Mechanical stresses upon phase transitions
Mechanical stress studies were carried out on three different groups of functional coatings using a purpose-built system. Functional coatings have become increasingly important in recent years due to their interesting technological applications. In this work three different groups of coatings were …

Physical studies of strained Si/SiGe heterostructures : from virtual substrates to nanodevices
During the past two decades, the decrease in intrinsic delay of MOSFETs has been driven by the scaling of the device dimensions. The performance improvement has relied mostly in the increase of source velocity with gate scaling, while the transport properties of the channel have remained constant, …

Failure mechanisms of thermal barrier coatings for high temperature gas turbine components under cyclic thermal loading
The mechanical behavior of PYSZ TBCs, deposited by EB-PVD and APS techniques, has been studied under thermal cyclic and isothermal loading. Two types of bond coats were chosen for the different multilayer systems: a single phase (Ni,Pt)-aluminide and a NiCoCrAlY overlay layer in the case of the …
