Machine Learning classification models have been trained and validated from a dataset (73 features 13,616 instances) including experimental information of clean cold forming steel fabricated by electric arc furnace hot rolling. A model was developed to identify inclusion contents above the median. The following algorithms were implemented: Logistic Regression, K-Nearest Neighbors, Decision Tree...

In the two last decades, world production of pig iron and steel has undergone a significant increase. 2018, 1252.87 1806.46 million tons steel, respectively, were produced as compared to 575.78 809.94 2000. Consequently, amount different types slags deriving from these processes also increased considerably. relation principles sustainability circular economy, available literature suggests sever...

This paper reviews the previous literature on alloy composition design of low-density steel (LDS), focusing effect Al, Mn, Ni, and other elements formation matrix second phase, provides classification. The microstructure LDS after processing includes structure, к-carbide, B2 (FeAl, NiAl, or MnAl) phase ferritic LDS, austenitic dual-phase LDS. influence corrosion resistance is derived from addit...

Steel foams have attracted a lot of attention in both academia and industry with unique properties such as low density, high strength-to-weight ratio, operating temperature, good energy absorption, electrical conductivity, large specific surface. The development production methods will increase the use steel foam. In this paper, Cr-Mo alloyed having porosities range 46.8-71.3% were produced by ...

In recent years, the rolling densification process has become increasingly widely used to strengthen powder metallurgy parts. The original composition of the rolled powder metallurgy blank has a significant effect on the rolling densification technology. The present work investigated the effects of different carbon contents (0 wt. %, 0.2 wt. %, 0.45 wt. %, and 0.8 wt. %) on the rolling densific...
