Study on microstructure evolution and deformation behavior of Mg– Zn base alloy pipes during hot bending [PDF]

Journal of Materials Research and Technology
The strong basal fiber texture of magnesium (Mg) alloy pipes usually leads to poor secondary forming performance. In this study, Mg–2Zn-0.4Ce-0.4Mn (ZME) and Mg–2Zn-0.4Ce-0.4Mn-0.2Ca (ZMEX) pipes were prepared.

Using a Digital Twin as the Objective Function for Evolutionary Algorithm Applications in Large Scale Industrial Processes

IEEE Access, 2023
In this paper, we describe how the up-to-date state of a digital twin, and its corresponding simulation model, can be used as a fitness function of an evolutionary algorithm for optimizing a large-scale industrial process.
