing method for the failure flat clinched joint was proposed to reconstruct appearance and improve mechanical properties. The microstructure, properties, fracture behavior of repaired joints were comparatively investigated clarify feasibility effectiveness this method. Results indicate that fractured neck is successfully in-situ. microstructure weld nugget sufficiently refined, which enhances properties joint. Rotation speed dwell time play crucial roles on...
The axial self-infeed rolling process is an advanced and efficient to form long threads such as lead screw thread shaft. experiments of for the stainless steel were conducted with three blank diameters, forming speeds two lubrication conditions. effects speed, diameter condition on torque, microhardness tooth height analyzed by design experiment analysis variance. And characteristics distribution investigated. results revealed torque was more influenced speed than condition. sensitive all...
Abstract The rolling process is an important processing technology for improving the performances of thread shaft. In this paper, axial self-infeed investigated. principle introduced and formed shaft with copper T2 are evaluated. addition, major diameter torque during studied. hardness improved 74.2% microstructure fibrous tissue in bottom tooth groove. size blank has greater impact on forming than rotating speed blank.
A notch-induced high-speed precise shearing method was developed for high-strength metal bars, which prefabricated V-shape circumferential notches in batch on the bar surface to make stress concentration, and applied a load complete separation new type of electric-pneumatic counter hammer. The FE simulation experimental tests were conducted; influences loading speed, notch depth, axial clearance analyzed fracture behavior blank quality; microfracture mechanism further investigated. results...
