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 controls rare earth enrichment in carbonatite?
5 answers
Rare earth element (REE) enrichment in carbonatites is primarily controlled by various mechanisms such as fractional crystallization, contamination processes, and hydrothermal interactions. Fractional crystallization plays a crucial role in enriching REEs in carbonatitic magmas by differentiating elements into calcite phases. Additionally, contamination from silicate wall rocks can lead to REE enrichment through processes like Raleigh volatilization and CO2 degassing. Hydrothermal fluids exsolved from late-stage carbonatitic magmas can dissolve primary carbonates, precipitate REEs, and form REE-bearing minerals like fluorocarbonates. Furthermore, postmagmatic hydrothermal dissolution of REEs from minerals like fluorapatite and pyrochlore contributes to REE mineralization in carbonatites. These processes collectively drive the enrichment of REEs in carbonatite deposits worldwide.
How do procyclical and countercyclical fiscal and monetary policies affect macroeconomic stress?
5 answers
Procyclical fiscal and monetary policies tend to exacerbate macroeconomic stress by reinforcing cyclical fluctuations. In contrast, countercyclical fiscal policies, especially when complemented with active monetary policy, can mitigate stress by stabilizing the economy. The asymmetric effects of monetary policy shocks during low and high financial stress regimes show that contractionary monetary policy has a stronger impact during high stress, while expansionary policy can boost output. Additionally, the stability and uniqueness of equilibria depend on the cyclicality of fiscal policy, with countercyclical policies requiring more aggressive debt consolidation and active monetary policy to be effective. Integrating robust control and dynamic game theory with wavelet decomposition reveals that a minimax worst-case fiscal and monetary policy model can lead to larger deficits and hinder long-term capital accumulation, increasing macroeconomic stress.
Viscosity of xylithol?
4 answers
The viscosity of xylitol can be influenced by its composition.
