Influence of technological and mechanical properties ratio of nickel-base heat-resistant alloy on ability to deep drawing

Abstract

One of the conditions ensuring the competitive advantages of a final product is the possibility of carrying out complex, resource-saving technological processes of workpiece shaping from the materials that provide necessary operational properties. In particular, such processes include the deep drawing of products. The advantages of deep drawing are a sufficiently high coefficient of used material, as well as an exceptional possibility of thin-walled deep detail manufacture from sheet blanks of "Gilsa" type. A prerequisite for the use of deep drawing is a series of technological and mechanical properties of material.

The article considers the estimation of possibility use for a deep drawing of nickel alloy ensuring the necessary level of operational properties of a product, first of all - heat resistance. The results of tests are provided evaluating the physical and mechanical properties of GH304 T14992-1994 alloy, as well as test data, on the basis of which they developed the recommendations for deep drawing of products made of nickel alloys.
