The wear behavior of three laser clad high speed steel (HSS) alloys and one conventional spun cast HSS alloy was investigated by using a pin on disc tribometer at 25 °C and 500 °C. The wear mechanism was found to be the combined effect of abrasive,

This work deals with the qualification of a variety of steels for their shaping by the thixoforging process. This technology requires setting up a globular microstructure inside the material during reheating to a temperature between the solidus and l

Up to now, no technology exists for producing as-cast thixotropic steel at the industrial or pilot level. The existing processes need to reheat a billet that has been previously cast and wrought on separate equipment. The new processing route, we are

The results observed during ferritic rolling campaigns have highlighted a significant improvement of the behaviour of rolls. This improvement concerns the roll wear, the roughness and the roll surface evolution, as well as the friction coefficient, f
