“…The main problem is non-metallic inclusions in liquid metal, gas pores remaining in the composition due to the low gas permeability of the mold and Problems such as streaking during solidification of the liquid metal in the mold were observed (Figure 1). These defects are the main factors affecting the quality and mechanical properties of cast products [11][12]. Kaolin and bentonite clays are mainly used as binders in the mold compound when pouring high-quality bulk products into mold made of sand-clays.…”

This article examines the technology for producing high-quality steel and alloy castings in sand-clay molds. The optimization of the sandclay compound mold composition is explored, focusing on bentonite and kaolin clays as binders. The mold composition is refined based on the research conducted on these binding clays, resulting in the production of gas-free cast products. Additionally, the gas permeability of the sand-clay molds increased by 14-16%. The study also presents a test analysis of the gas permeability property, a crucial aspect of sand-clay mold quality. Furthermore, a mathematical model of the process was developed from the research findings to predict gas permeability values with varying amounts of binding clays, eliminating the need for further testing.

“…It noticeable the the value of the coefficient in front of the highest level of the variable in the polynomials that the polynomials (functions) created with our limitation allow us obtain information with an accuracy of 10 -3 ...10 -4 . Also, these models ( 6), (9), and ( 12) allow us to determine the next results of the HSS tool flank wear without conducting experiments, based on the results of the conducted experiments. However, considering the cutting speed gradient from 0 to 60 mm/s, developed models are reliable when the selected experimental conditions are used in the machining process.…”

“…In the current paradigm of machining methodologies [8,9], the efficiency and costeffectiveness of manufacturing operations are significantly influenced by the performance and durability of cutting tools. In turning applications utilizing high-speed steel (HSS) [10], the occurrence of flank wear on cutting tools [11,12] emerges as a crucial factor influencing tool lifespan and, consequently, machining productivity.…”

In this article, mathematical models of the High-Speed Steel (HSS) cutting tool flank wear in various external metal cutting environments are developed. Initially, the metal machining operation is conducted in a lathe by machining a cylindrical blank of Stal 45 (analog is AISI 1045) with a turning tool made of P6M5 (analog is AISI M2). The machining process is conducted in three external cutting environments: dry cutting and two different cutting fluid environments. According to tool flank wear results from the experimental research in cutting conditions, three novel mathematical models of the tool flank wear have been developed using the Lagrange polynomial. The models express the flank wear of the HSS cutting tool depending on the cutting speed changes in three various external cutting environments. Developed models were tested using engineering programs, and tool wear indications depending on the cutting speed acquired from the novel models were compared to the original results achieved by the experimental research. Consentaneity of the results taken using the models to the experimental research data was about 93 %, 86%, and 93% for the three models respectively.

In this study, the impact of titanium (Ti) on low-alloy steel alloys is examined, focusing on the mechanical properties of the alloy with varying Ti content levels. Heat treatment was conducted to enhance the mechanical properties and performance indicators of the casting samples. The elemental volume distribution mapping and microstructure analysis of the research samples were performed using SEM - Carl Zeiss Ultra Plus Field Emission. Subsequently, the hardness and wear resistance characteristics of samples containing Ti contents of 0, 0.1, 0.3, 0.5, 0.8, and 1.1 were evaluated post heat treatment. Notably, steel samples containing 0.3% and 0.5% Ti, exhibiting structures of ferrite, martensite, and limited bainite, demonstrated superior hardness and wear resistance properties. Abrasive wear resistance tests were conducted using a specialized device with a horizontal diamond disc. The primary objective of this research is to introduce the developed technology for the rolling mill rolls at a prominent metal manufacturing enterprise in the republic, resulting in enhanced economic efficiency through increased production volume. Consequently, achieving a hardness of HB 323 and improving wear resistance by 1.2 times were notable outcomes of the study.
