| Abstract: | In this article analyse the fracture reason of the foot backle using to climb poles. Obviously it is caused by the decarbonization and the martensitic matrix thickening, both are the relust of extra high temperature duing the hardening procedure,as well as not undergoing sufficient and effectiue tempering,stress concentrating on the welding position ,which causes the fragiling steel and bad performance. |
| Keywords: | martensitic matrix thickening decarbonisation stree concentrating |
