Densification of powder metallurgy billets by a roll consolidation technique [PDF]
, 1973 Container design is used to convert partially densified powder metallurgy compacts into fully densified slabs in one processing step. Technique improves product yield, lowers costs and yields great flexibility in process scale-up. Technique is applicable

Advanced Engineering Materials, EarlyView.Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

Advanced Engineering Materials, EarlyView.This study compares the mechanical properties of Inconel 718 with two newly developed compositionally complex alloys (CCAs). Inco‐like‐H alloy demonstrates significantly improved wear resistance, surface finish, and hardness, notably at high temperatures. This CCA requires no heat treatment and is well suited for additive manufacturing. Its performance

Metallurgy in the Early Steppes [PDF]
Artibus Asiae, 1970 In Europe copper appeared in the middle of the third millennium B.c. in the framework of a developed technology in two marginal regions, in Spain and Portugal and on the shores of the Aegean. From both centers ready-made implements were exported over large areas mostly by sea trade.

Micromechanical Insights into Sinter‐Based Additively Manufactured NiTi with Nb as a Sintering Aid
Advanced Engineering Materials, EarlyView.This study investigates the microstructural and micromechanical behavior of NiTiNb made through filament‐based materials extrusion via chemically correlated nanoindentation. B19' remnants from the original powder lead to Nb gradients within NiTiNb grains due to the short sintering times required in liquid‐phase sintering.
