Study of the Metal Properties and Structure of a Large Shell Made of 15Kh2MFA Steel

Homogenization of Cr-Ni Austenitic Steel Studying: Liquation and Microhardness Heterogeneity Equalization

“…The production of forged ring blanks from new steel (with higher nickel content) requires revision of the existing metallurgical technology at all stages of production: metal smelting, ingot casting, plastic and thermal processing. It should be noted that the reliability and durability of the reactor pressure vessel and its internals under operating conditions is determined not only by the average level of physical and mechanical properties of the steel, but also by the homogeneity of these properties in the entire volume of metallurgical blanks [3][4][5].…”

Determination of Boundary Parameters of Pipelines Elbows Blanking Elements Made from Titanium Alloy Ti-4Al-2Mn and Steel AISI 304

“…Bend angle ϕ=90° Bend angle ϕ=60° Bend angle ϕ=45° Characteristic features of considered parts are their geometric shape, which leads to a high nonuniformity of deformations in the process of shaping. Such unhomogeneity of deformations can lead to two main types of defects: 1. corrugation on the side surface of the product; 2. destruction of the product at the output end of the minimum bend radius [12][13][14].…”

Quasi-Optimal Correlation Algorithm for Measuring the Parameters of Surface Microrelief

“…This will significantly improve the performance of the correlation method of estimating the microrelief parameters under production conditions. To significantly improve the speed of the method proposed in [10,18], quasi-optimal correlation algorithms were considered. These algorithms are widely used in the correlation extremal navigation systems (ESCS) on digital terrain maps of unmanned aerial vehicles.…”
