In recent years many different ways have been investigated by steel producers to increase ductility, impact strength and formability of steels. More important ways are steels with very low amounts of inclusion, small size inclusions and modified inclusions. In this study, experiments have been performed on the API-X42 steel produced by the electric arc furnace in Mobarekeh Steel Co. After the p...

This article introduces the microstructural and mechanical properties of low medium-carbon advanced martensitic steels (AMSs) subjected to heat-treatment, hot- warm- working, and/or case-hardening processes. The AMSs developed for sheet wire rod products have a tensile strength higher than 1.5 GPa, good cold-formability, superior toughness fatigue strength, delayed fracture due mixture martensi...

In the face of an oversupplied world pig market only the most efficient producers will stay in business. By and large these will be the operations that are able to more successfully exploit the genetic potential of their animals. Similarly, only those breeders who are able to demonstrate sustained genetic improvement will sell stock to the smaller number of large producers who are left. Althoug...

In the case shown here, skeletal plates in the zygomatic buttress allowed us to transmit orthodontic forces from the molars to the maxilla for posterior vertical intrusion. This article will examine the orthodontic mechanics needed to control the ratio of the moment of couple (MC) to the moment of force (MF) and the load-deflection ratio, working within the range, strength, and formability of t...

This paper refers to some simulation tests concerning the formability and springback of a U-shaped part manufactured from tailor welded stripes. The final geometry of the obtained part is seriously affected by springback phenomenon. This paper work is trying to prove out the important role samples dimension has on the springback phenomenon. The influence of the samples width on the tailor welde...
