Performance Assessment of Spray Formed AISI M2 High-Speed Steel Tools


Article Preview

Machining tools (interchangeable inserts) were manufactured from spray formed AISI M2 high-speed steel. The spray formed materials were mechanical and microstructural characterised. An assessment of the machining performance of the spray formed high-speed steel was attained. These results were compared to materials obtained by conventional and powder metallurgy techniques. The results showed that under the used process conditions (hot rolling and heat treating), the spray formed material showed a machining behaviour near closed to other materials; and highlight the potential of the spray forming technique for the obtention of materials with adequate properties for machining tools manufacturing.
