In this paper, nano-Ti-2Fe-0.1B alloys with different grain sizes were processed by high pressure torsion (HPT) deformation. The study examined the microstructural evolution of Ti-2Fe-0.1B alloy during HPT and evaluated its mechanical properties through microhardness tensile tests. results observations revealed that size progressively decreased from 3.14 μm in as-annealed state to approximately 20nm after 10 turns. initial state, consists -phase -phases, a volume ratio 5:1. During process,...
Selective laser melting (SLM) is an advanced additive manufacturing technique that can produce complex and accurate metal samples. Since the process performs local high heat input during a very short interaction time, physical parameters in solidification are difficult to measure experimentally. In this work, microstructure evolution of Ti-6Al-4V alloy was studied. With increase scanning speed, cooling rate temperature gradient molten pool position increased, which attributed gradual...
Selective laser melting was recently introduced to fabricate complex parts that are likely contain overhangs. Process parameters, scanning strategies, support structures, and fast prediction techniques being frequently studied, but little information about overhang forming direction has been reported. In this study, the effects of in working plane on temperature evolution distortion processes during selective Ti-6Al-4V alloy were examined by means numerical simulation experimental...
In this work, the newly developed Ti-35421 (Ti-3Al-5Mo-4Cr-2Zr-1Fe wt.%) alloy was prepared by laser deposition manufacturing because it contains several main elements that could refine grains, which is expected to achieve transformation from columnar equiaxed grains. The results show microstructure mainly composed of grains and includes grain boundary α, lath α acicular α', leading high tensile strength (1446±46 MPa) low elongation after fracture (1.7±0.3 %). After solution aging treatment,...
In this paper, the effects of process parameters and design on mechanical properties 316L diamond lattices manufactured by laser powder bed fusion were investigated basis real relative density. The lattice structures different hatch spacing analyzed under uniaxial compressive loading for proving that should be from bulk materials. with densities, cell sizes, strut diameters contour sizes to study joint parameters. It can found could affect actual density, obtaining density is key correctly...
