| Abstract: | Full examination and analyses are made for the fracture of the 30MnSi High Strength Reinforced Bar which broken during the usage, metallographic structure, parent material in rolling situation (billets) and etching for the casting billets. The result indicates that the metallurgical defects in the casting is the reason that cause the brittle fracture of the reinforced bars, and the change of the environmental temperature only has the function of catalysis. |
