Intrinsic brittleness
WebIn materials science, brittleness is understood as the lack of ductility. For engineers, the understanding of the difference between brittle and ductile material is of the highest … WebIt is well known that single crystals of Ni[sub 3]Al are ductile, whereas polycrystalline Ni[sub 3]Al has very low ductility at room temperature due to the intrinsic brittleness of its grain boundaries, which results in premature intergranular fracture.
