Softening of hot formed steel

ICALEO 2015: 34th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2015
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 Process

2012
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.

Hot Tube Forming

2018
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.

Failures Related to Hot Forming Processes

2021
Abstract The primary purpose of this article is to describe general root causes of failure that are associated with wrought metals and metalworking. This includes a brief review of the discontinuities or imperfections that may be common sources of failure-inducing defects in the bulk working of wrought products. The article addresses the
