FeAl materials from intermetallic powders

Rapid consolidation of nanostructured FeAl compound by high frequency induction heating and its mechanical properties

“…Godlewska et al investigated FeAl sintered from the selfpropagating high-temperature synthesized powders followed by hot forging. The hardness and grain size of FeAl were 274 kg/mm 2 and 24 (radial), 8.2 (axial) m [19]. The hardness of this study is higher than that of Goglewska's work due to refinement of grain size.…”

Combustion synthesis of Mg2Si

“…Indeed, the reaction proceeds according to the self-propagating mechanism, provided the suitable conditions are secured. Unlike in the synthesis of iron aluminides [11], where the initial shape of preforms remains almost unchanged, magnesium silicide is disintegrates into fine powder. For the subsequent consolidation, the powder product, which does not require milling, appears very advantageous.…”

Intermetallics Synthesis in the Fe–Al System via Layer by Layer 3D Laser Cladding

“…Therefore, attempts are made to obtain the Fe-Al intermetallic samples and coating by alternative methods, such as a thermal spraying and magnetron sputtering [6][7][8], Self-propagated High-temperature Synthesis (SHS) [9,10] and laser additive manufacturing (LAM) (3D laser cladding, direct metal deposition (DMD), laser engineered net shaping (LENS), selective laser melting (SLM) processes) [11][12][13][14][15][16][17][18]. Nevertheless, these methods also have a number of negative factors, such as porosity and high connection strength due to the difference in the temperature expansion coefficients of the coating and base layer, which decrease the effectiveness of these approaches.…”
