摘要
Abstract
The sample of the cracking hub was observed and analyzed by means of optical microscope and electron microprobe to find out the causes for the cracking .The results showed that Cr ,Mo ,some bright segregation bands and many inclusions were observed in the hub .The observations and analysis concluded that the segregation bands caused by segregation of Cr ,Mo would produce a great stress be-tween segregation bands when the hub was forged while the presence of inclusions destroyed the continuity of the base plate ,causing the crack and the crack expanding .关键词
