What emperatures are riched by laser melting titanium?
Best insight from top research papers
Laser melting of titanium can reach extremely high temperatures, with ultrashort laser pulses capable of generating pressures up to 1000 GPa (1 TPa) . This process leads to shock-induced melting depths significantly larger than those caused by heat conduction, allowing for the formation of a solid layer with a distinct structure from the original material . Additionally, selective laser melting of titanium parts can result in the formation of nanoscale polycrystalline layers due to rapid crystallization following a melting shock wave . The temperatures achieved during laser melting are crucial for modifying the microstructure of titanium, enhancing properties like wear resistance, corrosion resistance, and mechanical strength .

What is the impact of laser beam welding on Ti6Al4V residual stress?5 answersLaser beam welding of Ti6Al4V alloy has been found to have a significant impact on residual stress. The use of pulse laser welding can reverse the residual stress from tensile to compressive, resulting in a compression state on the weld surface and mitigating overall tensile residual stress. Laser shock peening (LSP) treatment also induces compressive residual stress in Ti6Al4V alloy, with a maximum compressive residual stress of up to 800 MPa on the surface and a CRS layer with a thickness of 0.623 mm beneath the surface. Laser surface treatment of Ti alloys with an Nd:YAG laser leads to the formation of tensile residual stresses, with the highest residual stresses observed in Ti15Mo alloy. Laser shock peening with different laser intensities and peening patterns can affect the residual stress field, with an increase in laser pulse power density resulting in higher compressive stress and the occurrence of tensile stresses on the opposite side of the sample.
What heat treatment is suitable for additivelly manufactured Inconel 939?4 answersThe suitable heat treatment for additively manufactured Inconel 939 is a high-temperature solution and aging heat treatment. This heat treatment process dissolves the dendritic microstructure and precipitates semi-coherent γ’ (Ni3(Al,Ti)) precipitates, resulting in enhanced yield strength. Omitting the high-temperature solution treatment step can lead to the growth of the deleterious η phase upon aging, which results in embrittlement. High-temperature heat treatment (>1100 °C) of additively manufactured Inconel 939 samples results in recrystallized, equiaxed grains containing fcc {111} annealing twins and second phase particles, independent of the additive manufacturing process used. For Inconel 718, a solutionizing recrystallization (RC) heat treatment is suitable to improve yield strength and decrease deformation anisotropy. Additionally, a high-temperature heat treatment at 1065°C can be used to enhance the microstructure, reduce residual stress, and increase hardness in Inconel 718 fabricated through laser powder bed fusion (L-PBF).
What metallic phases does the titanium alloy consist of?5 answersThe titanium alloy consists of different metallic phases depending on the specific composition. One alloy material contains alpha phases and intermetallic compounds. Another alloy part includes alpha-phase crystal grains and beta-phase crystal grains. A non-limiting embodiment of a titanium alloy comprises an alpha phase and other alloying additions to stabilize the alpha phase and increase its volume fraction. In a titanium-molybdenum alloy, a non-classically nucleated metastable phase bridges the alpha phase and the beta phase.
What is the mechanism by which laser remelting affects the microstructure distribution and tribological properties of steel?5 answersLaser remelting affects the microstructure distribution and tribological properties of steel through various mechanisms. Laser surface remelting leads to the recrystallization of the structure, resulting in a denser and finer microstructure with reduced grain size. This leads to an increase in hardness and improved tribological properties, such as wear resistance and impact resistance. Laser remelting also enhances the mechanical properties of the steel by inducing grain refinement, dislocation strengthening, and precipitation strengthening. The laser treatment process confers a high hardness at the surface of the steel workpiece, improving its surface quality and mechanical properties. Additionally, laser remelting eliminates surface defects like porosity, cracks, and splat boundaries, further improving the microstructure and tribological properties of the steel. Overall, laser remelting is an effective technique for enhancing the microstructure distribution and tribological properties of steel.
