The behaviour of aluminium-chromium ferritic steels in simulated coal gasification atmospheres at 723 K
Two aluminium-chromium ferritic steels were exposed to simulated coal gasifier atmospheres for times of up to 900 h at 723 K. High-resolution analytical transmission electron microscopy was used to study the development ...
The electromagnetic field in rotating coordinates
The electromagnetic field equations in rotating coordinates obtained by various authors, are based on incorrect expressions for the divergence and curl operators and the electromagnetic spatial vectors. This is a serious ...
Approximate expressions of maximum value of stress intensity factor of nozzle corner cracks
Based on the flat plate-nozzle model loaded by uniform uniaxial tension, through some suitable reduction and approximation, the maximum value of stress intensity factor (K) along a crack front can be expressed by the weight ...
