Purpose: This work concerns manufacturing and research on a new group of the gradient tool materials, manufactured by the conventional powder metallurgy method, consisting in compacting a powder in a closed die and sintering it. Design/methodology/approach: The materials were obtained by mixing the powders of the HS6-5-2 high-speed steel, tungsten carbide (WC). The mixes were poured one after another...

Purpose: This work concerns research on the structure and properties of gradient tool materials with the HS6-5-2 high-speed steel matrix reinforced by the tungsten carbide. Design/methodology/approach: The materials were fabricated using the conventional powder metallurgy method, consisting in compacting the powder in a closed die, and subsequent sintering. All the sintered test pieces were subjected...
Purpose: The goal of this work is to obtain gradient carbide steels based on a high-speed steel reinforced with tungsten carbide. Design/methodology/approach: The materials were fabricated using the conventional powder metallurgy method. The gradient carbide steels was fabricated by mixing high-speed steel with WC powders. The uniaxial pressing before sintering was used for manufacturing the materials,...
