Nickel-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...
متن کاملOptimization 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 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 کاملLaser deposited TiC/H13 tool steel composite coatings and their erosion resistance
The present work studies the synthesis and performance of TiC/H13 tool steel composite coatings obtained by the laser deposition technique. he effect of laser beam-scanning speeds and the concentrations of TiC in injected powder on the morphologies and microstructures of deposited eads are investigated. The results show that the beam-scanning speeds affect the size and morphology of the beads. ...
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 ...
