Inhomogeneity of Room‐Temperature Elastocaloric Effects in NiTi Alloys Fabricated by Laser Powder Bed Fusion

Rare Metals, EarlyView.
ABSTRACT NiTi shape memory alloys are among the most promising solid‐state refrigeration materials. In recent years, additive manufacturing methods for producing difficult‐to‐machine NiTi alloys have gained increasing attention from researchers. This work successfully produces NiTi alloys with good superelasticity at room temperature via laser powder ...

Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

Rare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Time-resolved imaging of electron beam powder bed fusion using an X-ray microscope optimized for white beam radiation. [PDF]

J Synchrotron Radiat
A high‐speed X‐ray microscope design optimized for white beam synchrotron radiation enables real‐time in situ imaging of crack dynamics during electron beam powder bed fusion (PBF‐EB) of high‐Z materials. With high temporal resolution and 10 µm spatial resolution, the system reveals previously unobservable crack evolution behavior in Ni‐based ...

On the Damage Tolerance of Diffusion Bonded Titanium–Aluminum Phase Biomimetic Composites

Rare Metals, EarlyView.
ABSTRACT The biomimetic design principles of natural structures involve the strategic integration of stiff and compliant phases to synergistically enhance strength and toughness. Its evolutionary refined natural armor, characterized by a specialized microarchitecture, enables superior damage tolerance.
