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,...
Job shop scheduling problem (JSSP) is a typical NP-hard problem. In order to improve the solving efficiency for JSSP, hybrid differential evolution and estimation of distribution algorithm based on neighbourhood search proposed in this paper, which combines merits Estimation Differential (DE). Meanwhile, strengthen searching ability algorithm, chaotic strategy introduced update parameters DE. Two mutation operators are adopted. A (NS) blocks critical path used further solution quality....
In this article, an improved multi-objective evolutionary algorithm, which is based on decomposition (IMOEA/D) for job shop scheduling problem, proposed to solve multiple objectives problems. Three minimisation – the maximum completion time (makespan), total flow and tardiness are considered simultaneously. several prior rules presented construct initial population with a high level of quality. Meanwhile, according contribution each operator external archive, adaptive mechanism adopted...
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...
Very limited comparative research has been conducted on microstructure evolution induced by different peening methods. Herein, the 2024T351 aluminium alloy was subjected to conventional shot (CSP) and ultrasonic (USP) under identical Almen height investigate differences in surface roughness, residual stress microhardness. The results demonstrated that same height, CSP treatment resulted a rougher with higher roughness more defects, maximum compressive (CRS) than USP treatment. In contrast,...
