TL;DR: In this paper, a coupled set of experiments and numerical simulations using the commercial finite element code ABAQUS/Explicit was used to study the evolution of redundant strains in a single-roller flow forming process in one pass.

TL;DR: In this article, an accumulative spin-bonding (ASB) process was proposed for manufacturing high strength tubes and cylinders by accumulating spinbonding, which was applied to a commercially pure aluminum up to four cycles and its effects on the microstructure and mechanical properties were examined by optical microscopy.

TL;DR: In this paper, the effects of process temperature, thickness reduction, feed rate and roller attack angle as the parameters of tube spinning on the bond strength have been studied, and it has been shown that the strength increases by increasing the thickness reduction and process temperature.

TL;DR: In this article, the authors investigated the flow behavior of ultrafine grained AA 1050 sheets processed by ARB and its viscous nature by plane strain compression test (PSC) along with stress relaxation.

TL;DR: In this article, a new approach is developed to integrate a particle-based (seed crystals) nucleation mechanism into the cellular automata (CA) simulation of powder-bed laser beam melting, which aims to reflect two features observed in the microstructures of additively manufactured Al alloys: the fusion boundary nucleation which violates the principle of common bulk nucleation favored under high solidification rates and low thermal gradients, and the epitaxial growth at the melt-pool bottom.
