Isothermal compression experiments of vapor-grown carbon nanofiber (VGCNF)-reinforced aluminum matrix (VGCNF/Al) composites and pure aluminum (Al) were conducted at deformation temperatures from 573 K to 723 K and strain rates from 0.01 to 1 s−1. I

It is well known that the adverse effects of inclusions on the performance of a substrate are not negligible. Currently, as the level of smelting improves, the inclusion content in molten steel has been greatly reduced, but a completely pure material
