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

open access: yesMaterials 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 ...

Experimental Evaluation of Turning AISI 304 Using Minimum Quantity Lubrication With Vegetable‐Based Green Cutting Fluids

open access: yesMetalMat, EarlyView.
This study experimentally evaluates the performance of eco‐friendly vegetable‐based cutting fluids—coconut, sunflower, and palm oils—during turning of AISI 304 stainless steel under minimum quantity lubrication. Palm oil exhibited superior lubrication and cooling characteristics, yielding the lowest cutting force, temperature, and surface roughness ...
