O.2021-06-022021-06-022021Defects of castings [Electronic resource] : methodical instructions for laboratory work in the discipline "Foundry alloys and smelting technologies" for students of specialty 131 Applied Mechanics of the Bachelor's level. Pt. 1 / comp. K. O. Kostyk ; National technical university "Kharkiv Polytechnic Institute". – Electronic text data. – Kharkiv, 2021. – 36 p. – URI: http://repository.kpi.kharkov.ua/handle/KhPI-Press/52957.https://repository.kpi.kharkov.ua/handle/KhPI-Press/52957Methodical instructions are intended for students of the specialty 131 Applied Mechanics of the Bachelor's level. Laboratory works are small study researches that allow students to get acquainted in more detail with the main defects of castings of the first and second groups and methods of their definition, to study features of formation of defects from geometry and surface defects. Each laboratory work contains a list of materials, a summary of theoretical information and research methods, the order of execution, which helps students to correctly and consciously perform the practical part of the work and draw conclusions. The purpose of the methodological instructions is to help students to study more deeply the topic "Inconsistency in geometry, surface defects of castings" in the discipline "Foundry alloys and smelting technologies", to develop skills of independent work and scientific research. In addition to the main goal, the methodological instructions are aimed at developing interest in scientific activity, familiarity with complex and varied experimental techniques, and will help students in the future in completing their thesis.enmethodical instructionsresearch materialclassification of the first group of defectsnon-ferrous metalssubstantive provisionsironLearning Objecthttps://orcid.org/0000-0003-4139-9970
