High-Entropy Alloy-Coated Nanolattice Structures (US)

In this work microfabricated three-dimensional polymeric nanolattices were conformably coated with a thin layer of high-entropy alloy (CoCrFeNiAl0.3) film via physical vapor deposition.

Periodic three-dimensional (3D) structures with nanoscale constituents, often referred to as ‘‘nanolattices’’, are of extensive interest recently due to the rapid advances in additive manufacturing (such as 3D printing) at the micro/nano-scale. They have great potentials to be used for a variety of engineering applications, such as light-weight structural materials, functional frameworks for sustainable energy, scaffolds for cells culturing and drug Continue reading

New ASTM Standard Concerns Alloy Useful in Stents, Implants (US)

A new ASTM International standard covers a high- strength alloy that could be used for cardiovascular stents as well as trauma, spinal, and face-related surgical implants. “This powder-metallurgy alloy has a good combination of high strength and high ductility when compared to other metallic implant materials,” said ASTM International member John Disegi, a consultant at Advanced Biomaterial Consulting LLC. He noted that this could allow product engineers to “downsize” various existing implants. Technically speaking, the standard is a specification for the chemical, mechanical, andContinue reading

Sigma Clermont se dote d’un centre d’usinage du titane sans équivalent (FR)

Après son exposition au Salon EMO d’Hanovre (Allemagne) du 18 au 23 septembre 2017, les premiers éléments du nouveau centre d’usinage de titane multi-axes Flexia V ont été livrés au début du mois d’octobre à SIGMA Clermont. L’assemblage se poursuivra jusqu’à la fin d’année 2017 pour une mise en service début 2018.

Mécaniciens des matériaux et des structures, roboticiens, informaticiens et spécialistes de la production manufacturière sont d’ores et déjà à l’œuvre sur la plateforme technologique de l’école pour imaginer les solutions de demain. Les industriels sont également associés au projet, notamment Aubert & Duval, qui a inauguré dernièrement à Saint-Georges-de-Mons (Puy-de-Dôme) une usine de recyclage du titane unique en Europe. SIGMA Clermont a également noué un partenariat avec Airbus et Safran. D’autres collaborations sont prévues dans la durée, sachant que l’exploitation de la machine, sa maintenance et la fourniture du support technique sont assurées par l’école.

Cette machine, acquise dans le cadre du projet RoMaPAR+ du CPER (Contrat de plan Etat-Région) 2015, aux caractéristiques exceptionnelles (courses de 2 mètres, puissance de broche de 100 kW), est la premièreContinue reading

SSAB aims to be fossil-free by 2045 (US)

SSAB increases the company ambitions for sustainability and sets new long-term objectives. By 2045 SSAB aims to be totally fossil-free. However, in the mid-term, the most noticeable sustainability impacts will be achieved by our sustainable offering: 10 million tonnes in annual customer CO2 savings by 2025. 

“In many respects we are already a forerunner and we want to retain that position in the future. The sustainability trend is transforming the steel industry and noticeable measures are required to mitigate climate change. Our new objectives are highly ambitious, but we feel certain that we will reach them. Achieving our goals requires greatContinue reading

Electric cars prompt consultants CRU to explore cobalt sulphate (US)

LONDON (Reuters) – Metals consultancy CRU Group wants to create a price mechanism for cobalt sulphate, in response to increasing demand for the compound used in making rechargeable batteries that power electric cars. Prices for cobalt sulphate are often based on those for refined metal published by Metal Bulletin. The London Metal Exchange’s cobalt contract is also for refined metal. But demand for cobalt sulphate is expected to outpaceContinue reading

Welding trials of new Aubert & Duval nickel alloy, AD730® (US)

Introduction

Aubert & Duval designed the new nickel alloy AD730® in response to the need for metals that can function at high temperatures in fields such as aerospace, energy, and the automotive industry.

The industrial environment

The need to enhance the efficiency of aero engines has been the driving force for the development of new materials that combine high tensile strength, resistance to fatigue and creep with the capability to operate in the 700°C/750°C (1292°F/1382°F) temperature range. In the same way, new power generation concepts, aiming at higher
