Variations of VHCF Characteristics by Microstructure of a Spring Steel to UNSM Treatment
The bainitic structure resulting from the austempering of spring steel exhibits high strength and ductility. On the other hand, there appears to be no study on the effects of very high cycle fatigue (VHCF) and ultrasonic nanocrystal surface modification (

This study validates a recycling pathway for converting interconnect assemblies from end‐of‐life SOC stacks into commercial‐grade AISI 304 steels. Using scrap‐based steelmaking operations, austenitic cast steels with <4.0% δ‐ferrite are successfully produced.

Numerical thermo-elasto-plastic analysis of residual stresses on different scales during cooling of hot forming parts [PDF]
In current research, more and more attention is paid to the understanding of residual stress states as well as the application of targeted residual stresses to extend e.g. life time or stiffness of a part.

ABSTRACT Maraging steels are high strength alloys used in applications that require both high mechanical strength and toughness. To achieve these properties, one of the heat treatments applied is solution treatment, although it can reduce toughness.

ABSTRACT The fatigue behavior of a metastable austenitic Cr‐Ni‐Cu‐N steel and an austenitic AISI 316L steel was investigated with a focus on the effect of mechanically machined and formed notches, taking into account hardness and residual stress measurements.

ABSTRACT This study explores the use of temperature harmonics to detect intrinsic dissipation during cyclic loading in aluminum alloys. Under sinusoidal loading, the temperature of a solid is modulated by thermomechanical heat sources. The primary source is the thermoelastic effect, which modulates the temperature at the load frequency and twice the ...

ABSTRACT The deformation behavior of carbide‐bearing bainite (CBB) and carbide‐free bainite (CFB) under various loading conditions is investigated. Retained austenite (RA) in CFB enhances strength and ductility only under uniaxial tension through gradual strain‐induced martensitic transformation, yet deteriorates impact toughness and fatigue crack ...

Abstract Results of microanalysis study of NWA 869 meteorite, an ordinary chondrite, where silicates, Fe‐Ni alloys, and troilite are major constituents, are reported. The presented study of microtextures in metallic and sulfide grains provides information on processes occurring from the asteroid's accretion, through the impacts until cooling.

4D Printing of Composite Thermoplastic Elastomers for Super‐Stretchable Soft Artificial Muscles
ABSTRACT This study explores the development of soft, super‐stretchable artificial muscles by 4D printing of composite thermoplastic elastomers. A propylene‐based elastomer, combined with carbon black (CB) nanoparticles, is utilized to develop nanocomposite elastomers with enhanced mechanical properties.
