Static recrystallization of shocked calcite in Ries impact breccias

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia

EFFECTS OF POST PROCESSES ON THE MECHANICAL PROPERTIES OF TI-6AL-4V TITANIUM ALLOY BY SELECTIVE LASER MELTING

open access: yesJixie qiangdu, 2019
Ti-6 Al-4 V titanium alloy specimens were built using selective laser melting. Some specimens were heat treated and some were hot-isostatically pressed. Half of these specimens in three conditions were polished.

Hot Isostatic Pressing of Beryllium Oxide

open access: yesJournal of the Ceramic Association, Japan, 1973
高圧ガス圧縮装置を用いて, 温度1000°-1400℃, 圧力2kbarの条件下で酸化ベリリウムの静水圧焼結を行なった. この種の実験では, 従来, 圧力媒体として, 高融点金属が用いられてきたが, 著者らは, その代りにガラスを使用することにより, 非常に良好な結果を得た.本実験において, その緻密化は, 塑性流動によって非常に速く進行するという結論が得られた. これらの焼結体は低い温度で, しかも比較的短時間内に, すべて理論密度の値に達しており, 粒子の異常成長は全く認められなかった. これらのことから, ガラスを圧力媒体とする静水圧焼結は, 均一な微粒子から成る緻密な焼結体が得られるものと結論できる.

Ablation Properties of HfC–SiC–WC Ultra‐High Temperature Ceramics Produced by Pressureless Sintering

open access: yesInternational Journal of Ceramic Engineering &Science, Volume 8, Issue 4, July 2026.
Schematic diagram highlighting the processes that occur during ablation testing of HfC–SiC and HfC–SiC–WC. ABSTRACT HfC–SiC is one of the leading thermal insulation ceramics that has the potential to perform well under high thermomechanical loads. In this study, we explore the use of pressureless sintering to produce this material at relatively low ...
