Abstract

Zn is a promising biodegradable metal for clinical applications. However, tensile yield strength (YS), ultimate tensile strength (UTS) and elongation (EL) of as-cast pure Zn are only 10 MPa, 18 MPa and 0.3 %, respectively. In this study, significant grain refinement and texture enhancement of pure Zn are achieved by bottom circulating liquid-cooled (BCLC) casting and rolling, which improves YS, UTS and EL of pure Zn to 103 MPa and 136 MPa and 49 %, respectively. The BCLC-rolled one reaches the highest level of comprehensive mechanical properties of pure Zn. Compared with the conventionally rolled one, the BCLC-rolled one shows significantly improved corrosion uniformity in simulated body fluid. MC3T3-E1 cell viability of the BCLC-rolled pure Zn can reach 99 %, which is 14 % higher than the conventionally rolled one. Regulating grain size and orientation during solidification will be an effective method to improve multiple properties of Zn-based materials.

通过晶粒细化和织构设计对纯锌进行多重优化

锌是一种很有前景的生物可降解金属。铸态纯Zn的抗拉屈服强度（YS）、极限抗拉强度（UTS）和伸长率（EL）分别仅为10 MPa、18 MPa和0.3%。在本研究中，通过底部循环液冷（BCLC）铸造和轧制，使纯Zn的晶粒细化和织体增强明显，使纯Zn的YS、UTS和EL分别提高到103 MPa、136 MPa和49%。bclc轧制后的锌合金综合力学性能达到纯锌合金的最高水平。与常规轧制钢板相比，bclc轧制钢板在模拟体液中的腐蚀均匀性显著提高。纯锌轧制后的MC3T3-E1细胞存活率可达99%，比常规轧制后的MC3T3-E1细胞存活率高14%。在凝固过程中调节晶粒尺寸和取向是改善锌基材料多种性能的有效方法。

期刊介绍： Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry. The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
