Aluminium matrix composites (AMCs) can be used in applications which require high strength and hardness. Present work aims to explore the influence of titanium diboride (TiB2) addition on structure properties A713-TiB2 composites. The were fabricated using stir casting route by varying weight fractions (0, 2, 4, 6 wt.%) TiB2 particles. All cast at same level stirring time (10 min) speed (500 rpm). Microstructural characterisation, microhardness tensile testing have been carried out. It has...
The surface of gray cast iron has been modified by Tungsten Inert Gas (TIG) process. Welding current magnitude 25, 35, and 45 amperes have used to melt the iron. Microstructural characterization, hardness measurement dry sliding wear tests performed on these surfaces. It observed that increase in welding caused microstructure grey be gradually refined. Graphite flakes segregated between interdendritic regions as-received completely replaced a uniform distribution finer graphite matrix....
Due to its solid-state nature, friction stir welding (FSW) process can be considered a better alternative for dissimilar metals. However, like fusion techniques, in growth of thick layers brittle intermetallics - Cu9Al4 and CuAl2 is significant issue. One solution this problem the use suitable interlayer material. Use material modifies joint microstructure with replacement thick, by more ductile thin layer or particle form. The present study preliminary investigation about joining AA6082-O...
A parametric experimental investigation has been conducted to investigate effects of stir casting process parameters on recently developed A713-TiB2 composites. The manufacturing involved varying the stirring time (5, 10, and 15 minutes) speed (500, 600 & 700 rpm). microstructure mechanical properties manufactured composites were evaluated by analyzing speeds times. analysis techniques used include optical microscopy (OM), scanning electron (SEM), micro-hardness tensile testing....
An experimental investigation on effect of friction stir lap welding (FSLW) process parameters mechanical and microstructure AA6082-O welds is presented. Three namely tool rotational speed (1000,1400 & 2000 rpm), shoulder diameter (18, 20 22 mm) traverse (28, 56 80 mm/min) are considered. Experiments planned as per L9 Taguchi array. Data analyzed in terms S/N ratio Analysis Variance (ANOVA). Tensile shear strength observed the range 11.79 MPa to 29.23 MPa. It that most significant...
