The as-welded low-transformation-temperature (LTT) weld metal with martensite/retained austenite (RA) dual phase exhibits high toughness and ductility, but the yield strength (YS) is very low. After low-temperature postweld heat treatment at 300°C, YS, ductility of dual-phase LTT increase dramatically, while there a slight effect on mechanical properties full martensite metal. During treatment, carbon atoms diffuse from into RA, which increases stability RA. improvements for after are...

Air-staged combustion of blended coals is now a common choice for coal-fired boilers in China as primary method to control NOx emission. Reductive gases, CO and H2, corrosive H2S COS, are generated the fuel-rich zone which leads problems high temperature corrosion, slagging fouling under reducing atmosphere. This study focuses on generation properties reductive gases during air-staged combustion. Experiments anthracite, sub-bituminous, their blends with different mixing ratios were conducted...

The composite bucket foundation (CBF) is a cost-competitive for offshore wind turbines, which can be adapted to the loading characteristics and development needs of farms due its special structural form. There are seven sections divided inside CBF by steel bulkheads, arranged in honeycomb structure. six peripheral with skirt have same proportions while middle orthohexagonal one little larger. With seven-section structure, has reasonable motion towing reliability during wet-tow construction...

Rubber sleeve is sealing component of underground packers, the rubber will occur corrosion or failure under acid medium environment, which causes gas leak and leads to security problems wellbore. In paper, testing was carried out AFLAS using HTHP autoclave in harsh environment with pressure 60 MPa, temperature 175°C, test period 7 days compositions phase are 20vol% H2S, 5vol% CO2, 75vol% CH4. Comparing analyzing changes properties liquid before after testing, such as quality, volume, tensile...

Two types of low-transformation-temperature weld metals were devised, one associated with primary austenite solidification, the other ferrite solidification. The martensite start temperature both was about 125°C. Experimental results showed that microstructure solidification 8.0% retained austenite, whereas related to primarily consisted and δ-ferrite. Accordingly, welded joints had little distinction between distortion residual stress, indicating metal played same function as on stress...

The microstructural variations of the Nd60Al10Fe20Co10 melt-spun ribbons and as-cast rod were studied by high resolution transmission electron microscopy (HRTEM), x-ray diffraction (XRD) differential scanning calorimetry. Nano-clusters in glassy matrix both ribbon samples observed HRTEM, though no obvious crystalline reflections displayed either XRD or selected area patterns. magnetic properties sample compared to that ribbons. It was found coercivity alloy increases with size nano-scaled...

An ultrasonic pulse–echo method was used to measure the transit time of longitudinal and transverse (10 MHz) elastic waves in a Nd60Al10Fe20Co10 bulk metallic glass (BMG). The measurements were carried out under hydrostatic pressure up 0.5 GPa at room temperature. On basis experimental data for sound velocities density, moduli Debye temperature BMG derived as function pressure.

The initial filling period during ingot casting was studied theoretically. motivation that it is crucial to achieve a preferred flow pattern which can lead smooth condition, particularly the teeming stage. In this study, twist-tape swirl blade applied in mathematical model create inlet of mold. set vertically just beneath inlet, made gradually divergent cross section area. results showed combinations and mold with bottom contributes to: i) Inlet passes along wall mold, ii) formation very...

We study the heat transport in a graphene-based normal-superconducting junction by solving Bogoliubov-de Gennes (BdG) equation. There are two effects, competitive and cooperative which come from interaction between temperature-dependent energy-gap function superconducting region occupation difference of quasiparticles. It is found that effect can not only bring negative differential thermal conductance but also rectification effect. By contrast, just causes Furthermore, ratio magnitude...

After pneumatic shot peening, compressive residual stress is induced on the surface of target, which will improve fatigue life. During process, roughness also induced, may reduce To achieve optimum with smallest roughness, formation mechanism field and topography are revealed. Then, peening simulated by using a discrete element method–finite method coupled model. Based effects four variables (the incident angle θ, initial velocity v 0 , radius R) mass flow rate r m five parameters equivalent...

The solidification behaviour and microstructure of welding transition zone between low-transformation-temperature deposited metals high-strength low-alloy steels were investigated. It was found that the steep composition gradient provided driving forces for diffusion carbon from base metal to weld metal, leading hardened softened regions near fusion boundary. In boundary, there retained δ-ferrites when dilution rate below 35% Cr eq /Ni value larger than 2.62. Compared with martensite, mixed...
