Increasing the Reuse Potential of High‐Strength Steels by Extending the Fatigue Life through Surface Treatments

steel research international, Volume 97, Issue 8, Page 4326-4336, August 2026.
Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse.

Case depth in SAE 1020 steel using barkhausen noise [PDF]

Materials Research, 2013
The most widely used thermochemical process for surface hardening of steels is case hardening. Using several different heat treatments, martensitic surface layers were formed on SAE 1020 steel into which carbon had been diffused.

Monitoring of Surface Damage in Rails After Long Term Cyclic Loading

Communications, 2017
This paper reports about possible concept in which surface damage of the rail after long tem cyclic loading can be executed. This study employs non destructive magnetic Barkhausen noise as a promising technique which exhibits very good sensitivity ...

Evaluation of the Residual Stress State of 42crmo4 Steel Sheets in a Production Line [PDF]

Materials Research, 2016
The residual stress state of a mechanical component is an important factor in its production planning and in estimates of its lifecycle since it can be responsible for geometric distortions and degradation of fatigue properties.

Integrated Field‐Free SOT Domain‐Wall Synapses and MTJ Stochastic Neurons for Hardware Boltzmann Machines

Advanced Functional Materials, Volume 36, Issue 61, 30 July 2026.
Field‐free spin‐orbit torque domain‐wall synapses integrated with stochastic MTJ neurons enable compact hardware Boltzmann machines. Leveraging intrinsic stochasticity and multi‐level conductance, the system achieves efficient probabilistic learning with high accuracy, demonstrating a scalable spintronic platform for energy‐efficient edge AI.

Impedance Spectroscopy of Bifurcation Oscillations in S‐Type Self‐Oscillatory Devices

Advanced Physics Research, Volume 5, Issue 7, July 2026.
Impedance spectroscopy (IS) reveals stability regimes and bifurcation dynamics in S‐type self‐oscillatory devices. By linking nonlinear control theory with frequency‐domain measurements, experimental signatures of oscillations, entrainment, and phase locking are directly identified.

Influence of Demagnetization and Microstructure Non-Homogeneity on Barkhausen Noise in the High-Strength Low-Alloyed Steel 1100 MC

Applied Sciences
This study deals with two different aspects of the high-strength low-alloyed 1100 MC steel. The first is associated with the remarkable heterogeneity (linked with surface decarburization) in the surface state produced during sheet rolling with respect to

Avalanches, Barkhausen Noise, and Plain Old Criticality [PDF]

Physical Review Letters, 1995
We explain Barkhausen noise in magnetic systems in terms of avalanches near a plain old critical point in the hysteretic zero-temperature random-field Ising model. The avalanche size distribution has a universal scaling function, making non-trivial predictions of the shape of the distribution up to 50\% above the critical point, where two decades of ...

Experimental Evidence for a Metal‐Related Function of a Cyanobactin

Angewandte Chemie International Edition, Volume 65, Issue 25, 15 June 2026.
Cyanobactins such as patellamides are produced by cyanobacteria profusely and have been studied extensively, but almost exclusively for their cytotoxic properties. Discussed is unprecedented experimental evidence for a metal‐related biological function – likely CO2 transport from the ascidian to the cyanobacterial symbiont.
