Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, Volume 97, Issue 10, Page 5069-5078, October 2026.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

Influence of austenitizing, quenching, and tempering on the hardness and corrosion resistance in martensitic stainless steel EN 1.4116

Journal of Materials Research and Technology
Martensitic stainless steels (MSS) are a vital class of steel used in various sectors, including aerospace, petrochemicals, and cutlery, due to their excellent properties, such as high mechanical strength and corrosion resistance. Research has shown that

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Effect of carbide characteristics on abrasive wear behavior during knife honing: A comparative study of martensitic stainless steel and spring steel

Journal of Materials Research and Technology
The resharpenability of knife steels is crucial for extending kitchen knife service life, yet the underlying mechanisms governing edge reconstruction during sharpening remain poorly understood.

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Relation microstructure-propriétés mécaniques d'un acier martensitique inoxydable

MATEC Web of Conferences, 2013
The relationship between microstructure and mechanical properties of MaX (1.4006) martensitic stainless steel has been studied. Optical microscopy was used to characterize the microstructure and the volume fraction of retained ferrite was measured by ...

Functionally Graded Martensitic Stainless Steel

IOSR Journal of Mechanical and Civil Engineering, 2014
Functionally graded materials (FGM) are defined as an anisotropic material whose physical properties vary continuously throughout the volume, either randomly or strategically, to achieve desired characteristics or functionality. The aim of this project is to perform a modal analysis to determine the natural frequencies and mode shapes of a FGM using ...

Multiscale Experimental Techniques for Evaluating Hydrogen Resistance in Structural Alloys for Energy Systems

Advanced Energy and Sustainability Research, Volume 7, Issue 9, September 2026.
Hydrogen embrittlement proceeds through three distinct mechanisms: localized plasticity, decohesion, and hydride formation, each demanding different experimental evidence across atomic to macroscopic scales. This review maps experimental techniques to their operative mechanism and proposes a multiscale, mechanism‐informed framework linking technique ...

Corrosion fatigue of a superduplex stainless steel weldment [PDF]

, 2004
Superduplex stainless steels have superior mechanical and corrosion properties compared to austenitic stainless steels such as the grade 300 series. This is a result of a microstructure consisting of roughly equal percentages of austenite (y) and ferrite
