Increasing the hot workability and expanding the temperature working range for M35 high-speed steel (HSS) by industrial hot rolling as well as by hot compression tests have been studied and achieved. The types of carbides for as-cast as well as for wrought states were revealed by EBSD and the optimal soaking temperatures for both microstructural states were assessed. The soaking temperature had a decisive influence on the characteristics of carbides that lead to improving the intrinsic hot…

Correlation Between the Indentation Properties and Microstructure of Dissimilar Capacitor Discharge Welded WC-Co/High-Speed Steel Joints
A novel capacitor discharge welding (CDW) process is investigated for the case of a butt-joint between a tungsten carbide-cobalt composite rod and an AISI M35 high-speed steel (HSS) rod, which shows no hardness deterioration on the HSS side of the weld zone, although a slight decrease in hardness was observed across the transitional layer on the composite side.


Strength and structure under hot-working conditions
AbstractThe main feature of hot working is that extremely large strains are applied to materials at high rates of strain at temperatures above ∼ 0.6Tm, where Tm is the melting temperature in degrees
Three Important Points that Relate to Improving the Hot Workability of Ledeburitic Tool Steels
In this article, the importance of selecting the right process parameters for ledeburitic tool steels, i.e., casting temperature, cooling rate, and soaking temperature, which is needed to improve
Hot Ductility of Tool Steels
Abstract Four tool steels (A2, D2, M2 and W1) representing a wide variety of compositions (and carbide content) were hot deformed in torsion between 900 and 1200 °C at strain rates of 0.1, 1 and 4
Microstructural changes in As— Cast M2
High speed steels have a complex carbide pattern in the as-cast state which has to be modified to achieve the desired properties of adequate toughness, hot hardness, and wear resistance. The effects
