ОБРАБОТКА МЕТАЛЛОВ № 1 (70) 2016 66 МАТЕРИАЛОВЕДЕНИЕ This investigation has shown that the normalization of rail aluminotermitic welded joints reduces the probability of occurrence of brittle destruction in the heat affected zone during the operation of continuous welded rail. Keywords: rails, aluminotermitic welding, heat treatment, microstructure, hardness, rails joints. DOI: 10.17212/1994-6309-2016-1-60-66 References 1. Pas’ko S.V., Tikhomirova L.B., Bolotova O.V.
