When high-Cr white cast iron contains 18%~28% Cr and Cr/C value is 8~9, the microstructure is tempered martensite + little retained austenite (<5%) + M7C3 carbide, and high impact toughness, high fracture toughness K1C, and high impact resistance and low spalling rate of grinding balls can be obtained.
Wavelets, generalized white noise and fractional integration: The synthesis of fractional Brownian motion
Assuming Hull and White model for the interest rates, a closed-form formula for geometric-average options is derived.
It is found that the head-on face (in contact with solution) of the films is green while the back face is white.
The impact of different interference substrate materials for improving the color travel effect was studied, and the influence of white and black background on the hue and the color travel effect were studied.
Theoretical and experimental study on white light interferometric sensing network with double-ring topology
