Tungsten Granules & Transcrystalline Cleavage Fracture

Most of tungsten granules present transcrystalline cleavage fracture. Binder phase presents ductile fracture and shows better mechanical properties. Remaining organics are not deprived completely during thermal derosination. So, precious few parts in sample have foreign impurities. Those foreign impurities are the key factors for influencing mechanical properties. For that, compared with tensile strength detection result of standard tensile sample, tensile strength of matter sample is low.

Most of tungsten granules present transcrystalline cleavage fracture. Interface of tungsten granules breach and tungsten granules are smashed. What is different is that individual white foreign impurities exist in fracture pattern. Because of large sizes of samples, previously few high polymer organics are not deprived completely and produce carbon inclusions. For that, impact ductility of matter samples is low.
