The manufacturing of Dual-Phase steels includes as a crucial step the annealing cold-rolled ferrite-pearlite (F/P) microstructure, which involves numerous and interacting metallurgical mechanisms, namely recovery/recrystallization ferrite, globularization, manganese enrichment, coarsening cementite finally austenite transformation. Present study focuses on transformation considering its interac...

Addition of titanium (Ti) to ASTM A710 Grade B Cu-precipitation-strengthened steel significantly increases the impact absorbed fracture energy and reduces the ductile-to-brittle transition temperature. The effect of Ti correlates with the reduction of the amount of pearlite in the ferritic microstructure. A thorough study of the mechanical properties of Ti-modified A 710-B steel is presented.

This paper studies the temperature field, dynamic strain, and forming accuracy of oscillate-WAAM conical shell in process manufactures WAAM part. The results show that compared with offset filling WAAM, shows following characteristics: difference value between inner outer walls is significantly reduced, cooling rate doubled decreased, interlayer above 300 °C, average gradient, strain stability ...

this experiment was conducted to evaluate the effects of salt stress on some agro-physiological traits in ten varieties of bread (triticum aestivum l.) and durum (triticum turgidum l.) wheats in seedling stage. a greenhouse experiment was carried out as a split plot experiment based on a completely randomized design with four replications in hydroponic condition. different agronomic and physiol...

the main aim of this project was the assessment, for the first time, anthropometrically, the nutritional status in school girls' population aging from 7 to 10 years in ahwaz city and ultimately compare their growth rate with other findings obtained from different part of iran and also with the proposed standards of nchs in this respect. this study was conducted on 1200 apparently healthy school...
