Hardness Test of Welded Joints Produced by Resistance Spot Welding of Nanostructured Titanium Alloy VT6
Abstract
The paper presents the results of investigating the structure and mechanical properties of welded joints obtained by resistance spot welding of titanium alloy VT6 under the sub-microcrystalline condition. A nonmonotone microhardness modification is obtained in the weld zone. It is shown that microhardness in the heat-affected zone is 20 % lower than that of the base metal. At the same time, microhardness in the centre of the weld is 20 % higher than that in the base metal.
