Resistance to brittle failure is one of the most important characteristics of materials and structures operating under conditions of low temperatures; this also includes rails. It was established that for nonheat-treated (NH) as well as for bulk-hard

Studies of the crack resistance of nonthermally strengthened (NT), bulk hardened (BH), and surface hardened type R65 rails of quality groups I and II are presented. Results are summarized for tests on 616 full-profile rail samples from 57 different b

1. It was establised that crack resistance limit Ic determined in full-profile nonheat-treated rails with cross fatigue cracks of area 10...30% of the rail head cross-sectional area is practically constant. The breaking stress σc in all the cases is

1. The work of crack initiation can be determined in the impact tests on the full-profile rail specimens. 2. The energy of fracture of the full-profile rail specimens is greatly scattered as a result of the presence of various external and internal s
