Studies of material deposition during boronization using quartz crystal microbalance in EAST

Nuclear Materials and Energy
Boronization is a widely employed technique for controlling fuel recycling and suppressing impurities. It is expected to be a routine wall conditioning method in the fully tungsten (W) wall configuration of the International Thermonuclear Experimental ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Enhancing energy confinement through controlled boronization in VEST ohmic discharges

Nuclear Fusion
An enhanced energy confinement regime with minimized radiative losses has been observed by controlled boronization (BZn) in the Versatile Experimental Spherical Torus (VEST), achieving ${H_{89 - {\text{P}}}}{ }\sim { }2.0{\text{ }}$ without any external ...

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Study on the influence of boronization on the first mirror unit in EAST

Nuclear Materials and Energy
The new ITER baseline adopts full-tungsten (W) plasma-facing components (PFCs). Boronization is employed as the primary wall-conditioning technique to suppress oxygen (O) impurities during the initial operation stage. To evaluate its impact on diagnostic
