Second International Conference on Innovative Materials and Structures Technologies in Metallurgical Engineering, METECH '14 aims at bringing together leading scientists, researchers, scholars and industry actors to exchange and share their experiences and research results about all aspects of smart composite and all other innovative materials, and nanotechnology in engineering, and discuss the practical challenges encountered and the solutions adopted.   Intelligent materials can be defined as materials that sense and react to environmental conditions or stimuli (e.g. mechanical, chemical, electrical, or magnetic signals). In the last decade, a wide range of novel smart materials have been produced for aerospace, transportation, telecommunications, and domestic applications. Furthermore there is increased activity in integrating intelligent materials with nanotechnology to develop novel materials for the applications in biomaterials, sensors, actuators, and textiles. On the other hand hybrid ans composite materials in industry becomes a necessity to control of matters.
