Microstructural, Magnetic, and Tribological Optimization of Nano‐ZrO2 Reinforced Magnesium Matrix Composites Fabricated via Powder Metallurgy

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
Magnesium–ZrO2 nanocomposites fabricated via powder metallurgy exhibited enhanced density, magnetic saturation (up to 14 emu/g), and wear resistance. Uniform nanoparticle dispersion improved bonding and reduced delamination, demonstrating strong potential for lightweight, multifunctional applications in aerospace and automotive engineering.

Processing and properties of calcium phosphates bioceramics by hot isostatic pressing

open access: yesMATEC Web of Conferences, 2013
Stoichiometric β-tricalcium phosphate (β-TCP), hydroxyapatite (HA) and biphasic calcium phosphate (TCP/HA 60/40 %wt, BCP40) powders were synthesized by chemical precipitation of aqueous solutions of diammonium phosphate and calcium nitrate.

Progressively Fenitised Schist and Carbonatitic Clasts From a Metasomatic Aureole Beneath the Alkalic Dunedin Volcano, Otago, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Clasts of albite‐porphyroblastic quartzofeldspathic schist, derived from the Otago Schist basement, occur within the Port Chalmers Breccia, a diatreme at the centre of the Dunedin stratovolcano, New Zealand. Schists have undergone varying degrees of replacement reactions (at temperatures of 300° to >500°C) producing hornfelses, with Ca‐ and K‐enriched ...

Generation of Channelized Mantle Flow Beyond the Rift Zone Accelerated by Thermal Heterogeneity and Rift Propagation

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Rifting is a tectonic process that leads to extensive magmatic activity, continental breakup, and the formation of new oceanic crust. The interplay between rifting and dynamic mantle flow driven by thermal heterogeneity in the mantle along the rift‐axis can influence magmatism and deformation beyond the rift zone.

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Preparation and mechanical properties influencing of Ti2AlNb powder alloy

open access: yesCailiao gongcheng
The hot isostatic pressing process is a usual powder Ti2AlNb alloy preparation method to deeply study the influence of factors such as the powder-making process on the properties of Ti2AlNb powder alloy.Ti2AlNb pre-alloyed powders are prepared by plasma ...

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Arc Heat Flow and Magmatic Heat Budgets

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Effect of Hot Isostatic Pressing on Mechanical Properties of K417G Nickel-Based Superalloy

open access: yesCrystals
The cast nickel-based superalloy K417G exhibits excellent high-temperature strength, but non-equilibrium solidification during casting can cause defects such as irreparable interdendritic microporosity, which significantly degrades its fatigue and creep ...
