چکیده
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 borides as precipitates inside it. boronizing kinetics was investigated by using classical parabolic growth law. obtained value boron activation energy in entire (FeB + Fe found to be 236.34 kJ mol -1 . Furthermore, has been compared literature data. Finally, nanohardness reduced modulus elasticity measured FeB,

Optimization of process parameters for pulsed laser milling of micro-channels on AISI H13 tool steel
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...
متن کاملSurface integrity predictions and optimisation of machining conditions in the turning of AISI H13 tool steel
Surface integrity (SI) plays a very important role in functional performance. It is dependent on a large number of machining parameters. The major concern of industry is to know which combination of machining parameters provides the best SI of machined components. Traditionally, surface roughness is considered to be the principal parameter to assess the SI of a machined part. However, residual ...
متن کاملHot Forming of Aisi A2 Tool Steel
In order to optimize the hot forming process of tool steels, further improvement of flow stress prediction and additional knowledge on hot deformability, especially at lower and upper limits of the hot working range, are required. The hot working ranges for these steels are very narrow as a consequence of the role of alloying elements, which form carbides. Carbides improve tool steel’s hardenab...
متن کاملEVALUATION OF THE MECHANICAL PROPERTIES OF NIOBIUM MODIFIED CAST AISI H 13 HOT WORK TOOL STEEL
Abstract: mechanical properties of AISIH 13 hot-work tool steel have been studied. Cast samples made of the modified new steel were homogenized and austenitized at different conditions, followed by tempering at the specified temperature ranges. Hardness, red hardness, three point bending test and Charpy impact test were carried out to evaluate the mechanical properties together with characteriz...
متن کاملNickel-based Superalloy Layer Deposited on AISI H13 Hot Tool Steel Base Metal Using Explosion Cladding process
An experimental test was carried out to explosively clad solution annealed Inconel 718 superalloy on quench-tempered AISI H13 hot tool steel. A wavy with vortices interface geometry was obtained from this experiment. A gradual change in the wavelength along the direction of welding was observed which was due to a change in the impact angle, following the plate contacts. In this paper, the exper...
