4043 AlSi alloy samples are fabricated by laser-arc hybrid additive manufacturing and wire arc manufacturing. To investigate the influence of laser energy on sample, microstructure evaluation mechanical properties studied. After input energy, there zones with finer grains reduced Si segregation. As a result, phases at grain boundaries in zone smaller than that other zones. And it is found semi-coherent interface between Al crystal orientation relations, [110]Al∥[110]Si (111)Al∥(220)Si,...
Laser welding is widely used in titanium alloy due to its high energy density, small heat affected zone, and rapid processing ability. However, problems with laser welding, such as deformation cracking caused by residual stress, need be resolved. In this paper, the stress of TC4 was studied using an ultrasonic laser. The plates considered a plane state. A pre-stress loading method proposed acoustoelastic coefficients are obtained. Based on known coefficients, transverse longitudinal stresses...
Lattice structures become the focus for scholars to research due its unique lightweight, high impact resistance and ideal noise reduction. Selective laser melting has a very effective convenient method preparing lattice of excellent quality. However, it is imperative acknowledge that rapid heating cooling processes inherent can generate excessive residual stresses within structures, thereby significantly compromising their mechanical properties. To address this issue, present study seeks...
Additive manufacturing (AM) technology has the advantages of designability, short process times, high flexibility, etc., making it especially suitable for complex high-performance components high-end industrial systems. However, intensive temperature gradients caused by rapid heating and cooling processes AM can generate levels residual stresses, which directly affect precision serviceability components. Taking Inconel 690 alloy, is widely used in nuclear power plants, as research object, a...
Rupture disc has been one of the most effective equipment to prevent overpressure from explosion for pressure equipment. The performance bursting at predetermined is critical rupture disc, which was decided directly with dimensional accuracy such as thickness, radius value and arch height. In this paper, a hydroforming FEA model established factors that affect friction coefficient, loading rate hydraulic pressure, were discussed. It found better dimension can be obtained by changing...
In order to understand the influence of a longitudinal magnetic field on microstructures superalloy DZ417G with different sample sizes, was directionally solidified under field.The solidification structures alloy various dimensions specimen have been investigated.The results showed that columnar dendrites edge samples were broken and changed into equiaxed in at withdrawal velocity 5 μm/s temperature gradient 70 ¦/cm.Additionally, it found area expanded from center number freckle-like...
