WELDING OF RAILS WITH NEW TECHNOLOGY OF ARC WELDING
Metalurgija, 2013 The paper presents up-to-date achievements in application of a new method of arc welding of various rail profiles, defined as the Consumable Guide Enclosed Arc Welding (CGEAW).The welding process is based on a combination of specially prepared electrode, which core is identical in chemical composition to welded material, or belongs to its class, and ...

Macromolecular Materials and Engineering, EarlyView.This study explores how polypropylene viscosity influences the structure and performance of thermoplastic dynamic vulcanizates made with devulcanized tire rubber. Higher matrix viscosity results in better dispersion of the rubber phase, forming smaller domains and enhancing mechanical properties. The findings support more efficient recycling strategies

steel research international, EarlyView.In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can
