EFFECT OF INTERRUPTED BORIDING ON MICROSTRUCTURE AND MECHANICAL PROPERTIES OF 16MnCr5 STEELS

open access: yes, 2018
The microstructure, microhardness and tensile properties of continuously borided and interrupted borided 16MnCr5 steel were compared. In the continuous process, boriding was carried out continuously at 1273[Formula: see text]K for 16[Formula: see text]h.

Chemical Removal of Al From Layered Mn2AlB2: Toward 2D‐MBene and Its Application to MgH2 Hydrogen Storage

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Two‐dimensional Mn‐based MBenes remain challenging to synthesize due to structural instability during etching. Herein, Mn2AlB2 was employed as a precursor to systematically investigate Al removal via HF, NaOH, and a gas–solid route using PVDF‐derived HF.

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

The effect of boron-pack refreshment on the boriding of mild steel by the spark plasma sintering (SPS) process

open access: yes, 2007
Mild steel samples were borided with and without boron pack refreshment using the spark plasma sintering (SPS) process. Results show that the borided samples with boron pack refreshment developed a thicker boride layer compared to that without boron pack

Ultralow‐Ru‐Activated Amorphous NiCoFe Medium‐Entropy Boride for Overall Water Splitting in a Proton‐Exchange‐Membrane Electrolyzer

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Platinum‐free electrocatalysts that combine high activity for the hydrogen evolution reaction (HER) with the stability required for proton‐exchange‐membrane (PEM) water electrolysis remain a central challenge for scalable green‐hydrogen production.
