Effect of Additives on Eutectoid Reaction and Mechanical Properties of Nb-Nb5Si3 Alloys
Published online by Cambridge University Press: 10 February 2011
Extract
For the improvement of mechanical properties, especially ductility, of intermetallic compoundbased alloys, microstructural control has been adopted to binary and higher-order systems. Although lamellar structure formed by a eutectic reaction has been attracting broad attention to ductilize alloys with a combination of brittle/ductile or brittle/brittle phases, it should be pointed out that the microstructure such as lamellar size or colony size is hard to be controlled after the solidification process. In that viewpoint, high-temperature solid-solid phase transformation provide significant advantages in handling and large super-cooling for the control of lamellar structure through eutectoid reaction.
