Purpose. The aim of the work was to study peculiarities crack initiation in heterophase inclusions "high-melting phase surrounded by a low-melting shell" type during deformation steels. Methods. destruction various types investigated specimens from steels 08T, 08Yu, 12GS, 08kp, 09G2S, NB-57, 08GSYuTF temperature range 20...1 200 °C [1; 5]. Samples were subjected tension, compression and bending...

Abstract A metallurgical study of a Renaissance spearhead from northern Italy was performed to provide new deep insights into both smelting and smithing technologies which are involved in the manufacturing process. Optical microscopy observations, Vickers microhardness measurements, optical emission spectroscopy analyses demonstrated that skillfully assembled shaped different steel bars, slack-...

The characteristics of nonmetallic inclusions (NMIs) in low‐alloyed steel samples taken during ladle treatment before and after Ca are evaluated using the pulse distribution analysis optical emission spectroscopy (PDA/OES) method, INCA‐Feature investigations on a polished surface samples, 3D NMIs electrolytic extraction (EE) samples. investigation results different methods were compared. PDA/OE...

Although continuous casting is the state‐of‐the‐art method in steelmaking, ingot by bottom teeming has kept its relevance, for example, area of specialty steels. The main challenge to meet ever‐increasing quality requirements demanded customers. Regarding high‐performance steel applications, purity with respect content nonmetallic inclusions thereby special interest. Herein, foam templates tail...
