Abstract
Compression tests are described to determine the flow stresses of steel of specifications: En 1A, En 8, En 26, En 30B, En 58 and 6:5:2 and 18:4:1 high-speed steels, which are presented for use in the analysis of metal working operations. Testing temperatures of 600°C, 800°C, 1000°C and 1200°C were employed and using each of two high-speed hammers and a mechanical press, strain-rates ranging from approximately 12/s to 2500/s were obtained.
