The vibration unsteady condition of rolling mill caused by flexural vibration of strip has been investigated. The parametric flexural vibration equation of roll
The effects of Al2O3 fiber on wear characteristics of eutectic Al-Si alloy composites were studied using a pin-on-disk tester under dry sliding condition. The r
The structure of liquid indium was studied at 280, 390, 550, 650, 750℃, respectively, by using an elevated temperature X-ray diffractometer. The diffraction in
The Nb-10Si (mole fraction, %) alloy was fabricated using the vacuum arc-melting method and heat-treated at 1850 ℃ and 1550 ℃ for 2~100h in Ar at mosphere. The
