Electrical properties of magnesium titanate ceramics post-sintered by hot isostatic pressing [PDF]

Science of Sintering, 2017
Post-sintering of magnesium titanate ceramics by hot isostatic pressing (HIP) in an oxygen-free atmosphere significantly alters various electrical properties of the product. In particular, the sintered material becomes a semiconductor.

A Data‐Centric Approach to Quantifying the Forward and Inverse Relationship Between Laser Powder Bed Fusion Process Parameters and as‐Built Surface Roughness of IN718 Parts

Advanced Intelligent Systems, EarlyView.
This study introduces the first inverse machine learning model to predict laser powder bed fusion process parameters for targeted surface roughness of Inconel 718 parts. Unlike prior approaches, it incorporates spatial surface characteristics for improved accuracy.

Numerical Simulations of Very Low Velocity Impacts and Ignition of an Explosive Confined by a Thin Case

Propellants, Explosives, Pyrotechnics, EarlyView.
A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.

In Situ Uniform Lithium Enrichment for Dense, High‐Performance LLZO Solid Electrolytes

Rare Metals, EarlyView.
ABSTRACT A major challenge in garnet‐type Li7La3Zr2O12 (LLZO) system all‐solid‐state electrolytes is the high porosity that typically remains after sintering, which compromises ionic conductivity and degrades battery cycling performance. To address this, we propose an innovative strategy to achieve uniform lithium enrichment on the surface of ...

Investigation of Microscopic Nonmetallic Inclusions in Powder Metallurgical High‐Speed Steels

steel research international, EarlyView.
Methods for inclusion analysis are evaluated for suitability. Various powder metallurgical steels in different processing states are characterized. SEM/EDS data are further analyzed using analytical and statistical approaches. A thermodynamic method for determining inclusion phase composition is tested.

Numerical simulation and verification of hot isostatic pressing densification process of W-Cu powder

Materials Research Express, 2022
Based on finite element method (FEM) and the plasticity theory, a numerical model is built to simulate the hot isostatic pressing (HIP) process of W-Cu powders, and the densification law of the compact in the process is analysed.

Tuning the microstructural and micro‐/nanomechanical properties of silicon nitride–carbon nanotube composites by powder oxidation

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Microstructure showing hexagonal α‐Si3N4 (green arrows) and CNTs distributed between beta‐Si3N4 (yellow arrows) and the oxidation impact to elastic moduli. Abstract The effects of the oxidation on the micro/nanohardness, density, and microstructure of the silicon nitride–carbon nanotube (Si3N4–CNT) composite were investigated.

Synthesis and thermal properties of dense Si─Al─C─N‐based polymer‐derived ceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract In the present study, aluminum‐modified preceramic silicon polymers were synthesized via chemical modification of a commercially available organopolysilazane using an aluminum amido complex. The incorporation of aluminum into the polymer structure and its effect on ceramization behavior and processability as well as the thermal and mechanical ...

Development of super-solidus heat treatments for the second-generation single-crystal Ni-based superalloy ERBO/1: Experiments and 1D kinetic simulations

Journal of Materials Research and Technology
Super-solidus hot isostatic pressing heat treatments are particularly beneficial for single-crystal superalloys, which exhibit highly segregated microstructures after casting, because they not only contribute to reducing chemical heterogeneities in a ...
