Abstract In this work, the borided layers were produced on AISI H13 steel via solid boriding with a powders mixture containing 90 wt.% B 4 C and 10 NaBF for treatment times of 2-6 h at 900, 950 1000 °C. The microscopic observations revealed less pronounced toothed interface between layer transition zone. XRD studies indicated presence dual phase boride (FeB/Fe 2 B) besides chromium vanadium bor...

This paper presents a study of the relationship between Electrical Discharge Machining (EDM) parameters on the EDM efficiency factors using a full factorial design, based on pulse on-time, duty cycle and tool polarity parameters in EDM machining of AISI H13 tool steel. The results show that, in positive polarity, the plasma flushing efficiency and pulse efficiency increase according to the puls...

in this study the effect of input parameters of the edm process (pulse on-time, duty cycle and tool polarity), on the material removal rate (mrr), tool wear ratio (twr) and maximum surface roughness (rmax) in the machining aisi h13 tool steel has been studied. this study shows that increasing the duty cycle in the two conditions of tool polarity, material removal rate and the maximum surface ro...

Hot working tool steel (AISI H13) is one of the most common die materials used in casting industries. A suffers from damage due to friction and wear during its lifetime. Therefore, various methods have been developed for repair save costs manufacture a new one. great benefit laser additive manufacturing (cladding) 3D high production rate with minimal influence thermal stresses comparison conven...

In this research work a series of tests were conducted in order to determine flank wear and cutting force FY on hard AISI 440 C martensitic stainless steel and SCM 440 alloy steels. The operating parameters are cutting speed, feed rate and a constant depth of cut to investigate the flank wear and cutting force. No cutting fluid was used during the turning process. The cutting tool used was CBN ...

Abstract Electron beam powder bed fusion (E-PBF) is a well-known additive manufacturing process. Components are realized based on layer-by-layer melting of metal powder. Due to the high degree design freedom, came into focus tooling industry, especially for tools with sophisticated internal cooling channels. The present work focuses relationships between processing, microstructure evolution, ch...
