Micromechanical simulations of additively manufactured aluminum alloys

V Romanova et al.

Summary: This study presents a computational approach to simulate the deformation response of additively manufactured aluminum alloys, generating a three-dimensional microstructure with the grain geometry typical for aluminum alloys produced by selective laser melting. The grain behavior is described using crystal plasticity and a phenomenological equation, providing a microstructure-based constitutive model for simulations of quasistatic tension.

Advances in the understanding of the annular laser beam wire cladding process

Matjaz Kotar et al.

Summary: This paper experimentally investigates the influence of process parameters on stability and geometry in ALB-WC process, particularly focusing on the relationship between laser beam power, WIPN parameter, and velocities. The results show that the stability region is affected by the generated clad height, and the dilution ratio is linearly correlated with temperatures. The complex influences of process parameters on stability and clad geometry are explained through a phenomenological description supported by visual and IR images.

Wire based plasma arc and laser hybrid additive manufacture of Ti-6Al-4V

Chong Wang et al.

Summary: A novel wire based plasma transferred arc (PTA)-laser hybrid additive manufacture process was proposed for high-speed deposition of large-scale titanium parts. The results showed that the hybrid process has higher deposition rate and better wire positioning accuracy, making it suitable for manufacturing engineering parts.

Influence of a closed-loop controlled laser metal wire deposition process of S Al 5356 on the quality of manufactured parts before and after subsequent machining

Dina Becker et al.

Summary: This paper discusses the interdependence between additive and subtractive manufacturing processes, using closed loop control to achieve optimal part accuracy and minimal wall thickness during additive manufacturing. Final part shapes are achieved through subsequent machining processes with minimized material removal, dependent on the initial state determined by the additive process. Understanding the relationship between generative parameters and component properties, as well as the interdependency between additive and subtractive processes, is crucial for tuning the former to the latter.
