Influence of FSW parameters on formation quality and mechanical properties of Al 2024-T351 butt welded joints
(Elsevier, Amsterdam, 2013)
The influence of R/v ratio on joint quality in 2024-T351 aluminum alloy was studied. Specimens were subjected to friction stir welding with the rotation rates of 750, 950 and 1180 r/min and welding speed between 73 and 190 ...
Sensitivity analysis of mathematical models for final product properties: Link to DTG curve
(Elsevier Sci Ltd, Oxford, 2013)
Compressive strength and water absorption of fired heavy clay products varies with firing temperatures, but not entirely according to linear function, as it is mostly reported in literature. Also, differential thermo-gravimetric ...
