Abstract

Purpose.  Comparative studies of the mechanical properties of steels at different temperatures for testing of railway wheels of different chemical composition. Methods. Pull test at stretching by high temperatures at GOST 9651, test the percussion bend at low temperatures were made according at GOST 9454 specimen taken from the rims of solid-rolled railway wheels of steel “2”, “T” and “K”, manufacture of PJSC “Interpipe NTRP". Results. Increasing temperature pull test results in reduced strength in varying  degrees  depending  on  the  chemical  composition  of  the steels.  Plastic  properties  of  steels  thus  have  a  different  character depending.  The  most  sensitive  was  relatively  narrowing.  It  is  found  that  at  subcritical  temperatures  until  a  change  of  phase composition,  relative  narrowing  steel  "C"  is  significantly  superior  to  other  investigated  steel  reaches  90%.  That  is,  the  strain localization  under  the  new  brand  is  characterized  by  high  resistance  to  fracture  and  cracking.  Employment  impact  at  low temperatures experienced grade "K" has a level of a value close to the mark "2", and is significantly higher (by 2.5-3 times) valuesfor the brand "T". Originality.  The regularities of the influence of the test temperature on the mechanical properties of the rims of railway  wheels  of  different  chemical:  indicators  of  strength,  ductility  and  toughness of  steel.  It  was  found  that  the  change  in  the mechanical  properties  of  the  steel  has  a  different  character  when  the  temperature  changes. Practical  value. Solid-rolled  railway wheels of steel  "K" have  a high  operational reliability,  since a range of indicators of strength  and ductility  at high  temperatures, impact energy at low temperatures it is much superior to the existing analogues.
