Impact of the Process Atmosphere During Hot Isostatic Pressing on the Near‐Surface Composition of an Additively Manufactured Austenitic High‐Interstitial Steel

Advanced Engineering Materials, EarlyView.
A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

Advanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

A New Ordered Transformation‐Induced Plasticity Enables Exceptional Strength and Ductility in a B2 Medium‐Entropy Alloy

Advanced Science, EarlyView.
A novel B2‐ordered Ti‐Zr‐V‐Al medium‐entropy intermetallic is developed through controlled metastability engineering, which activates an ordered TRIP effect via a new B2→D019‐α2 transformation with a distinctive {0001}α2//{110}B2, <11‐20>α2//<100>B2 orientation relationship. This alloy achieves an elongation of ∼7%, a strength of ∼1.1 GPa, and superior
