RELATIONSHIP BETWEEN SURFACE MARTENSITE, THIN FOIL AND BULK MARTENSITE

open access: yesLe Journal de Physique Colloques, 1982
The possibility that surface martensite can serve as nucleus for bulk martensite is investigated by transmission electron and light microscopy in ternary Cu-Zn-Al alloys. For this reason the relationship of the variants and structures between surface martensite, thin foil and bulk martensite is studied. It is known that the surface martensite can serve

Effects of Shot‐Blasting and Induction Hardening on the Fatigue Strength of Hot‐Forged Wheel Bearing Hubs

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 8, Page 3353-3367, August 2025.
ABSTRACT Hot‐forged wheel bearing hubs are manufactured using a complicated fabrication process chain to obtain the desired microstructure and mechanical properties in different zones that experience varying local stress states. The different process steps modify the surface roughness and the residual stresses distribution and therefore affect the ...

The Influence of Rapid Tempering on the Mechanical and Microstructural Characteristics of 51CrV4 Steel

open access: yesMetals
The microstructure and mechanical properties of a low-alloy medium carbon steel (Fe-0.5C-0.9Mn-1Cr-0.16V, in wt.%) were investigated after rapid tempering and compared with a conventionally tempered counterpart.

Assessing the fatigue resistance of NiTi instruments: A DSC‐based approach to understanding temperature effects

open access: yesInternational Endodontic Journal, Volume 58, Issue 8, Page 1267-1276, August 2025.
Abstract Aim This study aims to demonstrate that phase transformation analysis, assessed via differential scanning calorimetry (DSC), offers a more comprehensive understanding of NiTi instruments' mechanical behaviour than traditional fixed‐temperature fatigue testing by evaluating phase transformation temperatures and their impact on cyclic fatigue ...

Effect of Thermomechanical Processing on the Impact Deformation of Additively Manufactured 316L Stainless Steel

open access: yesAdvanced Engineering Materials, Volume 27, Issue 13, July 2025.
Previous studies on additive manufacturing primarily focus on the mechanical properties of as‐printed components. In the present work, researchers explore the potential of employing novel thermomechanical postprocessing techniques to improve the microstructure after printing.

Nitinol in Orthopedic Applications: Clinical Insights, Performance Challenges, and Future Directions

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, Volume 113, Issue 7, July 2025.
ABSTRACT The increasing prevalence of spinal disorders has spurred continuous innovation in implant design and biomaterials. Among emerging options, Nitinol has gained significant interest due to its unique combination of shape memory effect, superelasticity, and mechanical compatibility with bone tissue.
