Manipulating A2/B2 microstructure via adjusting Al/Ni ratio in cost-effective Fe-based AlNiFeCr alloys for controllable strength-plasticity combination Mater. Charact. (IF 4.7) Pub Date : 2024-03-19 Guijiang Diao, Mingyu Wu, Zhen Xu, Q.Y. Li, Dongyang Li
Cost-effective Fe-based Al-Cr-Fe-Ni alloys were prepared by arc melting process, and Al/Ni ratio in AlNiFeCr (0 ≤ ≤ 40, at.%) alloys was adjusted for superior mechanical properties. With increasing , the initial FCC phase diminishes and A2/B2 phase is promoted. Two typical A2/B2 structures are observed, one consists of spherical/cuboidal B2 nanoparticles distributed in A2 matrix (denoted as AMBP),

Substitutional and interstitial atoms co-doping overcomes the strength–ductility trade-off in lightweight refractory medium-entropy alloys Mater. Charact. (IF 4.7) Pub Date : 2024-03-19 Yongmiao Liu, Mingliang Wang, Tongmin Wang, Tingju Li, Yiping Lu
Interstitial or substitutional solid solution strengthening is a common method for enhancing material mechanical properties, however, it is unclear whether their synergy can lead to better mechanical properties in materials. Here, we have demonstrated that the synergy of interstitial and substitutional elements can overcome the strength-ductility trade-off, which was substantiated in an O and Al co-doping

High-throughput pseudo-binary diffusion couple approach for alloy design in cobalt-based superalloys Mater. Charact. (IF 4.7) Pub Date : 2024-03-19 Muni Kumar Kandula, Mahander Pratap Singh, Esakkiraja Neelamegan, Aloke Paul, Chattopadhyay Kamanio
The paper describes a high-throughput method for alloy design in in Co-based superalloy. The approach is an extension of the diffusion couple method used for the determination of diffusion coefficients. We present the use of such a method in low-density cobalt-based superalloys Co-30Ni-10Al-5Mo-2Ta-2Ti-xCr (x = 0–14 at. %) exploring the effect of Cr content on the microstructural evolution, mechanical
