28 Jun 2024: Steels for rails. W. Solano-Alvarez and H. K. D. H. Bhadeshia. Abstract. Transport by rail is an efficient way of moving goods and people while managing problems such as congestion and the consequences on the environment. The relatively low energy

24 Jun 2024: Continuously cooled hypoeutectoid steel. H. K. D. H. Bhadeshia. The vast majority of the 1.3 billion tonnes of steel proudced annually have a microstructure which is a mixture of allotriomorphic ferrite and pearlite. The pearlite is the last phase
