【Abstract】 M40 carbon fibers and LY12 alloys are used as raw materials in the paper. The influences of semisolid forming on the materials microstructures and properties, and the difference between semisolid forming and solid plasticity forming have been studied. The results show that the length of carbon fibers in semisolid forming is higher than that of solid forming obviously. Moreover the strength has increased a lot in semisolid state.更多还原
