Mechanical Properties and Deformation Mechanisms of Advanced Metals and Alloys

Dear Colleagues,

Metallic structural materials have a wide application in the fields of automotive, rail, marine, and aerospace industry. The strength-ductility paradox has been a long-sought challenge for the metallic structural materials when strength is increased by grain refinement or cold working in the conventional homogeneous microstructure. Over the past few decades, advanced metals and alloys with superior mechanical properties have been rapidly developed, and mechanical behaviors for these advanced metals and alloys have been studied.

Advanced metals and alloys are generally obtained by tailoring microstructure or novel composition design, for achieving unprecedented mechanical properties. The aforementioned unique properties of these advanced metals and alloys originate from the synergistic effect by trans-scale microstructures, which are based on the stress–strain gradient, geometry necessary dislocations, the interaction of dislocations with new structures, and unique interfacial behavior. To date, advanced metals and alloys with heterogeneous microstructure or novel composition design have opened an avenue towards resolving the strength–ductility paradox and for understanding the relationship between superior mechanical properties and trans-scale microstructures.

The purpose of the present Special Issue is to elucidate the state-of-art of this growing research field from a fundamental and application perspective. Recent advances on mechanical properties/performance and mechanism of advanced metals and alloys would be emphasized, including strength–ductility synergy, tensile behaviors, impact behaviors, fatigue and fracture behaviors, as well as friction and wear behaviors. Because of your expertise in these fields, we cordially invite you to contribute a paper to this Special Issue. Experimental studies and simulation/modeling work are both encouraged and welcomed. The deadline for submission is 20 December 2022.
