PHYSICAL MODELING OF HOT PLASTIC DEFORMATION PROCESS OF POWDER HIGH-SPEED STEEL ON THE GLEEBLE 3800 COMPLEX

Abstract

In the present work, obtained billets from powder high-speed steel by the HIP method. Samples were tested at various speeds and degrees of hot plastic deformation, which are modeled on the Gleeble-3800 complex. The total number of samples is 8. The generalized experimental results cover almost the entire range of high-speed deformation modes of hot rolling mills and can be used to develop technological processes for metal forming when producing blanks for cutting tools in a wide size range.
