In the direct hot forming process, a blank is heated up in a furnace, transferred to the press and subsequently formed and quenched in the closed mold [1] (Fig. 3.1). First the sheet is uncoiled and cut according to the shape of the product, then the blank is transferred to a continuous furnace, in which it is heated and fully austenitized.

Tube forming is used to manufacture hollow geometries, otherwise would be stamped and welded. Automotive components could be produced by simply bending and preforming of tubular blanks; or by tube hydroforming (THF). Until recently, THF was limited to aluminum alloys and steels up to 1000 MPa tensile strength.

Hot formed steel is the most successful method in the last few years to reduce weight, save cost and increase safety in the automotive industry. It is still gaining importance for automotive body parts because of its advantageous material properties. Especially its high strength of about 1500MPa makes it possible to manufacture structural parts like B ...

Hot forming of dolomite briquettes
Ceramics International, 1980Abstract Results of experiments to study the production of dolomite clinker having a density close to the theoretical density of pure sintered dolomite are discussed. Density values are reported for samples obtained by the following process: decarbonization of dolomite, hot briquetting at 300–700°C, firing the semi-product at 1500°C.

This chapter discusses hot-consolidation of ceramic powders with and without additives, and hot working of ceramic bodies. Hot consolidation (e.g., by hot pressing) of powders without sintering additives is shown to generally produce the finest grain sizes.

Tribology of hot metal forming
Tribology International, 1998Many aspects of the tribology of hot metal forming are poorly understood. This leads to difficulties when modelling the forming operations to develop process improvements. It also handicaps the development of new tool materials, since the operating conditions with which they will have to cope are not fully described.
