A Comparative Study Between NiTi and a New Flash Treated Superelastic Ti‐Zr‐Nb‐Sn Alloy for Cardiovascular Stents

Materials and Corrosion, EarlyView.
The findings presented in this manuscript recommend the Ti‐22Zr‐11Nb‐2Sn alloy as a possible alternative to Nitinol for use in biomedical devices, especially in the large‐scale manufacturing of self‐expandable vascular stents used in angioplasty. ABSTRACT Nowadays, for applications such as coronary stents, the most widely used materials are Nitinol or ...

Towards the ab initio based theory of the phase transformations in iron and steel [PDF]

, 2017
Despite of the appearance of numerous new materials, the iron based alloys and steels continue to play an essential role in modern technology. The properties of a steel are determined by its structural state (ferrite, cementite, pearlite, bainite ...

Electrochemical and Surface Insights Into X12CrMoWVNbN10‐1‐1 Steel Corrosion in Chloride Solutions at Variable pH

Materials and Corrosion, EarlyView.
The corrosion performance of X12CrMoWVNbN10‐1‐1 steel in chloride environments dramatically depends on pH. Acidic conditions trigger intense surface degradation, whereas neutral and alkaline media foster the formation of a compact and stable passive film, drastically reducing both general and localized corrosion.

Stress-induced α″ martensite and its variant selection in a metastable β titanium alloy under an uniaxial compression

Journal of Materials Research and Technology
The phase transformation of β to stress-induced α″ martensitic progresses in a displacive mode. The associated transformation strain induced by β to α″ martensitic has an important influence on the resultant microstructure.

Designing High‐Entropy Alloys With Low Stacking Fault Energy Through Interpretable Machine Learning

Materials Genome Engineering Advances, EarlyView.
In this study, we developed an interpretable machine learning (ML) ensemble framework and, by integrating the VEC criterion with the proposed machine learning scoring parameter in the alloy composition screening process, successfully designed multiple CoCrFeNiMn‐based HEAs with TWIP/TRIP effects and without the BCC phase.
