From the engineering point of view, SiC hot-wall epitaxy is a very important process in SiC semiconductor processes.
The requirements for the epitaxial process strongly depend on the devices, so there are many investigations from fundamental to engineering levels.
Design of Engineering Epitaxial Reactor.
From the engineering points of view, it is necessary to keep good uniformity of both epitaxial layer thickness and doping concentration, inside a wafer and between wafers.
In the experiment, there are lots of investigations that try to understand the fundamental processes and also try to develop engineering reactors.

Numerical Studies on Friction Stir Welding of Lightweight Materials Xiaocong He Innovative Manufacturing Research Centre，Faculty of Mechanical and Electrical Engineering, Kunming University of Science and Technology, Kunming，650500, P.
Friction stir welding (FSW) is a relatively new solid-state fastening method which is suitable for joining advanced lightweight metal sheets that are hard to weld.
An advanced FE model was presented by Hamilton et al. [16] for simulating FSW process.

The basic idea was to establish a periodical international forum presenting multiscale approaches in fati gue and fracture of materials.
Therefore, respective sections focused on atomistic models, models based on crystal defects, nu meri cal and statistical models based on continuum mechanics, advanced experimental methods and relationships between structure and mechani cal prope11ies appeared during the MSMF-2 conference in 1998.
Nearly 150 scientists from 2 1 countries all over the world presented a vari ety of multiscale approaches in modeling and testing deformati on and fracture processes in engineering materials.
It is my pleasure to thank the editorial board of the journal Materi als Science Forum fo r the readiness to publish this vol ume devoted to MSMF-4.

The forum took place in Gifu, Japan, 24 years ago for the first time.
The overarching goal of this conference was to provide an international forum for the representation and discussion of research results in lubrication, friction, wear, and development of the tribological systems pertaining to manufacturing processes.
Three plenary lectures were given covering: (a) Advances in tribological coatings for superlubricity and ultra-high wear resistance, (b) An integrated experimental and molecular modelling approach to investigate tribological mechanics in hot rolling of metal, and (c) Overview of metal forming research in Indian Academia.
We would also like to extend our gratitude to authors who were devoted to advancing the understanding of tribological phenomena pertaining to a broad range of manufacturing processes.
These proceedings provide a record of efforts by international researchers working on tribology for manufacturing systems, and we hope that the presented articles will be helpful for you in searching for innovative engineering solutions.
