Laser Cladding of Cold-Work Tool Steel by Pulse Shaping

Journal of Materials Science and Technology, 2011
Repair welding of cold-work tool steels in cold is very risky and almost impossible by conventional processes. The application of pulse shaping in laser cladding with wire to avoid the solidification problems in relevant steel is demonstrated. The results show that sound remelting and/or cladding can be achieved by the right selection of laser ...

Selection of Steels and Coatings for Cold-Work Tools

Materials and Manufacturing Processes, 2009
Selection of tool steel grades and PVD coatings is of key importance for the tool longevity. Therefore, it is very important to recognize all present wear mechanisms in tool operation and select the most influential one, which enables proper selection of the tool steel grade for the active tool positions. The case study of certain tool steel selections

Evolution of carbides in cold-work tool steels

Materials Characterization, 2015
Abstract This study aimed to present the complete history of carbide evolution in a cold-work tool steel along its full processing route for fabrication and application. A sequence of processes from cast to final hardening heat treatment was conducted on an 8% Cr-steel to reproduce a typical commercial processing route in a small scale.

Tool steels for cold working dies

Metal Science and Heat Treatment, 2006
The effect of the main alloying elements (Cr, W, Mo, Ni, Mn, Si) and carbon on the properties of die steels used for cold deformation of metals is considered. Steels heat-treated for primary and secondary hardness are studied. The problems of ensuring maximum values of the impact toughness, strength characteristics, and fatigue limit at optimum content

Kinetic Investigations of Boronized Cold Work Tool Steels

Materials Testing, 2014
Abstract In this study, kinetic examinations on boronized X45NiCrMo4 (DIN 1.2767) and 90MnCrV8 (DIN 1.2842) steel samples are described. Samples were boronized in indirect heated fluidized bed furnace at 1123 K, 1223 K, and 1323 K for 1 h, 2 h, and 4 h.

Optimised sintering route for cold work tool steels

Powder Metallurgy, 2006
Two different powder metallurgy cold work tool steels, D7 and a nickel alloyed D7 modification, were compacted to full density by utilisation of super solidus liquid phase sintering in vacuum and nitrogen atmospheres. The experiments were carried out with respect to the fabrication of wear resistant metal matrix composites.

Cutting force in peripheral milling of cold work tool steel

Materials Research Proceedings, 2023
Abstract. Tool steels have been commonly applied to die and mold parts because of the high strength and the high abrasive wear resistance obtained by the heat treatments. In order to achieve high machining rate, the heat-treated tool steels have recently finished with end mills coated by hard thin layers.

Phase transformation of a cold work tool steel during tempering

Journal of Iron and Steel Research International, 2016
Abstract The hardness and microstructure evolution of a 8% Cr cold work tool steel during tempering for 40 h were investigated. Transmission electron microscope examinations showed that M3C carbides precipitated from supersaturated martensite after tempering at 350 °C.
