Residual strains in AA2024/AlSiCp composite linear friction welds
Materials & Design, 2010 The present paper is devoted to the study of residual strains in AA2024/AlSiCp linear friction welds, using a novel approach based on eigenstrain. Synchrotron X-ray and neutron diffraction were used to measure the interplanar lattice spacing in the welds and deduce the residual elastic strains as a function of the distance from the bond line.

Mixing Behavior of Natural Gas and Hydrogen in a High‐Efficiency Vane (HEV) Static Mixer
Energy Science &Engineering, EarlyView.Static mixers play a crucial role in the safe transport of hydrogen‐blended natural gas. Computational fluid dynamics (CFD) was employed to investigate the effects of structural parameters of the HEV static mixer on the mixing behavior and homogeneity of natural gas and hydrogen. The modeling approach was well validated against experimental data.

Optimization of Welding Condition for Nonlinear Friction Stir Welding
MATERIALS TRANSACTIONS, 2007 The influence of nonlinear friction stir welding (FSW) tool control on joints' mechanical properties was investigated. Although FSW is widely applied to linear joints, it is impossible for five-axis FSW machines to maintain all FSW parameters in optimum conditions during nonlinear welding.
