Achieving a corrosion-resistant Mg-Ca lean alloy by solidification control to sequester parts-per-million-level Fe impurity

open access: yesnpj Materials Degradation
The influence of solidification cooling rate on the microstructure, particularly Fe-rich particles, in a Mg-0.1Ca (wt%) alloy is studied, as well as the corresponding effect on the corrosion resistance. It is revealed that a slow cooling rate (

Analysis of quality defects in the fracture surface of fracture splitting connecting rod based on three-dimensional crack growth

open access: yesResults in Physics, 2018
Quality defects of fracture surface are easily produced in the fracture splitting process of connecting rod. At present, the resulting mechanism of this type of defect is lacking in evidence and there is no effective control method.
