The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Caddo Ceramic Vessels from the T. M. Sanders Site (41LR2) on the Red River in Lamar County, Texas [PDF]
The T. M. Sanders site (41LR2) is one of the more important ancestral Caddo sites known in East Texas, primarily because of its two earthen mounds and the well-preserved mortuary features of Caddo elite persons buried in Mound No. 1 (the East Mound). The

Lightweight SFRC benefitting from a pre-soaking and internal curing process [PDF]
The presented research program is focused on the design of a structural lightweight fiber-reinforced concrete harnessing an internal curing process. Pre-soaked waste red ceramic fine aggregate and pre-soaked artificial clay expanded coarse aggregate were

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy
An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Ceramic Pipes from Lake Sam Rayburn Caddo Sites, Angelina River Basin, East Texas [PDF]
Ceramic pipes are an important part of the ancestral Caddo material culture in all parts of the Caddo area from as early as ca. A.D. 800, and there are also ceramic pipes known from Woodland period sites in the Caddo area.
