Achieving Ultra-High-Strength and Good Ductility of the ZK60 Alloy Sheet by High Strain-Rate Rolling

A superior combination of the ultra-high tensile strength (similar to 419.9 MPa), the yield strength (similar to 376.9 MPa) and the elongation (similar to 14.8%) ZK60 sheet was successfully achieved by high-strain rate rolling. The ultrahigh strength was attributed to the uniform ultrafine-grained structure. The excellent ductility was ascribed to the ultrafine grains, low dislocation density and weakened basal texture in the final structure.

Automated summary

A superior combination of ultra-high tensile strength and elongation was achieved in ZK60 sheet through high-strain rate rolling, attributed to the uniform ultrafine-grained structure and low dislocation density.
