Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...

Investigation of Lath and Plate Martensite in a Carbon Steel

, 2011
Martensite in carbon steels forms in different morphologies, often referred to as lath andplate martensite. The alloy composition has a strong effect on the morphology, for instance in car-bon steels there is a morphological change of the martensite ...

Seismic Performance of Reduced‐Strength Steel MRFs With SMA‐Based Superelastic Friction Dampers: An Experimental Investigation

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Shape memory alloys (SMAs) exhibit excellent self‐centering capability due to their stress‐induced phase transformation, making them highly suitable for applications in resilient infrastructure. This study investigates the seismic performance of reduced‐strength moment‐resisting frames (MRFs) equipped with SMA‐based superelastic friction ...

Acoustic Activity of Intergranular Corrosion Sensitized AISI 304L in Double‐Loop Electrochemical Potentiodynamic Reactivation Test

Materials and Corrosion, EarlyView.
Intergranular corrosion of AISI 304L is analyzed, combining DLEPR test and AE. Slow scan rate polarization reveals time‐shifted and frequency‐dependent acoustic emission in the active region of the DLEPR curve, allowing a separation between passive oxide rupture, intergranular corrosion and pitting. ABSTRACT Intergranular corrosion (IGC) susceptibility

The constitution of martensite volume fraction in Fe-31wt%Ni-0.02wt%C

Journal of Materials Research and Technology, 2019
This paper analyzes the constitution of martensite volume fraction, that is, the size-distribution of martensite units in quenched-transformed austenite in the microstructure. We correlate this distribution to the martensite shape-strain relaxation.

Controlling the work hardening of martensite to increase the strength/ductility balance in quenched and partitioned steels

Materials & Design, 2017
The role of retained austenite on tensile behavior in quenched and partitioned (Q&P) steels has been studied extensively, but the deformation behavior of martensite, which comprises the majority of Q&P microstructures, has received less attention.
