The Hidden Dangers of Counterfeit and Replica‐Like Endodontic Files: A Scoping Review of Current Evidence

Australian Dental Journal, EarlyView.
ABSTRACT This scoping review mapped and critically appraised laboratory evidence on counterfeit and replica‐like nickel–titanium endodontic files, evaluating design, metallurgical composition, surface finishing, and mechanical performance to clarify clinical and regulatory implications.

Cyclic Plastic Material Behavior of Novel Austenitic (C + N) Steel Additively Manufactured by PBF‐LB/M

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The newly introduced high manganese high strength (C + N) steel Printdur HSA was developed for the additive manufacturing process PBF‐LB/M. It consists of a fully austenitic grain structure. This study aims to evaluate the cyclic plastic material behavior of this (C + N) steel.

Kinetics of martensitic transformations in magnetic field or under hydrostatic pressure

Science and Technology of Advanced Materials, 2011
We have recently constructed a phenomenological theory that provides a unified explanation for athermal and isothermal martensitic transformation processes. On the basis of this theory, we predict some properties of martensitic transformation and confirm

Deformation and martensitic transformation

Bulletin of Materials Science, 1984
The influence of applied stresses and imposed plastic deformation on the martensitic transformation of a parent phase is described. Changes in mechanical properties such as flow stress, work hardening rate, fracture toughness, etc brought about by strain-induced martensitic transformation are briefly examined.

Influence of Dual Heat Treatment on the Metallurgy and Mechanical Behaviour of Diamond‐Like Carbon–Coated NiTi Rotary Systems: A Multimethod Investigation

International Endodontic Journal, EarlyView.
ABSTRACT Aim To investigate how the application of dual heat treatment during the manufacturing process influences the mechanical performance (flexibility, cyclic fatigue resistance, torsional strength, bending, buckling and cutting efficiency) of rotary nickel‐titanium endodontic instruments. Methodology Rainbow One (n = 58) and Rainbow Ultra (n = 58)
