Hot work tool steel (AISI H13) and high speed steel (AISI M3:2) powders were successfully co-sintered to produce hybrid tool steels that have properties and microstructures that can be modulated for specific applications. To promote co-sintering, which is made difficult by the various densification kinetics of the two steels, the particle sizes and structures were refined by mechanical milling ...

The aim of this paper was to study the effects of die life through shot peening treatments on AISI H13 steel, and tests were performed to study the influential parameters of the shot peening process. To evaluate the effects of microstructure and the die life of AISI H13 steel after steel shot peening processes, we conducted and evaluated roughness tests, micro hardness and wear tests, and SEM m...

Improvement of die life in the hot forging of brass alloys is considered vital from both technical and economical points of view. In this research, pin-ondisc tests were carried out at a range of temperatures to evaluate the influence of plasma nitriding and duplex nitriding-physical vapour deposition (PVD), including TiN-TiAlN and TiN-TiAlN-CrAlN coatings, on the tribological properties of AIS...

This paper focuses on understanding the influence of laser milling process parameters on the final geometrical and surface quality of micro-channel features fabricated on AISI H13 steel. Optimal selection of process parameters is highly critical for successful material removal and high dimensional and surface quality for micro-sized die/mold applications. A set of designed experiments is carrie...

H13 steel is a widely used hot work die material. A new type of hot working method is imperative to develop complex and precise dies. In this paper, the heat treatment of H13 steel (AISI) was carried out by annealing, the final structure is a point or spherical pearlite, and the grain size is about 30-40 μm. The tensile properties of the annealed microstructure were investigated at 650, 750, an...

In this study, 3-D finite element modeling of precision hard turning has been used to investigate the effects of cutting edge microgeometry on tool forces, temperatures and stresses in machining of AISI H13 steel using polycrystalline cubic boron nitrite (PCBN) inserts with two distinct edge preparations. Hard turning experiments were conducted to investigate the effects of cutting edge geometr...

In this study, machinability tests on Assab Korkmaz Orvar Supreme (1.2344 ESR, AISI H13 Premium) hot work tool steel widely used in industry were carried out. Machinability tests were carried out through single point turning method at eight different cutting speeds (120, 160, 200, 240, 280, 320, 360 ve 400 m/dak), four different feed rates (0,05; 0,10; 0,15 and 0,20 mm/min) and 1 mm depth of cu...
