In order to apply laser cladding technology the complex surface processing of hot-working dies, this study developed a numerical model for curved along various scanning trajectories under multi-physics coupling considering dynamics molten pool, parameters (scanning speed and power), Marangoni effect, solid–liquid phase transition. Utilizing by altering parameters, temperature field variation in coating thickness were studied as well interaction between two. The following discoveries made....
A novel ultrasonic vibration assisted (UVA) wire arc additive manufacturing (WAAM) was used to fabricate Cu-8Al-2Ni-2Fe-2Mn alloy in this study. The effect of different interpass temperatures with and without on the microstructural evolution mechanical properties fabricated part were investigated by optical microscope (OM), scanning electron (SEM), transmission (TEM), nanoindentation, tensile testing. results showed that reduction temperature UVA treatment cannot prevent columnar dendrites...
High-temperature oxidation and corrosion behavior of Ti6Al4V alloy at 650 °C for 1000 h were investigated using a salt mixture (25 w/% NaCl 75 Na2SO4) as the thermal medium. The mass increase due to alloy’s analyzed quantitatively. surface morphology cross-sectional structure after scrutinized via X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS). Results show that exhibits certain antioxidant property in high-temperature environment °C, but...
Numerous efforts have been made to promote the efficiency of protein delivery through tuning surface properties such as grafting polymers on surface, but limited successes achieved, and their great clinical expectation has not yet realized. The main reason is that proteins are readily recognized foreign materials under physiological conditions due genetic distance between species, leading rapid decrease in activity clearance by mononuclear phagocyte system. In this study, we encapsulated...
2Cr13 thin-wall part was additively deposited by robotic cold metal transfer (CMT) technology, and two traditionally manufactured counterparts in annealing (as-Aed) quenching & tempering (as-QTed) conditions were adopted as comparison. The results show that only a strong texturing corresponding to α-Fe phase detected for the wire-arc (WAAM) part, indicating an austenite-free structure. As-deposited microstructure consisted of martensite laths ferrite matrix, along with irregular δ-ferrite...
Reduced activation ferritic/martensitic (RAFM) steel is an iron-based alloy as a candidate structural material in fusion reactor. This paper evaluates the compatibility of RAFM choice for wire arc additive manufacturing (WAAM). Two specimens steels with high and low heat input were fabricated by WAAM. The effects on microstructure, microhardness tensile properties samples investigated. boundaries are spaced uniformly whole sample. Three distinctive zones present periodic region, including...
The heterogeneous microstructure and mechanical properties of the strut tensile sample were investigated in this paper. A novel Inconel 718 was designed fabricated based on selective laser melting (SLM). standard samples horizontally vertically comparing with samples. results exhibit that mean elasticity modulus nanohardness eutectic-free area, which are 167 GPa 5.89 GPa, respectively, is higher more homogeneous than other three areas. Mechanical determined a bond tester, elastic modulus(E),...
Plasma arc additive manufacturing (PAAM) was applied to fabricate TC4 and Ti48Al (gamma titanium aluminide) bimetals in this work. The impact of deposition sequence on the microstructure mechanical properties two groups (TC4-Ti48Al, first deposited TC4, then Ti48Al; Ti48Al-TC4, Ti48Al, TC4) investigated. results show that ultimate tensile strengths exhibit significant differences, with 158.4 MPa for TC4-Ti48Al 232.3 reason disparity is difference at transition zone, which attributed heat...
