Structural fire endurance experiments were conducted on full-scale cellular glass fiber reinforced (GFRP) columns under axial compression and subjected to ISO 834 fire exposure from one side. Unprotected columns could resist fire for more than 30 min, whic ...

3D stacked circuits reduce communication delay in multicore system-on-chips (SoCs) and enable heterogeneous integration of cores, memories, sensors, and RF devices. However, vertical integration of layers exacerbates the reliability and thermal problems, a ...
Liquid cooling has emerged as a promising solution for addressing the elevated temperatures in 3D stacked architectures. In this work, we first propose a framework for detailed thermal modeling of the microchannels embedded between the tiers of the 3D syst ...
In jewelry manufacturing, joining dissimilar materials is usually achieved by brazing or soldering, in which the materials comprising the joint are heated to a suitable temperature in the presence of a filler metal having a liquidus below the solidus of th ...
Nowadays medium voltage conversion systems, like traction and energy distribution systems, aim to increase power density. Volume, weight and material reduction are gaining the market today. Due to the development of new high power semi-conductor devices a ...
Microcellular Al-4.5 wt pct Cu of 400- or 75-mu m average pore diameter is solidified at cooling rates ranging from -30 K/min to -0.45 K/min (-30 A degrees C/min to -0.45 A degrees C/min). In the 400-mu m pore size samples, the dendritic character is lost, ...
Gamma titanium aluminide (γ-TiAl) based alloys are very interesting materials for structural applications at elevated temperatures owing to the combination of high specific strength, good oxidation, creep and fatigue resistance. However, their relatively p ...
A phenomenological modelling approach has been developed to describe the massive transformation and the formation of lamellar microstructures during cooling in binary gamma titanium aluminides. The modelling approach is based on a combination of nucleation ...
Detailed surface measurements of the thermal performance of a film cooling system have been performed on the endwall of a nozzle guide vane (NGV) mounted in a linear cascade facility at EPFL. An external cooling scheme including several rows of fan-shaped ...
