During the multi-laser powder bed fusion (ML-PBF) process, quality of overlap region is essential to ensure integrity between different laser scanning areas. Here, six widths (ORWs) are selected systematically investigate effect ORWs on densification, metallurgical defects, crystalline microstructure, and mechanical performance Hastelloy X samples processed by fusion. set 0, 50, 100, 150, 200, ...

Choosing a properly optimized rotating scan strategy during the selective laser melting (SLM) process is essential to reduce residual stresses and thus obtain homogeneous properties. Surprisingly, anisotropic material properties are found in several materials that built with often applied stripes of Electro-Optical Systems (EOS) because avoids possible interactions beam by-products therefore ex...

Cutting force is vital in machining nickel-based superalloys due to their excellent mechanical properties, thus creating difficulty cutting. In the current scenario of metal machining, milling processes require high spindle speed and low chip load, which result a cutting force. However, load not only but also material removal rate (MRR). It contrary ultimate high-speed (HSM) goal, improve produ...

There is a growing demand to produce parts from Hastelloy-X materials, which exhibit high unit cost per weight, by the selective laser melting (SLM) process. However, when material was employed, solidification crack occurred during SLM This cracking can be reduced or eliminated optimizing process parameters, such as power and scan speed, although optimization time- cost-intensive. In this study...

The presence of random defects in laser powder bed fusion (LPBF) parts is an issue that challenges the reliability this manufacturing process and hinders its employment structural, defect-sensitive components. A potential solution to increase LPBF employing in-process monitoring targeting defect detection. This study aims detect stochastic driven by spatter particles via in-situ validate detect...

The present study investigates the influence of a rescanning strategy on microstructure and mechanical properties Hastelloy X samples manufactured by laser powder bed fusion process in additive manufacturing. After first lasing leading to melting, second is performed solid metal with five considered powers corresponding 100-80-60-40 20% power scan. obtained from these elaboration strategies wer...

Thin Pd–Ag layers have been successfully deposited on ceramic supports with controlled surface characteristics. The need for less fragile membranes and ease of sealing connection leads to the study metallic thin Pd-based membrane development. Metallic supported are prone intermetallic diffusion issues so an interdiffusion barrier must be introduced. However, sufficient quality direct deposition...
