Data-driven study of composition-dependent phase compatibility in NiTi shape memory alloys

Materials & Design
The martensitic transformation in NiTi-based Shape Memory Alloys (SMAs) provides a basis for shape memory effect and superelasticity, thereby enabling applications requiring solid-state actuation and large recoverable shape changes upon mechanical load ...

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

steel research international, EarlyView.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

Influence of Heat Treatment and Scan Rotation on the Microstructure of Hot Work Tool Steel Manufactured using Laser Powder Bed Fusion

steel research international, EarlyView.
The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

TRANSFORMATION BEHAVIOR OF A Ti50Ni47Fe3 ALLOY : II. MARTENSITIC TRANSFORMATION

, 1982
In-situ electron microscopy observations of the martensitic transformation and the martensitic phase in thin foils of a Ti50Ni47Fe3 alloy have been made. The Ms temperature in such thin foils is about -98°C.

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, EarlyView.
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.

MARTENSITIC TRANSFORMATION INDUCED BY TENSILE STRESS PULSES

, 1988
La cinétique de la transformation martensitique induite par un pulse de tension tractive, produit par la reflection d'une onde de choc compressive sur une surface libre, a été etudiée dans un interval de temps d'à peu près une microseconde. Deux alliages

Recycling End‐of‐Life Solid Oxide Cell Interconnect Assemblies into Commercial‐Grade AISI 304 Stainless Steels

steel research international, EarlyView.
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.

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.
