Growth and characterization of the NiAl–NiAlNb eutectic structure

Experimental investigation of the effect of solidification processing parameters on the rod spacings in the Sn–1.2wt.% Cu alloy

“…These exponent values of 0.50, 0.49 and 0.50 relating to the growth rate obtained in the present work are in good agreement with the exponent values of V obtained in previous works [11,[14][15][16][17][18][19][20][21][22][23] These exponent values of 0.52, 0.51 and 0.49 relating to the temperature gradient obtained in the present work are in good agreement with the exponent value of 0.52 relating to the growth rate (V) obtained by Böyük et al [32]. 4.…”

“…Our exponent values (0.50) are in good agreement with 0.46, 0.50 and 0.49 values obtained by Wilde et al [14] for Al-25.6 wt.% Cu-24.5 wt.% Ag, Ç adırlı et al [15], Witusiewicz et al [16] for In-33.10 wt.% Bi-15.56 wt.% Sn ternary alloys, respectively, but the value of 0.58, found by Grugel-Brush [17] is greater than the result obtained in present work for Sn-Cu eutectic system. The exponent values of V obtained in the present work are very close to the value of 0.50 obtained by different workers [11,[18][19][20][21][22][23] for Al-Cu binary eutectic alloy.…”

Microstructure and room temperature fracture toughness of directionally solidified NiAl–Mo eutectic in situ composites

“…The intermetallic compound NiAl has long been identified as a promising candidate for high-temperature structural applications in aggressive environments, because it possesses attractive combination of properties including high melting point (1638 C), high thermal conductivity (w80 W/mK), lower density (w5.86 g/cm 3 ) and superior oxidation resistance up to 1300 C [1e3]. However, like many other intermetallics, its intrinsic brittleness and insufficient room temperature fracture toughness restrict its utilization.…”

Microstructure characterization and room temperature deformation of a rapidly solidified NiAl-based eutectic alloy containing trace Dy

“…This higher level of growth rate may lead to some deviation from the eutectic composition. Also, the high growth rate may restrict the co-operative growth, which leads to primary dendritic phase formation [14].…”
