Abstract: Hydrogen may cause severe degradation on some high strength alloys, and although research efforts have intensified in recent years, our understanding of such phenomena still has room for improvement. For the metallurgical industry it would be useful to have applicable criteria able to predict the risk of hydrogen embrittlement and therefore be able to prevent embritlement damage to industrial products.

Abstract: The main problem in production of forgings from tool steels, especially in the form of thick plates, blocks, and rods which are used for special machine components for demanding applications, is the inhomogeneous structure with segregations, cracks in segregations or complex type of non-metallic inclusions of MnS and TiCN type. These forgings are actually produced from conventional forging ingots. [..] Read more

Abstract: Traditionally, scrap has been the raw materials feed to the electric arc furnace, but increasingly direct reduced iron (DRI), pre reduced pellets and hot briquetted iron (HBI) are being focused as potential alternative charge materials for the electric arc furnace. The partial substitution of scrap by these charge materials directly affecting on the quality of steel and process consumptions in electric arc furnace. [..] Read more

Abstract: The article describes an approach to decreasing the rejection rate of the steel plates due to the surface defects in the rolling mill achieved by optimization of air-water secondary cooling on the continuous casting machine (CCM) of steel. In context with the occurrence of the surface cracks on the steel plates a complex analysis of possible reasons causing the creation of monitored cracks was made. [..] Read more

Abstract: The paper is devoted to the study of the influence of experimental conditions of the direct thermal analysis method for use in high-temperature thermal analysis equipment Netzsch STA 449 F3 JUPITER during controlled cooling mode.The first part of the article is focused on monitoring of the effect of experimental conditions on the solidification point of the standard material nickel (a purity of 99.995 %) and the total shape of cooling curve. On the basis of experimental measurements, a deviation obtained by interpreting the cooling curves for various cooling rates (5; 10; 15 and 20 °C min-1) for nickel samples of various weights (5; 10; 15 and 20 g) from the generally recognized melting / solidification point of nickel (1455 °C) can be quantified.Besides the identification of the influence of experimental conditions on the temperature of solidification and the total cooling curve of nickel shape during solidification, the paper focuses attention on the mapping and interpreting the response found during the solidification of steel sample and the resulting to liquidus (TL) and solidus (TS) temperature of this steel.
