The ultrasonic shot peening (USP) treatment was adopted to improve the compressive residual stress, microhardness and corrosion resistance of Ti–6Al–4V (TC4) titanium alloy fabricated by selective laser melting (SLM). optical microscope (OM), scanning electron (SEM), X-ray diffraction (XRD) hardness test were used investigate microstructure evolution. effect USP on electrochemical behaviour SLM TC4 in a 3.5 wt. % NaCl solution studied using potentiodynamic polarization. After treatment,...
High entropy amorphous alloys (HEAAs) are materials that have received much attention in recent years. They exhibit many unique properties; however, research on their composition design method has not been deep enough. In this paper, we summarized some effective strategies for HEAAs. By adjusting the atomic ratio from quinary bulk metallic glasses, Ti20Zr20Cu20Ni20Be20 HEAA with a high fracture strength of 2315 MPa was designed. similar element addition/substitution, series Ti–(Zr, Hf,...
The low-cost Fe-based amorphous coating with the composition of Fe49.9Mo32.9Cr9.32Co4.55Si2.28Al1.55 (wt.%) were deposited on 316L stainless steel substrate by subsonic flame spraying under optimum parameters. microstructure, phase composition, microhardness, corrosion-resistance, and wear-resistance properties coatings systematically investigated. prepared primarily consists (calculated content was 90.23%), hardness can reach 981.6 HV0.1, which is much larger than that material steel....
Post-heat treatment and in-situ rolling, both can be used to improve the coarse grains anisotropy that are prevalent in metallic materials, fabricated by wire arc additive manufacturing (WAAM). In this study, effect of rolling heat on microstructure, mechanical corrosion behaviors WAAM 316L was investigated. The results showed microstructure changed considerably due introduction deformation, as it observed ferrite distributed a reticulated or equiaxed morphology instead dendritic...
Additive and subtractive hybrid manufacturing (ASHM) technology has attracted extensive attention in industry academia because of its vast design freedom surface accuracy. The powder bed fusion (PBF) process high forming accuracy, the ASHM PBF is more suitable for integrated precision components with complex internal structures. However, existing planning are not limitation by bed. This research work focused on process, while dividing it into three stages. Firstly, a model adaptive...
Two series of high-carbon pearlitic steels (68C-xNb and 75C-xNb) with different C Nb contents were produced by hot-rolling. The effects on the microstructure impact toughness investigated using scanning electron microscope, transmission backscattering diffraction tests. In particular, nucleation growth pearlite through in-situ observations. It was found that average nodule markedly refined from 10.2 μm to 6.0 addition 0.026 wt.% in 68C steels, it 13.7 6.7 0.014 75C steels. situ observations...
Abstract Titanium alloys fabricated by selective laser melting (SLM) are typically subjected to post-treatments, such as shot peening, improve the mechanical properties. However, same Almen intensity may correspond various combinations of peening parameters, which will generate different microstructures and comprehensive Herein, SLMed Ti64 alloy was treated pneumatic (SP) ultrasonic (USP) under 0.2 mmA, investigating changes microstructure corrosion resistance. The average surface roughness...
