TL;DR: Direct time-resolved imaging of melt pool flow dynamics from a high-energy synchrotron radiation experiment is presented to show surface tension affects flow speed, orientation and surface turbulence.
Scanning strategies effect on temperature, residual stress and deformation by multi-laser beam powder bed fusion manufacturing
TL;DR: In this paper, a series of computational process simulations of PBF-MLB was carried out using a 3D coupled thermomechanical model to investigate optimum multi-laser scanning strategies.

Coupled simulation of the influence of austenite deformation on the subsequent isothermal austenite–ferrite transformation
TL;DR: In this article, the influence of plastic deformation on the subsequent isothermal austenite-ferrite transformation in binary Fe-C alloys is simulated by coupling a Q-state Potts Monte Carlo (MC) method with a crystal plasticity finite element method (CPFEM).

Resolution, energy and time dependency on layer scaling in finite element modelling of laser beam powder bed fusion additive manufacturing
TL;DR: In this article, a thermomechanical PBF-LB process model including an efficient powder-interface heat loss mechanism was developed and the effect of variations in layer height (layer scaling), energy and time on the temperature and stress evolution was investigated.

Towards a process-structure model for Ti-6Al-4V during additive manufacturing
TL;DR: In this article, a finite element (FE) model of the PBF-LB process is developed for prediction of thermal history and spatial distributions of temperature, based on the relationships between FE predicted thermal history, thermal gradient and key manufacturing parameters such as laser power and scanning speed, an additive manufacturing process map for different solidification morphologies, including columnar-to-equiaxed transition, is developed.
