...Ch. Mohana Rao; K. Mallikarjuna Rao Purpose The objective of the paper is to evaluate the fabrication process and to study the influence of process parameters of friction stir processing of 6061-TiB₂-Al₂O₃ Aluminum alloy surface composite on microhardness tensile...

.../SS304, have shown improved corrosion resistance compared with virgin 304 substrate. Microhardness was carried out using Vickers method; the microhardness values for TiN/SS304 and TiAlVN/SS304 were approximately 7.5 GPa and 25.3 GPa, respectively. The paper aims to discuss these issues. Design...

... characteristics of joints. FSW parameters are optimized to maximize the yield strength and weld nugget microhardness of the welded joints. Design/methodology/approach Response surface methodology is applied to establish the mathematical relationship between six input factors, namely, tool rotational speed...

... aluminum alloys. In order to test the reliability of nanoindentation technique, nanohardness values for friction stir welded aluminum alloys were compared to microhardness values. Additionally, the onset of plasticity (yielding) is investigated. Design/methodology/approach Nanoindentation experiments...
