alloying with Mo and Cr additions. Key words: β-nickel aluminide; eutectic alloy; compressive properties; brittleness; ductility; fracture morphology 1 Introduction NiAl intermetallic alloys have...]. However, to make NiAl a viable structural material, it is necessary to overcome some of its inherent problems. These include low ductility and fracture toughness at ambient temperatures and inadequate......
s-1, respectively. Tensile tests showed a "hot ductility trough" at 950 °C for both alloys. The drop in hot ductility was more considerable in the cast alloy because of the sluggish dynamic recrystallization. The hot ductility drop and grain boundary cracking, particularly in the cast alloy, were attributed to the segregation of detrimental atoms to the boundaries. It was shown that the hot......

temperature. Commercial pure titanium with grain size of 18μm and 55μm were obtained after annealed at 650℃ and 800℃, respectively. The tensile properties show that ductility of titanium increases with increase of grain size from 18μm to 55μm at room temperature and -196℃, and twinning seems to become more common in coarsening grains. All the results imply that higher ductility in coarsening grain......
