The influence of the thermomechanical effects on optical properties germanium microstructures is investigated. Finite element method (FEM) calculations allow a complete spatial assessment mechanical deformations induced by silicon nitride (SiN) stressor layer deposited Ge micropillars. Simulated strain maps are confirmed experimental obtained Raman spectroscopy. theoretical investigation strain...

Epoxy systems are widely used as matrix resins for fiber reinforced polymers (FRP) and, therefore, often have to withstand harsh environmental conditions. Especially in marine and offshore environments, moisture or direct water contact leads absorption into the epoxy resin. As a result, mechanical properties change during application. Since diffusion at room colder temperatures is slow, industr...

The mechanical properties and microstructural developments of 321 stainless steel during thermomechanical process were investigated. The repetitive cold rolling and subsequent annealing were conducted to achieve nanocrystalline structure in an AISI 321 stainless steel. Heavily cold rolling at −20°C was conducted to form martensite in metastable austenitic steel. The process was followed by anne...
