Hot Rolling of Brittle Fe-40at.%Al Type Alloy

Popis výsledku v původním jazyce

Using special protective capsules, laboratory castings made of the binary alloy of type Fe-40at.%Al, which is difficult to form, were successfully hot rolled. The rolling was performed from thickness 20 to 13 mm with 6 or 4 passes. Regardless of the wayof production and processing of samples, rolled products without surface cracks had always been obtained, but with some pores and/or cavities and indications of internal intercrystalline cracks. It may be considered to be a success, with regard to the fact that initial grains were extremely coarsened due to the previous homogenization annealing 1200 °C / 24 hours. Structural analyses were particularly aggravated by considerable heterogeneity and coarseness of the material in all phases of its processing. The forming and intermediate annealing of semifinished products and slow cooling of finished rolled products initiated recrystallization which under any circumstances did not lead to gain of the uniform microstructure, however.
