Precise Design and Preparation of Metals with Strength-plasticity Synergy

doi:10.3901/JME.2021.16.329

Abstract

Abstract: Developing a metal with strength-plasticity synergy is always a goal and research focus in the field of structural metals due to the longstanding strength-plasticity trade-off. Microstructure regulation provides an effective method of designing metals with strength-plasticity synergy. Research progress on the strength-plasticity synergy designing based on grain microstructure regulation in recent years is reviewed. The mentioned microstructures involve homogenous nano/ultrafine grained structure, heterogeneous structure, and gradient nanostructure. Moreover, the strategy of the strength-plasticity synergy designing based on grain microstructure regulation combined with other methods is also introduced. The preparation methods of the different microstructures are reviewed. Finally, perspectives and challenges on the strength-plasticity synergy designing are addressed.

Key words: strength, plasticity, ultrafine grain, nanograin, heterogeneous structure, gradient nanostructure
