Selective laser melting of tungsten carbide reinforced maraging steel composite

Low-Cycle Fatigue Behaviour of AISI 18Ni300 Maraging Steel Produced by Selective Laser Melting

Selective laser melting has received a great deal of attention in recent years. Nevertheless, research has been mainly focused on the technical issues and their relationship with the final microstructure and monotonic properties. Fatigue behaviour has rarely been addressed, and the emphasis has been placed on high-cycle regimes. The aim of this paper is, therefore, to study, in a systematic man...

Modeling of graphitization kinetics during peritectic melting of tungsten carbide

A dynamic computational model developed within the context of the classical theory of phase evolution is applied to the W–C system to simulate the kinetics of graphite nucleation during non-equilibrium peritectic melting of WC. The kinetic variables used in the model are obtained directly from the free energy formulations that characterize the stable and metastable equilibria between WC, liquid...

Check Tic-coated Tungsten Carbide Tool Wear in Machining Steel

In industrial production systems, including the most important factors in the economic field machining operations, reduce tool wear due to abrasive nature of the phenomenon on many factors, including temperature Lathe tool, influences, machining conditions (cutting speed, speed losses, forcing to rebuild parts of the manufacturing tolerances disassemble tool wear is caused by the phenomenon, as...

Modeling of selective laser sintering/selective laser melting

Selective laser sintering and selective laser melting are powder based additive manufacturing (AM) process that can rapidly manufacture parts with comparable mechanical properties to conventional manufacturing methods directly from digital files. However, the processing recipe development and design optimization of AM parts are often based on trial and error which erodes the benefit of AM. Mode...
