    Different types of diamonds are available. Tests have shown that the high material removal, together with a shallow scratch depth, is obtained because of the many small cutting edges of polycrystalline diamonds. Silicon carbide, SIC, with a hardness of about 2,500 HV, is a widely used abrasive for grinding papers for mainly non-ferrous metals

    Rapid mechanochemical synthesis of amorphous alloys:

    Apr 04, 2017 A rapid method for preparing amorphous alloys has been developed utilizing a SPEX high energy ball mill. Parameters such as ball size, mass of balls and milling time, were systematically optimized to prepare amorphous alloys quickly. Amorphous alloys previously not thought possible to synthesize by means of SPEX milling were made amorphous by the new method. . When applied to
