bearing will be influenced. The geometric error degrades the mechanical performance of rolling bearing [2]. Therefore, it is desirable to investigate the mechanical behavior of cross roller bearings... J. Cent. South Univ.

Hydroforming of AZ61A tubular component with various cross sections TANG Ze-jun(汤泽军), HE Zhu-bin(何祝斌), LIU Gang(刘 钢) YUAN Shi-jian(苑世剑), HU Lan(胡 蓝) School of Materials Science... suitable for hydroforming of the AZ61A magnesium alloy tube with various cross sections. Pre-forming and hydroforming with high strain values are feasible at elevated temperature. Grain refinement......
September 2009; accepted 30 January 2010 Abstract: Two rolling ways, unidirectional rolling and cross rolling, were carried out on twin roll cast AZ31 alloy sheet to study the influence of strain.... It is found that cross rolling gives rise to more uniform microstructure and stronger texture intensities compared with unidirectional rolling. The differences in the microstructure and texture intensities......
