Grain structure control is challenging for metal additive manufacturing (AM). optimization requires the of grain morphology with size refinement, which can improve mechanical properties manufactured components. This work summarizes methods to promote fine equiaxed grains in both process and subsequent heat treatment. Influences temperature gradient, solidification velocity alloy composition on are discussed. Equiaxed greatly promoted by introducing a high density heterogeneous nucleation...
Titanium nitride (TiN) films can be utilized as hard and protective coatings for synchronizer ring, which is the key components of car gearbox. The tribological properties ring play a role in safety reliability shifting system. aim present work to improve investigate effects depositing gas on preferred orientation, surface morphology, roughness TiN thin films. as-prepared are deposited copper alloy (TL084) Si (100) substrates by closed field unbalanced magnetron sputtering different with...
Motivated by the observation of in-situ nanocrystallization in surface layer plasma nitrided steels, this work is carried out to establish a thermodynamic model that describes Gibbs free energy BCC-Fe solution using quasi-binary model. The specifically developed for nitriding process multi-component whose composition first converted an Fe-Creq-N ternary system concept Cr equivalent through relative elemental electronegativities with respect nitrogen. With model, limit stability BCC pseudo...
Distribution of characteristic times (DCT) is proposed to resolve chemical relaxation in porous MIECs and estimate kinetic parameters.
Predicting the mechanical properties of additively manufactured parts is often a tedious process, requiring integration multiple stand-alone and expensive simulations. Furthermore, as are highly location-dep... | Find, read cite all research you need on Tech Science Press
AZ91D magnesium alloy coated with magnetron sputtered alternating Al/Ti multilayer was plasma nitrided at different temperatures, and the changes of its microstructure corrosion properties were investigated. Compared pre-coated specimen, it shown that microhardness resistance after nitriding treatment are improved significantly. In addition, surface hardness promoted to more than twice substrate, potential shows a significant positive shift. The improvement in is attributed solid solution...
Diamond-like films (DLC) are an exceptional engineering material with excellent performance such as high hardness, low friction coefficient, superior wear resistance and chemical inertness. However, two major problems of internal stress poor thermal stability have seriously limited its industrial applications. In particular, the microstructures properties pure DLC highly sensitive to temperature. Therefore, purpose this study is investigate effect annealing temperature on as-prepared films....

The increasing demand for advanced materials with load-bearing capabilities in extremely high-temperature environments has brought considerable attention to the design and fabrication of novel refractory complex concentrated alloys. Despite notable progress customized alloys, there are still significant challenges regarding their processing fabrication, highly limiting exploitation. In this study, model non-equiatomic Nb-Ta based alloys were created as potential improved stability...
Diamond-like carbon (DLC) has excellent performance but cannot be directly applied in gears and bearings due to poor adhesion. A novel gradient composite layer that includes a hardened nitrided self-lubricating DLC structure at the outermost surface was fabricated on M50 steel via plasma-assisted thermochemical treatment. The evolution of modified comprehensively characterized by optical microscopy, scanning electron microscope (SEM), atomic force microscopy (AFM), transmission (TEM), Raman...
