Abstract: A welded steel part with a very high mechanical strength is provided. The welded steel part is obtained by heating followed by hot forming, then cooling of at least one welded blank obtained by butt welding of at least one first and one second sheet. The at least one first and second sheets including, at least in part, a steel substrate and a pre-coating which includes an intermetallic alloy layer in contact with the steel substrate, topped by a metal alloy layer of aluminum or aluminum-based alloy. A method for the fabrication of a welded steel part and the fabrication of structural or safety parts for automotive vehicles are also provided.

Abstract: Disclosed are methods of processing Chinese kaolin involving providing Chinese kaolin having a desired powder size, delaminating the Chinese kaolin, pulverizing the delaminated Chinese kaolin at least two times, and heating the at least twice pulverized Chinese kaolin. Also disclosed are systems for automated processing of Chinese kaolin containing a pulverizer for pulverizing Chinese kaolin, a tester for testing and generating data of at least one parameter of the Chinese kaolin or at least one parameter of the pulverizer, a controller, operatively coupled to the pulverizer and the tester, for controlling operation of the pulverizer based on data received from the tester.
