Stability mechanism of AlSi12 aluminum foam under the action of Al–Si–Ca second phase
Journal of Materials Research and Technology, 2021 AlCa75 with equal Ca content was used to replace pure Ca for the preparation of AlSi12 foam in a stable pore structure after foaming for 20 min. The stability mechanism was studied based on the comparison between the macroscopic pore structure evolution ...

Advanced Engineering Materials, Volume 25, Issue 21, November 2023., 2023 Assessment of fatigue fracture surface images is commonly done manually by experts. Although this leads to correct results, it has several disadvantages, for example, the need of a huge knowledge base. Therefore, an unsupervised tool for analysis of overview images of fatigue fracture surfaces is developed to support nonexperienced users to identify ...
