In light of emission reduction and weight saving in transport applications, Mg parts gain alot attention due to their good specific mechanical properties and their low mass. While casting is themain process for manufacturing Mg parts for automotive applications, forged parts show some majorbenefits like superior mechanical properties and absence of porosity. In this work a comparison ofclosed die forged parts made from different Mg-alloys has been carried out. The materials used in thewarm forging process were AZ31 and various Mg-Al-Zn-Ca-Y type (AZXW) alloys. Ca additions areknown to improve the oxidation behaviour and the formability of magnesium alloys, while yttrium isused to enhance the flammability resistance of forged parts. The forgeability, mechanical propertiesand microstructure are analyzed and compared in the present paper.

Thermal Stability Of

Thin nanostructured Ti-B-N-based films are known for their excellent mechanical properties and their stability at high temperature in oxidizing atmosphere. In the present work, nanostructured Ti-Al-Si-B-N and Ti-Cr-B-N coatings deposited on AISI 304 stainless steel by ion implantation have been characterized. To evaluate the oxidation resistance and thermal stability, the coatings were annealed at 900°C in vacuum and in air for 4 hours. The mechanical properties, phase composition and micro-structure of as-deposited and annealed coatings were addressed. The coatings showed a complex multilayered structure and a substantial change of their mechanical properties, due to the new structure and to the phases formed after air annealing.
