  • In the last decades, the Shape Memory Alloys, with their peculiar thermo-mechanical properties, high corrosion and extraordinary fatigue resistance, have become more popular in research and engineering applications. This book contains a number of relevant international contributions related to their properties, constitutive models and numerical simulation, medical and civil engineering applications, as well as aspects related to their processing.

  • Since 1970, optical fiber and optical communication technologies have been rapidly developing, causing a technology revolution in the communication industries. Due to much lower attenuation and interference, optical fiber has many advantages over existing copper wire in long-distance and high-demand applications. The revolution in communication industries also significantly reduces the prices of optical components and stimulates the development of optical fiber sensors.

  • The casting process represents the shortest route from the basic material, the alloyed melt, to the casting ready to be installed with optimized multiple functions. In contrast to this unique advantage exists the problem of the difficult control and diagnosis of the casting parameters which are responsible for the quality and the functionality of the casting. Only the melting parameters, chemical alloy composition and pouring temperature which can be set by inoculant or alloy wires and the heating capacity of the furnace before the casting are exceptions....

  • Not all materials can be etched in an easy and cheap way. Especially, noble metals or tantalum are stable against most of these corrosive structuring methods. Hence, precision machining may be used to generate microstructures from these metals as well as from standard metal alloys such as stainless steel or hastelloy. Depending on the material, precision machining can be performed by spark erosion (wire spark erosion and countersunk spark erosion), laser machining or mechanical precision machining.
