On the relation between the microstructure and the mechanical behavior

The aim of this work is to relate the evolution of the microstructure and the texture with the mechanical behavior of pure Zn processed by HPT at room temperature, which is approximately equivalent to a homologous processing temperature (T proc /T m) of 0.43. Both the hardness and the in-plane tensile mechanical properties were analyzed.

Electronic shutter vs mechanical shutter

With a mechanical shutter, in principle, the entire sensor is exposed with a very short time elapsing between the first and second shutter curtains, capturing the whole of the frame at that moment (left). With an electronic shutter, however (middle two illustrations), the sensor data is read from top to bottom as if in slices, which is slower ...
