3D printing brings new opportunities for the development of civil engineering. Machine learning (ML) is also widely used in various fields printing. To describe main research issues and potential future applications ML construction printing, it essential to comprehensively overview current topics. This paper aims review, summarize, analyze, introduce progress followed by a discussion challenges scope. Firstly, classification working principle technology were introduced. Secondly, aspects...
51CrV4 steel is extensively used in large-size damping springs for trains and vehicles. Quenching conditions play an important role performance enhancement. The present work investigated the effects of various oil-bath temperatures out-of-oil on microstructure mechanical properties this steel. morphological examination focused both quenched martensite tempered troostite. Tensile hardness tests were carried out to evaluate properties. results showed that a coarsening occurred at high...
This study investigated the evolution of microstructure and mechanical properties 60Si2CrVNb spring steel under different quenching tempering processes. The morphology martensite, precipitate phases, carbides, as well analysis properties, were examined. results revealed that highest ultimate tensile strength (2260 MPa) yield (2091 achieved through austenitization at 900 °C subsequent 350 °C, which is related to maximum dislocation strengthening effect. optimal combination for was obtained by...
In this study, a series of austempering treatments were carried out on the designed novel 60Si2CrVNb spring steel and effects different temperatures microstructure mechanical properties studied. The results show that after treatments, exhibited multiphase composed martensite, bainite retained austenite (RA). As temperature increased, proportion martensite gradually decreased, while significantly RA first increased then slightly decreased. carbon content stability increased. toughness...
This study systematically investigates the effect of small Cr addition on microstructure evolution, precipitation kinetics, mechanical properties, and electrical properties Cu-Ag alloy. Cu-6%Ag-(0.4%Cr) was selected as object to study. The alloys were cast by melting in a vacuum induction furnace, followed solution heat treatment aging at different temperatures times. results show that adding alloy can significantly enhance its while only slightly reducing conductivity. activation energy...
A series of problems, such as disordered development urban production and living space, low land use efficiency, ecological environment pollution, appear in the rapid industrialization urbanization process to seriously hinder sustainable human social economy environment. In this case, scientifically planning national space coordinating spatial function become key problems construction sustainably developing civilization under background new-style new rural development. The establishment...
We fabricated the Fe-18Cr-2Ni-1Mo-0.2C-0.2Mn-0.1Si heat-resistant steels containing 3 to 12% Co by casting in presence of a rotary electromagnetic stirring (EMS). The effect EMS on Fe–Cr–Co was evaluated size and type inclusions examination mechanical properties. morphology composition were observed, formation mechanism analyzed through thermodynamic calculation using Thermo-Calc. results showed that there mainly two types generated solidification process, including Al2O3 corundum MnO. Cr2O3...
Purpose Precise vehicle localization is a basic and critical technique for various intelligent transportation system (ITS) applications. It also needs to adapt the complex road environments in real-time. The global positioning strap-down inertial navigation are two common techniques field of localization. However, accuracy, reliability real-time performance these can not satisfy requirement some ITS applications such as collision avoiding, vision enhancement automatic parking. Aiming at...
Vibration contributes large increases in railway passenger discomfort during long-term sitting. Discomfort caused by vibration may differ different operation conditions. This paper conducted field measurements to investigate the interrelationships between three. Participants completed a 240-min train journey with their whole-body vibration, subjective comfort ratings and operating parameters being recorded. A correlation was observed estimated dose value comfort. The relationship that...

Abstract BACKGROUND CONTEXT : For patients with multilevel degenerative cervical myelopathy, laminectomy and posterior fusions (PCFs) instrumentation are widely accepted technique for symptom relief. However, hardware failure is not rare which results in neck pain or even permanent neurological leision. The prevalence of hardware-related complications lack in-depth study. PURPOSE To investigate risk factors after myelopathy. STYDU DESIGN: single-center, retrospective METHODS Fifty-six who...
The evolution of microstructure and mechanical properties 60Si2CrVNb spring steel under different quenching tempering process were investigated. By observing the morphology martensite, precipitate phase carbides, also test analysis properties. results showed that a maximum ultimate tensile strength (2260 MPa) yield (2091 achieved when was austenitized at 900 °C tempered 350 which corresponding to dislocation strengthening . optimal combination obtained heat-treated by for 30min 400 90min,...
