PREFACE This volume contains some selected papers from the 2012 International Conference on Advanced Materials Engineering and Technology (ICAMET 2012) which is to be held in Penang, Malaysia during November 28-30, 2012, and is organized by Centre of Excellence Geopolymer & Green Technology (CEGeoGTech), School of Materials Engineering, Universiti Malaysia Perlis.
The conference aims to provide a high level international forum for researchers, engineers and scientists to present their new advances and research results in the field of advanced materials engineering and technology.
This volume covered all the aspects of advanced materials engineering and technology, particularly of advanced characterization, biomaterials, biotechnology and life sciences, building materials, coating and surface engineering, composite and polymer materials, optical and photonic materials and any other related topics.
The editors hope that this volume will provide the reader a broad overview of the latest advances in the field of advanced materials engineering and technology, and that will be as valuable reference source for further research.

From 1949 to 1990, the average percentage of engineering graduates in all graduates is 17.9%, while the average percentage of that in the whole China is above 30%.
So they hope that there are more students graduate from the majors of engineering and science.
And this is compliant with the 2013 Industry Plan of Fujian province which said that Fujian province should pay more attention to the development of advanced manufacture and take it as center of Fujian’s economy.
And the development of advanced manufacture needs lots of engineering and science talent.[5]So the increase of enrollment of engineering students is actually vital for the economy development of Fujian province and will promote it develop in a higher efficient and healthier way.
Forum of Higher Education (2).

Every two years SheMet Conference is an interdisciplinary and international forum, encouraging the close cooperation between material scientists, manufacturing and computer engineers and promoting the diffusion of research results and technology transfer in all the areas of Sheet Metal Processing and Characterization.
Nevertheless other more conventional areas, such as bending or stamping, are not neglected: on the contrary dedicated sessions are focused on the most advanced research results in these areas.

On purpose of analyzing the relationships among heat treatment process, microstructural features and fracture toughness, 7085 aluminum alloy are chosen to be investigated for its widely used on the structural parts of advanced aircrafts[5,20].

PREFACE Mass transport and related kinetic processes in silicate and oxide systems (including minerals, glasses, composites, melts and liquids) are of considerable interest and importance to fields as diverse as Ceramics, Chemistry, the Earth Sciences, Engineering, Materials Science and Physics.
With significant advances in instrumentation, experimental methods, and computer modelling techniques during the last twenty years rapid progress has been made in our understanding of these systems.
To try and breach the artificial subject boundaries and provide a forum for all workers interested in silicates and oxides a conference was held on KINETICS AND MASS TRANSPORT IN SILICATE AND OXIDE SYSTEM in London in September, 1984.
