The study investigated the microstructure and mechanical properties of composite strengthened high-chromium cast iron by laser quenching shock peening. Observation microstructure, measurement microhardness, residual stress FWHM (full width at half maximum), impact toughness wear tests were carried out on untreated, quenched, quench-laser peened specimens. research results showed that peening will not produce new phases in iron, can further promote transformation retained austenite into...
In this paper, quench-tempering (QT) and laser quenching (LQ) treatments were performed on the high-chromium cast iron to obtain better microstructure mechanical properties. The changes in microhardness, microstructure, retained austenite (RA) content, grain size, phase elemental content of QT LQ samples compared analyzed. results showed that RA untreated was 77.02% 26.8 nm. an increase carbide dissolution, gradual rounding from sharp angles, transformation into martensite, reduction 28.48%,...
In order to achieve high-performance coatings on the surface of electric submersible pump impellers, it is crucial optimize laser cladding process parameters. Using Ansys 2021 R1 commercial software, a numerical simulation Ni60 powder high nickel cast iron was conducted. The utilized 3D Gaussian heat source, parametric language, and life–death unit technology replicate characteristics synchronous delivery cladding. study focused analyzing temperature field cloud map molten pool size under...
With the rapid development of new-generation information technologies such as big data, cloud computing, Internet Things, and mobile internet in traditional manufacturing, intelligent manufacturing (IM) is accelerating. Digital twin an important method to achieve goal IM, provides effective means for integrated design (R & M). In view problems long installation debugging cycles, process parameters requiring multiple trial error research D) laser melting deposition (LMD) equipment, this...
In this study, an Inconel625-Ni60-Ni60/25%WC (Inconel625-Ni/WC) composite coating was fabricated on Cr12MoV steel by first-stage laser cladding, followed second-stage remelting with various powers, and the better energy density of 25.0 J/mm2 for test obtained macroscopic morphology microhardness analysis. The effects microstructure, microhardness, wear resistance, impact resistance systematically investigated combining characterization methods. results showed that did not cause to produce...
Laser shock peening is a promising surface strengthening technology that can effectively improve the mechanical properties of materials. This paper based on laser process for HC420LA low-alloy high-strength steel weldments. Contrast analysis evolution microstructure, residual stress distribution and welded joints before after each region carried out; combination tensile fracture impact toughness morphology analyses joint strength regulation mechanism are also completed. The results show...
