Abstract

The results of experimental investigation of mechanical properties of sheet metal from an experimental aluminum alloys Al–Mg system alloyed with scandium have been represented. It was established that the deformed and annealed semi-finished products of these alloys have higher strength properties. Testing of welded samples made from these semi-finished products showed high corrosion resistance and strength of welded joints.

Highlights

The problem of searching for new welded aluminum alloys having higher strength characteristics than existing industrial alloys of the Al-Mg system is most directly connected both with the creation of new, more sophisticated samples of new technology and with the solution of a number of national economic problems [1]
With the purpose of deeper studying the patterns of formation of mechanical and operational properties of products made of aluminum alloys economically alloyed with scandium, the employees of “RUSAL” together with scientists of the School of Non-Ferrous Metals and Materials Science of the Siberian Federal University have conducted a number of experimental studies in recent years with varying the chemical composition of alloys and regimes their processing, as well as produced batches of cast and deformed semi-finished products from them [13,14,15,16]
In the course of rolling, samples were taken for testing the mechanical properties and the temporary tensile strength Rm, yield strength Rp and elongation A10 for each sample studied of alloys

Summary

Introduction

The problem of searching for new welded aluminum alloys having higher strength characteristics than existing industrial alloys of the Al-Mg system is most directly connected both with the creation of new, more sophisticated samples of new technology and with the solution of a number of national economic problems [1].One of the most urgent problems of scientific and technical progress is the problem of increasing the weight perfection of missile and aircraft equipment, shipbuilding and the automotive industry. 1.
