A fabrication method for a press hardened part is provided. A sheet or a steel substrate blank for heat treatment is provided. A pre-coating is applied. The pre-coating has at least one layer of aluminum or aluminum alloy in contact with the steel substrate on at least one of the principal faces of the sheet or blank. Then a polymerized layer is deposited on the pre-coating. The polymerized layer has a thickness between 2 and 30 m. The polymerized layer does not contain silicon, has a nitrogen content of less than 1% by weight and carbon pigments in a quantity between 3 and 30% by weight. The blank or the sheet is heated to obtain an interdiffusion between the steel substrate and the pre-coating and to give the steel a partly or totally austenitic structure. Then the blank or the sheet is hot stamped to obtain a part. The part is cooled by holding the part in a stamping tool so that the microstructure of the steel substrate includes, at least in a portion of the part, martensite or bainite.

A process for producing an ethylene-based polymer comprises polymerizing, by the presence of at least one free-radical initiator and using a high pressure tubular polymerization process, a reaction mixture containing ethylene and at least one CTA system comprising one or more CTA components to produce the ethylene-based polymer. The free-radical initiator is dissolved in a solvent comprising a saturated hydrocarbon to form an initiator solution which is added to the polymerization using an initiator feed line to an initiator injection pump. At least 50 wt % of the solvent has i) a dry point of less than or equal to 160 C. and ii) an initial boiling point of greater than or equal to 100 C. The polymerization process has a ratio of inlet pressure to first peak temperature of less than or equal to 9 Bar/ C. At least one CTA make-up stream is fed into the polymerization process, wherein less than or equal to 30 wt % of the at least one CTA make-up stream comprises one or more saturated hydrocarbon CTA(s) with a maximum carbon atom number of 6 per molecule.

A method of making a homogeneous mixture of polyolefin solids and carbon solids without melting the polyolefin solids during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the carbon solids for a period of time sufficient to substantially intermix the polyolefin solids and the carbon solids together while maintaining temperature of the heterogeneous mixture below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.
