a low carbon al-killed ti-added steel was produced in mobarakeh steel complex in iran. mechanical properties and microstructural characterizations of steel in the as-cast, hot-rolled, cold-rolled and annealed conditions are presented. dilatometery tests were carried out to measure the finishing and annealing temperatures of steel. it was found that the addition of small amounts of ti increased ...

The influence of short-time heat treatment on the widely used and commercially available ledeburitic cold-work tool steel 1.2379 (X153CrMoV12; AISI D2) is examined herein. Starting from a soft annealed initial condition, different austenitizing temperatures holding times metastable microstructural states after treatment/hardening investigated. experimental implementation in quenching dilatomete...

in this work, the influence of different edm parameters (pulse current, pulse voltage, pulse on-time , pulse off-time) in finishing stage on  the surface roughness (r a )  as a result of application copper electrode to a workpiece( cold work steel  din1.2379)  has been investigated. design of the experiment was chosen as full factorial. statistical analysis has been done and artificial neural n...

Repair welding (RW) with wire cladding is a common procedure to extend the in-service life of heavily loaded tool parts for die and mould industries 1-5 . The main advantages of repair welding are short downtime and cost efficiency compared to production of new tool part. Repair welding in general lowers the tool cost in the final part and enables higher added value to the die casting and injec...

C and Z sections are two of the most common cold-formed steel shapes in use today. Accurate prediction of the bending performance of these sections is important for reliable and efficient cold-formed steel structures. Recent analytical work has highlighted discontinuities and inconsistencies in the American Iron and Steel Institute ~AISI! and Canadian Standards Association ~S136! design provisi...

This paper presents the suitable depth of cut, spindle speed and feed rate that will be chosen during machining. If thus parameters are not considered, this can provoke abnormal tool behavior such as chatter. Chatter will limit the tool life which only can be use for just a few times. To predict the chatter occurs, the parameters will be use are spindle speed, depth of cut and feed rate. CNC ma...
