    摘要： A strike tip (100) for a pick tool, comprising a strike structure (120) joined to a substrate (110) at an interface boundary (115), the strike structure (120) comprising or consisting or super-hard material and the substrate (110) comprising or consisting of carbide material; the strike tip having a proximate strike end (117) coterminous with the super-hard material and a distal end (118) defined by the substrate (110), a side connecting the strike and distal ends; the strike end (117) including a flat apex area (150) and an outer area extending from the apex to the side. The apex area (150) is substantially less than the outer area, and is at least 1 square millimeter and at most 25 square millimeters.

    摘要： A cemented carbide material comprising tungsten carbide grains, the content of tungsten carbide in the cemented carbide material being at least 75 weight percent and at most 95 weight percent. The cemented carbide material comprises a binder phase comprising any of cobalt, iron, or nickel, and nanoparticles. The nanoparticles include material according to the formula CoxWyCz, where x is a value in the range from 1 to 7, y is a value in the range from 1 to 10 and z is a value in the range from 0 to 4. The nanoparticles have a mean grain size of no more than 10 nm and at least 10 percent of the nanoparticles have a size of at most 5 nm. The volume percent of the tungsten carbide grains having a grain size of no more than 1 μm is less than 4 percent. A method for producing the cemented carbide material is also disclosed.

    摘要： A pick tool assembly (100) comprises a strike tip (210), a holder (230) and a reversible attachment mechanism 245, 350) for coupling the strike tip (210) to the holder (230), in which the strike tip (210) comprises a strike surface including an apex. The pick tool assembly (100) will be configured such that the strike tip (210) can be non-moveably coupled to the holder (230) in a plurality of mutually opposite orientations relative to the holder, the orientations being about a symmetry axis (L) through the apex. The attachment mechanism will limit the opposite orientations (245-ii, 245-ii) to being at least about 160 degrees azimuthally apart, and be configured such that the strike tip (210) may be coupled to the holder assembly (230) in either of two and only two mutually opposite orientations.
