Charles Albert Keller, industriel électrométallurgiste installé à Livet (isère), prit en 1908 un brevet sur la « Fonte Synthétique ». Si son savoir-faire en matière de fours adaptés à la fusion des métaux fut d’un grand secours, cette fonte de moulage au silicium, fabriquée grâce à la collecte et au recyclage de tournures d’acier en provenance de l’industrie, et notamment de l’industrie de guerre, fut extrêmement précieuse. Utilisée pour la fabrication des obus de gros calibre (220 et 400 mm) qui alimentaient le front, elle contribua ainsi à la victoireRead more

R&D 100 Award Winner: Computationally Optimized Homogenization Heat Treatment Process (US)

Share on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInPin on PinterestEmail this to someonePrint this page

Conventional homogenization processes require much experimentation. This usually entails numerous samples, substantial furnace time and associated energy, and additional lab time to physically evaluate the extent of homogenization. The novel method utilizes thermodynamic simulation to determine the specific distribution/arrangement (i.e., the microsegregation) of alloying elements in the cast alloy. This is accomplished using the Scheil module of Thermo-Calc software. The determined microsegregation profiles are read into DICTRA kinetic modeling software to simulate elemental diffusion during homogenization heat treatment. 

Alloys are combinations of two or more elements. During solidification of any alloy, the elements segregate unevenly. This chemical segregation is unavoidable and results in non-uniform regions that negatively impact an alloy’s mechanical and physical properties. Redistribution of the alloying elements is necessary to achieve optimal performance for the desired application of an alloy. The computational approach to homogenization uses basic diffusion kinetics based on the chemical diffusion coefficient of each element toRead more

Self-driving cars that do not crash could reduce the need for steel products (US)

TOKYO — Constant technological innovation is shaking up traditional markets and forcing established manufacturers to adapt or die. Two big names caught in such turbulence are Japan’s Kobe Steel and Hitachi Metals, whose growth engines are at risk of becoming outdated.  Kobe Steel will close the blast furnace at its Kobe Works in Hyogo Prefecture in October, leaving the company with only two blast furnaces — at its Kakogawa Works, also in Hyogo. Blast furnaces make iron by burning iron ore and coal. Kobe Steel Chairman and President Hiroya Kawasaki has been gazing into the crystal ball, and what he sees does not bode well for his mainline business. In 10 years, for example, the emergence of self-driving cars that do not crash could change the industry landscape by reducing the need for steel products. After all, if cars do not crash, softer, lighter materials would suffice where steel was once needed.

“I’m not sure if iron made at blast furnaces will still be used 100 years from now,”

The furnace has three interchangeable crucibles with the capacity for melting 250kg, 500kg and 1000kg of metal, which give it the versatility to produce components with a finished weight ranging upwards from 60kg. A molten mass in excess of 1000kg is required to make a 500kg titanium casting and only a handful of furnaces exist globally that are capable of casting near net shape aerospace components of this size.

A castings facility capable of producing some of the biggest titanium aerospace components in the world is now operational at the University of Sheffield Advanced Manufacturing Research Centre (AMRC). Construction of the furnace for the AMRC Castings Group was completed last year and in the past few weeks the first tests or ‘hot commissioning’ as it is known, have been completed successfully. The furnace has three interchangeable crucibles Read more

Special Steel Inspired by Bone is More Resistant to Cracking (US)

Share on FacebookShare on Google+Tweet about this on TwitterShare on LinkedInPin on PinterestEmail this to someonePrint this page


Load cycling of metal components leads to fatigue and ultimately failure through the propagation of cracks. Koyama et al. took inspiration from bone to develop a steel with a laminated substructure that arrests cracks. The resulting hierarchical material has much better fatigue resistance properties than other iron alloys. The strategy need not be limited to steel; other metal alloys should also benefit from this type of microstructural engineering.

Getting close to the bone is sometimes exactly the right strategy. Mimicking the crack-resistant properties of bone has delivered two new types of steel, which could improve safety in construction and transport applications. Steel is ubiquitous: we use it in everything from cars and aircraft to power plants and bridges. It’s affordable and its alloys can be easily tailored for specific applications. But it is also vulnerable Read more

Keystone builder TransCanada will be allowed to skirt an executive order calling for US steel to be used in new pipelines, repairs, or retrofits. Does the move herald a broader evolution for Trump’s ‘America First’ stance?

From the start of President Trump’s election campaign, two aspects of his political identity – the businessman and the populist – have dueled for dominance. At least in the case of the Keystone XL pipeline, the businessman appears to be winning out. Speaking to reporters onboard Air Force One on Friday, White House spokeswoman Sarah Huckabee Sanders said that the pipeline,

“The value of a pipeline is that we have a pipeline that can be used. Which steel it is made from is an entirely subsidiary question,  and if American steel is best to use then use that, if not American is better then use that instead.
