The tribo-characteristics of metal forming at high temperatures have not yet been well
understood due to the complex nature of thermal, microstructural, interaction, and process …

In this study, the high temperature wear behavior of hot forming tool steel grades is
investigated by successive sliding of a pre-alloyed Usibor1500P® strip heated at high …

To improve the performances of new hot stamping processes for automotive industry, as well
as to overcome their numerous drawbacks-such as oxidation, dies wear, severe thermal and …

Press hardening is employed in the automotive industry to produce advanced high-strength
steel components for safety and structural applications. This hot forming process depends …

In the hot stamping process, the friction and wear interaction between the hightemperature
sheet metal and the water-cooled die has a significant impact on the final quality of the …

In the last years, the use of High Strength Steels (HSS) as structural parts in car body-in-
white manufacturing has rapidly increased thanks to their favourable strength-to-weight ratio …

Two alumina coatings are developed to protect tool surface in hot forging: pure γ-alumina
matrix loaded with α-alumina particles and pure γ-alumina matrix loaded with h-BN particles …

Friction losses and wear losses are the main failure reasons in the internal combustion (IC)
engine components ie, cylinder liner and piston. So, it demands lightweight self-lubricating …

One of the key factors determining the lifetime or durability of hot forging tools is their
resistance to wearing. The application of laser technology to prepare a non-smooth unit on …

This thesis summarises the research that I performed during the first part of my Ph. D. studies
at the Division of Machine Elements at Luleå University of Technology. I have to admit that …
