Ultrafine-grained and heterostructured materials are currently of high interest due to their
superior mechanical and functional properties. Severe plastic deformation (SPD) is one of …

Forming alloys with impurity elements is a routine method for modifying the properties of
metals. An alternative approach involves the incorporation of interfaces into the crystalline …

Metallic wires with high strength-ductility at both room and cryogenic temperatures are
always pursued for engineering applications. However, traditional metallic wires are tortured …

Abstract Interstitials, eg, C, N, and O, are attractive alloying elements as small atoms on
interstitial sites create strong lattice distortions and hence substantially strengthen metals …

Nanostructured metals and alloys often exhibit high strengths but at the expense of reduced
ductility. Through harnessing the far-from-equilibrium processing conditions of laser powder …

We report on the strengthening and strain hardening mechanisms in an aged high-Mn
lightweight steel (Fe-30.4 Mn-8Al-1.2 C, wt.%) studied by electron channeling contrast …

The segregation of transition metal elements to grain boundaries in steels plays a critical
role in determining their cohesion. Here, we investigate the segregation, co-segregation …

This chapter report a detailed study of the strain hardening behavior of a Fe-16Mn-10Al-0.86
C-5Ni high specific strength steel (HSSS) during uniaxial tensile deformation. The tensile …

Experiments have shown that a gradient design, in which grain size spans over four orders
of magnitude, can make strong nanomaterials ductile. This chapter presents a developed …

We study grain boundary embrittlement in a quenched and tempered Fe–Mn high-purity
model martensite alloy using Charpy impact tests and grain boundary characterization by …
