Abstract The microstructures and corrosion resistance of electromagnetic stirring (EMS) semi-solid slurry as-cast 7A04 aluminum alloy were compared in this work. results show that the primary microstructure is mainly dendritic columnar dendrite with obvious elements segregation. In contrast, processing can effectively form homogeneous round α -Al grains, significantly reducing element addition, main phases two forming methods (as-cast semi-solid) both involved -Al, η -MgZn 2 , θ Cu. With...
Lactic acid is an important platform compound used as raw material for the production of lactide and polylactic acid. However, its concentration composition distribution are not simple those common compounds. In this work, mass highly concentrated lactic determined by back titration. The components acid, crude lactide, polymer after reaction analyzed HPLC. Different concentrations solution were prepared synthesis content in product was 1 H NMR analysis. We found that more easily produced...
