Reports from Yanshan University Highlight Recent Findings in Materials Engineering (A hierarchical nanolamella-structured alloy with excellent combinations of tensile properties)

By a News Reporter-Staff News Editor at Journal of Engineering -- Data detailed on Materials Engineering have been presented. According to news reporting from Qinhuangdao, People's Republic of China, by VerticalNews journalists, research stated, "Dual phase (alpha+beta)-Ti alloys with a fully fine laminated microstructure usually exhibit a high strength but a limited ductility."

The news correspondents obtained a quote from the research from Yanshan University, "In the present study, a hierarchical nanolaminated microstructure consisting of lamellae with nano- and submicrometer-sized widths has been produced in a TiZrAIV alloy by employing severe plastic deformation (SPD) combined with subsequent thermal annealing. The hierarchical nanolamella-structured Ti alloy exhibits excellent combinations of tensile properties, e.g., an ultimate tensile strength sigma(UTS)=1600 MPa and an elongation to failure epsilon(f)=6.5%."

According to the news reporters, the research concluded: "The high strength can be attributed to the formation of a lot of nanoscale alpha lamellae in the alloy, and the enhanced ductility results mainly from both the coarse alpha lamellae that have a high strain hardening capability and the complex strain paths caused by a hierarchical nanolaminated structure."
