A carbide-reinforced Re0.5MoNbW(TaC)(0.8) eutectic high-entropy composite with outstanding compressive properties

期刊: SCRIPTA MATERIALIA, 2021; 200 ()

Refractory high-entropy alloys are promising high-temperature materials owing to their excellent softening resistance. However, most RHEAs that can wi......

Nanoparticle enabled high performance high modulus steels

期刊: SCRIPTA MATERIALIA, 2021; 201 ()

Here we present a novel concept that uses a low volume fraction of nanoparticles to nano-treat Fe-Ti-B melts for a new high performance high modulus s......

In-situ TEM investigation of unfaulting behavior of Frank loops in FCC Pd during H-2(+) & He+ dual-beam irradiation

期刊: SCRIPTA MATERIALIA, 2021; 203 ()

A faulted Frank dislocation loop (FDL) can transform into an unfaulted perfect dislocation loop (PDL) under plastic deformation, quenching or particle......

Cyclic response of additive manufactured 316L stainless steel: The role of cell structures

期刊: SCRIPTA MATERIALIA, 2021; 205 ()

We report the effect of cell structures on the fatigue behavior of additively manufactured (AM) 316L stainless steel (316LSS). Compared with the cell-......

Microstructure and strengthening mechanisms of nanolamellar structures in ultrastrong drawn iron wires

期刊: SCRIPTA MATERIALIA, 2021; 200 ()

Ultrastrong pure iron wires have been produced with a strength of 1.8 GPa with a strain of 10.35. Based on microstructural observation and quantified ......

On temperature and strain-rate dependence of flow serration in HfNbTaTiZr high-entropy alloy

期刊: SCRIPTA MATERIALIA, 2021; 200 ()

Plastic instability manifested as the serrated flow on stress-strain curves of metal alloys is generally detrimental to their processing and manufactu......

A new insight into annealing parameters in tailoring the mechanical properties of a medium Mn steel

期刊: SCRIPTA MATERIALIA, 2021; 202 ()

Generally, the mechanical properties of medium Mn steels are mainly tailored by adjusting temperature and duration of intercritical annealing (IA). Ho......

The environmental degradation behavior of FeNiMnCr high entropy alloy in high temperature hydrogenated water

期刊: SCRIPTA MATERIALIA, 2021; 204 ()

Co-free high entropy alloy (HEA) 28%Fe-27%Ni-27%Mn-18%Cr shows good irradiation resistance and could be a potential candidate for structural material ......

Interfacial phases formed in friction stir lap welding high entropy alloy to Al alloy

期刊: SCRIPTA MATERIALIA, 2021; 201 ()

The formation of intermetallic compounds (IMCs) at the joint interface between dissimilar metals has been the focus of recent research, since joint pr......

Work hardening discrepancy designing to strengthening gradient nanotwinned Cu

The purpose of this study is to identify the high-temperature oxidation mechanisms of a Ti2AlNb-based alloy via detailed analyses of oxide scale/subst......

Interfaces Reduce Dislocation Loop Formation in Irradiated Nanolayered Zr-2.5Nb

期刊: SCRIPTA MATERIALIA, 2021; 200 ()

Interface engineering is a useful method to reduce the accumulation of irradiation defects in metals. Here, we study the effect of interface on the fo......

Electromigration-enhanced atomic diffusion to improve coating interface bonding

期刊: SCRIPTA MATERIALIA, 2021; 202 ()

The chromium-coated zirconium alloy has a conflicting problem that the diffusion layer that enhances the interface bonding force cannot be formed due ......

Studies of Cu-Sn interdiffusion coefficients in Cu3Sn and Cu6Sn5 based on the growth kinetics

期刊: SCRIPTA MATERIALIA, 2021; 204 ()

In this work, we set up a kinetic model of Cu3Sn (epsilon) and Cu6Sn5 (eta) growth based on the reaction/diffusion theory. The kinetic equations of th......
