Laser remelting is a promising in-operando method to improve surface quality and eliminate defects simultaneously in the laser-powder bed fusion process. In this study, optimal processing parameters for laser influences of on porosity, microcracks, roughness, microhardness mechanical properties AISI 4140 steel manufactured by were investigated. The results showed that improved relative density 99.6% microstructure changed from lack keyhole morphology as number steps increased. roughness...
Abstract To study the manufacturability and mechanical properties of a low alloy heat treatable medium carbon steel by additive manufacturing, 42CrMo4 (AISI4140) specimens were manufactured laser powder bed fusion. Influences processing parameters on relative density crack investigated. Moreover, Charpy impact tests, microhardness, tensile tests for with without preheating also studied. Results showed that primary defects in microstructure additively samples lack fusion pores microcracks....
AISI 630 alloy is widely used in the manufacture of CFM56 series aeroengine fan casing because its high strength and excellent ductility. Herein, directly manufactured by directed energy deposition. The microstructural evolution, mechanical properties, fracture behavior as‐deposition, solution, aging conditions are analyzed. Scanning electron microscopy, X‐ray diffraction, backscattering diffraction to characterize microstructure phase characteristics. Mechanical tensile Vickers hardness...
Flexible bending successfully solves the problem of multi-curvature and small batch tubes. In flexible process tubes, stress state deformation bent tubes are complex. order to better understand analyze was analyzed mechanically formula moment deduced. The residual in forming by finite element numerical simulation. results show that is closely related tube specifications, material properties curvature. bending, distribution circumferential has some regularity; thrust pusher stability...
