THE WELDABILITY ASSESSMENT OF THERMALLY HARDENED S540Q STEEL SHEETS

High strength thermally hardened steels are more difficult to weld than low carbon construction steels. There is a danger of cold cracking caused by the presence of martensite in welded joints. The thermally hardened 12...

THE FATIGUE STRENGTH EVALUATION OF S540Q STEEL AND ITS WELDED JOINTS

The research deals with the examination of thermally hardened sheets of weldable S540Q steel of high strength, obtained by thermo mechanical treatment. Conventional rolling and controlled rolling with rapid cooling proce...

EFFECT OF FINISHING ON THE CORROSION PROPERTIES OF FLAME SPRAYED Ni-5%Al AND Ni-5%Al-Al2O3 COATINGS

The Ni-5%Al alloy and Ni-5% Al-Al2O3 composite coatings were obtained by a flame spraying method, “Casto-Dyn DS 8000” torch was used. The coatings onto a substrate made of austenitic stainless steel (X5CrNi18-10) were sp...
