Investigation of Hardness and Impact Toughness of Zr-Microalloyed Cast Steel
Microalloyed cast steels are a group of microalloyed steels in which reliable mechanical properties could be achieved by heat treatment. In this work, the heat treatment processes were carried out on the cast specimens as the step samples by different thicknesses and Zr content. The results show that after homogenization, variations in thickness have no effect on the hardness. Also, after hea...
متن کاملti - microalloyed steel, quenched from hot forging temperature
the aim of the paper presented here is to develop the ti - micralloyed steel in otrer to oprtmize the mechanical properties after direct quenching from hot forging temperature. for this purpose, seven melts containing various amounts of titanium were prepared and cast in metal and sand molds. from the ingots, cast in metal mould, tractor links were produced by hot forging. the produced links we...

متن کاملPrediction of forging force and barreling behavior in isothermal hot forging of AlCuMgPb aluminum alloy using artificial neural network
In the present investigation, an artificial neural network (ANN) model is developed to predict the isothermal hot forging behavior of AlCuMgPb aluminum alloy. The inputs of the ANN are deformation temperature, frictional factor, ram velocity and displacement whereas the forging force, barreling parameter and final shape are considered as the output variable. The developed feed-forward back-prop...
متن کاملHot Flashless Precision Forging of Long Pieces
Within the net-shape and near-net shape technology hot flashless precision forging leads to high forging accuracy of the workpiece with regard to dimensional and surface finish tolerances. The main advantages are shortened production cycles by eliminating machining operations and the saving on raw material lost during machining. By producing ready-to-mount forgings high economical and ecologica...
