Influence of Joule Effect Heating on Recrystallization Phenomena in Inconel 718

Roland Logé, Mathijs Pieter van der Meer

In this article, the Joule effect heating influence on recrystallization phenomena in the Inconel 718 nickel-based superalloy is investigated in details. On the one hand, static recrystallization kinetic studies at 1020 degrees C after cold deformation up ...

Acoustic emission signature of martensitic transformation in laser powder bed fusion of Ti6Al4V-Fe, supported by operando X-ray diffraction

Roland Logé, Jamasp Jhabvala, Mathijs Pieter van der Meer, Milad Hamidi Nasab, Reza Esmaeilzadeh, Claire Navarre, Charlotte Léopoldine de Formanoir de la Cazerie, Lucas Maximilian Schlenger

This study focuses on investigating Acoustic Emission (AE) monitoring in the Laser Powder Bed Fusion (LPBF) process, using premixed Ti6Al4V-(x wt%) Fe, where x = 0, 3, and 6. By employing a structure-borne AE sensor, we analyze AE data statistically, uncov ...

Toward Architected Microstructures Using Advanced Laser Beam Shaping in Laser Powder Bed Fusion of Ti-6al-4v

Roland Logé, Cyril Cayron, Jamasp Jhabvala, Eric Boillat, Mathijs Pieter van der Meer, Reza Esmaeilzadeh, Lucas Maximilian Schlenger, Seyed Amirmohammad Jamili, Junfeng Xiao

Laser Powder Bed Fusion (LPBF) stations mostly use lasers with a Gaussian beam intensity distribution, as it has advantages like small divergence and high ability to be focused. This distribution creates significant thermal gradients leading to high coolin ...

Wire-sawing processes: parametrical study and modeling

Christophe Ballif, Mathijs Pieter van der Meer

Reducing the wafer breakage rate without changing the wafer thickness and sawing thinner wafers while maintaining constant breakage rate are two possibilities to decrease the costs of solar cells. They are similar in the sense that both require stronger wa ...

EBSD study of variant reorientation, texture, and twin formation in a martensitic NiTi alloy deformed in compression

Junfeng Xiao, Roland Logé, Cyril Cayron, Mathijs Pieter van der Meer

Martensitic crystallography plays a vital role in the texture evolution and mechanical properties in Nickel-Titanium (NiTi) shape memory alloys when subjected to deformation. However, their microstructural changes during deformation are not well known and ...

Influence of abrasive concentration on the qualiy of wire-sawn silicon wafers

Christophe Ballif, Mathijs Pieter van der Meer

The sawing parameters have an impact on the depth of the defects in the wafers, and hence on their mechanical strength. However, as sawing is a highly complex system, the wafering industry is still relying on a “trial and error” approach to improve the saw ...

Effects of edge defects induced by multi-wire sawing on the wafer strength

Christophe Ballif, Mathijs Pieter van der Meer

The focus of the photovoltaic industry is a continuous reduction of the cost of solar energy. Lowering the wafer thickness during the processing by means of multi-wire slurry saw technology is one of the key issue to reduce these costs. However, reducing t ...

Strain-induced dissolution of Y-Ti-O nano-oxides in a consolidated ferritic oxide dispersion strengthened (ODS) steel

Roland Logé, Mathijs Pieter van der Meer

The present study shows the influence of severe plastic deformation on highly stable Y-Ti-O nano-oxides present in ferritic ODS alloys used for nuclear applications. An innovative strain path implying alternated compressions was used to deform the material ...

Mechanisms of wafer sawing and impact on wafer properties

Christophe Ballif, Johann Michler, Mathijs Pieter van der Meer

Silicon wafer wire-sawing experiments were realized with different sets of sawing parameters, and the thickness, roughness, and cracks depth of the wafers were measured. The results are discussed in relation to assumptions underlying the rolling-indenting ...
