Ultrasound can improve the quality of finished products by reducing porosity and enhancing microstructure in selective laser melting, directed energy deposition, beam welding. This study evaluates efficiency ultrasound produced a pulsed via optoacoustic effect. A quantitative model collapse vapor-gas bubbles has been developed under conditions ultrasonic treatment at near resonance frequencies. Based on simulation results, phenomenological expressions are suggested to determine optimal...
The motion of a solder inside ceramic tube with an aluminum insert is considered using the phase-field model multiphase flows. problem solved in non-isothermal formulation, which allows analyzing two-phase flow dynamics and kinetics contact line driven by wetting. total time required for to heat up, melt then move calculated accounting its position action wetting forces. melting taken into account system through introduction effective capacity as function temperature. values dimensionless...
Selective laser melting (SLM) technology has the advantage of quickly producing complex-shaped parts. To achieve good mechanical properties, it's vital to minimize defects that can occur because high residual porosity if incorrect processing techniques are used. One effective way prevent is by using computer simulations underlying processes before printing in industry. This paper presents a reduced-order numerical model SLM accurately predicts material focusing on key mechanisms affect and...
A new mechanism for controlling the microstructure of products in manufacturing processes based on selective laser melting is proposed. The relies generation high-intensity ultrasonic waves melt pool by complex intensity-modulated irradiation. experimental study and numerical modeling suggest that this control technically feasible can be effectively integrated into design modern machines.
The problem of surface processing and microstructure refinement in stainless steels laser the presence an external magnetic field has been studied experimentally theoretically. effect both alternating permanent fields is discussed. experimental part includes assessment a thin plate annealed by quasi-continuous electromagnetic acoustic transducer. Complementary analytical calculus numerical simulations complex transport phenomena melting zone are performed. Based on received data, molten...
Phase field (diffuse interface) models accommodate diffusive triple line motion with variable contact angle, thus allowing for the no-slip boundary condition without stress singularities. We consider two commonly used classes of phase models: compositionally compressible (CC) model compressibility limited to fluid mix within diffuse interface, and incompressible (IC) model. First, we show that CC applied fluids dissimilar mass densities exhibits computational instability leading breakup...
The importance of the problem hole-filling by a molten metal lies in application brazing for repairs space, under microgravity conditions. negligible effects gravity and dominance capillary forces can be approximated terrestrial conditions, provided that hole quantity liquid are small, as quantified Bond number. In this paper, we report experimental results, modeling, analysis using aluminum alloy on substrate. Depending size, driven flow may result being either filled or not filled....
