Hardening of Side Faces of Railheads by Electric Beam Treatment in Air

Metal Science and Heat Treatment Aims and scope

Abstract

We consider structural changes occurring upon electron-beam hardening in air of rail steel M76. The microhardness of the hardened zone (thickness about 1.2 mm) is 800 – 900 HV. The short-term drawback using electron beam provides reduction of the microhardness to 400 – 700 HV. Electron-beam hardening also provides a 2-3 fold increase in the wear resistance of steel under the effect of abrasive particles. The data thus obtained make it possible to recommend the method of electron-beam treatment to strengthen the side edge of rail heads.
