The automotive industry requirements for vehicle weight reduction,
weight containment, improved part functionality and passenger
safety have resulted in the increased use of steel grades with a
fully martensitic microstructure. These steel grades are essential
to improve the anti-intrusion resistance of automotive body parts
and the related passenger safety during car collisions. Standard
advanced high strength steel (AHSS) grades are notoriously
difficult to be formed by cold stamping; they are characterized by
elastic springback, poor stretch flangeability and low hole
expansion ratios. Hot stamping has therefore received much
attention recently as an alternative technology to produce AHSS
automotive parts.In this book, selected articles from the Fourth
International Conference on Advanced High Strength Steel and Press
Hardening held on August 20-22th, 2018 in Hefei, China, are
compiled. It focuses on AHSS for the development of press hardening
of high performance sheet metal for lightweight vehicle, advanced
digital manufacturing technology, as well as the physical
metallurgy principles of the hot stamping process.Aiming at the
process design and industrial application for hot stamping of press
hardened steel and high strength aluminium alloy sheet, the effect
of temperature and strain rate on the formability and mechanical
properties of the products is discussed. In addition, more
practical cases are provided concerning accurate modelling and
multi-physics coupling simulation of the hot stamping process.
Furthermore, the influence of tool design on forming process, more
precise process control strategies to increase production
efficiency, and the improvement of hot stamping equipment by
advanced design methods will also be presented.
This proceedings brings together seventy seven selected papers
presented at the 3rd International Conference on Advanced High
Strength Steel and Press Hardening (ICHSU2016), which was held in
XiaEURO (TM)an, China, during August 25-27, 2016.In this rapid
growing market in advanced high strength steel and press hardening,
in particularly demand from automotive industry and sustainability
community to develop light-weight materials for Body in white or
BIW, has motivated us to organize ICHSU2016, soon after the
successful conclusion of our ICHSU2015 last year to encourage
experts all over the world to get together again to exchange note
and ideas as how to move the R&D in press hardening technology
forward in the new era.The purpose of holding ICHSU2016 is to
satisfy the increasingly urgent requirement of reducing the weight
of vehicle structures and increasing passenger safety. This
conference arouses great interests and attentions from domestic and
foreign researchers in hot stamping field, of the articles
accepted, covering almost all the current topics of advanced high
strength steel and press hardening technology, which includes
materials & testing, modeling & simulation, process design,
tribology & tools, equipment and product properties.
This proceedings brings together one hundred and ten selected
papers presented at the 2nd International Conference on Advanced
High Strength Steel and Press Hardening (ICHSU2015), which was held
in Changsha, China, during October 15-18, 2015.To satisfy the
increasingly urgent requirement of reducing the weight of vehicle
structures and increasing passenger safety, ICHSU2015 provided an
excellent international platform for researchers to share their
knowledge and results in theory, methodology and applications of
advanced high strength steel and press hardening technology.This
conference aroused great interests and attentions from domestic and
foreign researchers in hot stamping field. Experts in this field
from Australia, China, Germany and Sweden, contributed to the
collection of research results and developments. The papers cover
almost all the current topics of advanced high strength steel and
press hardening technology.
