Boron Grain Refinement: Part One

Grain refinement is an established technique which basically reduces the grain size of the material with the direct intention to improve its finished properties or characteristics.
The addition of boron specifically in aluminum castings, which are well known for their poor mechanical properties, can improve these characteristics to expand the potential use of the castings to a multitude of other applications. Continue reading

Expert Furnace System Optimization Process (EFSOP)

In typical EAF systems around 45% of input energy is lost through slag or off gas, the latter representing 70% of the complete loss of input energy. The expert furnace system optimization process attempts to tackle this issue by allowing a real time assessment of the energy lost through off gas and to allow plants to react quickly and therefore keep this loss to a minimum.

The Continuous Rheoconversion Process

The Continuous Rheoconversion Process (CRP) is designed to be flexible allowing both thixocasting and rheocasting to be achieved by mixing two melts together at near liquidus temperatures to achieve smaller grain sizes and more globular structures. Key advantages of the CRP include continuous conversion of liquid to slurry, can be used with different alloys, benefits in simplified re-cycling. Continue reading

Boriding Surface Treatments

Boriding is an established surface treatment process which helps tackle the common issue of extending the general life of moving bearing applications and especially in dusty, corrosive environments. There are several advantages of the boriding surface treatment process including a prolonged hardness at high temperatures, flexibility in its applications with different material types and more.

Low Frequency Electromagnetic Casting of Al Alloys

In the Low Frequency Electromagnetic Casting process the mold is surrounded by a coil powered by an alternating current to endue an electromagnetic field. One of the biggest advantages of using the LFEC process in comparison to conventional casting processes is a distinct improvement in the microstructure with LFEC ingots producing a very fine equiaxed grain structure.
