Effect of thermomechanical processing on structure and properties of low carbon steels
(1989) Bimal Kumar Panigrahi; Vaidyanatha Ramaswamy; Suraj Bhan
The microstructure of one plain carbon and two microalloyed steels has been refined by two different thermomechanical processing schedules in a laboratory rolling mill. The factors controlling the structural refinement have been investigated. The results indicate that a combination of single/two stage rolling prior to reaustenitization treatment and finish rolling in the (α + γ) region, followed by controlled cooling, improves the mechanical properties by refining the ferrite grain size.
PHASE TRANSFORMATION STUDIES ON Fe-Co-Sn ALLOYS.
(1985) Vijay Kumar Singh; Mrityunjaya Singh; Suraj Bhan
Phase transformations in (FeCo)//7//5Sn//2//5 alloys have been studied by X-ray diffraction, scanning electron microscopy and hardness measurements. The phases in the quenched alloys are alpha -Fe(Sn), Fe//1//. //3 Sn, Fe//3Sn//2, Co//3Sn//2 and alpha -Co(Sn). The lattice constants have been determined. Preliminary diffraction studies have indicated the necessity of reinvestigation of high temperature phase equilibria.
