Microstructure and texture evolution in laser Shock Peened martensitic NiTi shape memory alloy

Cyril Cayron, Roland Logé, Junfeng Xiao, Yandong Jing

The Laser Shock Peening (LSP) is commonly used to strengthen the surface of materials. However, the microstructures after LSP impact are complex due to the intense forces involved. In this study, we explore how martensitic microstructures evolve in a half ...

The role of interaction work in martensite deformation

Cyril Cayron, Roland Logé, Junfeng Xiao

This study elucidates the evolution of martensite deformation via Interaction Work (IW). The IW is the mechanical work done by external loading, assisting deformation by competing with the energy barrier. This interplay establishes the maximum IW (IWmax) c ...

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

Mathijs Pieter van der Meer, Eric Boillat, Cyril Cayron, Jamasp Jhabvala, Roland Logé, 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 ...
