Název v původním jazyce

Formation of Intermetallics during Reactive Sintering Production of Fe-Al Alloys

Popis výsledku v původním jazyce

Fe-Al alloys have been known for more than 100 years. Their exceptional oxidation and sulphidation resistance makes them promising for many industrial applications. However, these materials suffer from poor room-temperature ductility and problems duringa production by conventional melting metallurgy. Therefore, reactive sintering of iron and aluminium compressed powder mixtures have been proposed as the alternative technology of their production. Unfortunately, this production technology leads to highly porous products. There are many theories why the porosity is so high and all of them deal with the intermetallic phases' formation mechanisms. There are at least three different phases' formation sequences during heating described in the literature. Inthis work, the in situ high energy X-ray diffraction analysis was carried out during the reactive sintering process and the mechanism of the formation of intermetallics in FeAl25 powder mixture was described during isothermal annealing a
