Journal ArticleDOI
Tensile and wear behaviour of in situ Al-7Si/TiB2 particulate composites
TL;DR: In this paper, an Al-7Si alloy reinforced with in situ TiB 2 particles was synthesized successfully by using salt reaction route and the in situ composites have shown significant improvement in mechanical properties in comparison to the base alloy.
Journal ArticleDOI
A synchrotron X-ray radiography study of dendrite fragmentation induced by a pulsed electromagnetic field in an Al–15Cu alloy
E. Liotti,A. Lui,Robin Vincent,S. Kumar,Zhipeng Guo,Thomas Connolley,I. P. Dolbnya,Michael Hart,Lars Arnberg,Ragnvald H. Mathiesen,Patrick S. Grant +10 more
TL;DR: An in situ technique for studying the effect of a pulsed electromagnetic field on dendrite fragmentation behavior based on synchrotron X-ray imaging has been developed, involving the passage of an oscillating current through a foil specimen placed in a static magnetic field as mentioned in this paper.
Journal ArticleDOI
Effect of reinforcement size and volume fraction on the abrasive wear behaviour of AA7075 Al/SiCp P/M composites—A statistical analysis
S. Kumar,V. Balasubramanian +1 more
TL;DR: In this paper, a new mathematical model was developed to predict the abrasive wear rate of AA7075 aluminum alloy matrix composites reinforced with SiC particles, five factors, five levels, central composite, rotable design matrix was used to optimise the required number of experiments.
Journal ArticleDOI
Developing a mathematical model to evaluate wear rate of AA7075/SiCp powder metallurgy composites
S. Kumar,V. Balasubramanian +1 more
TL;DR: In this article, the dry sliding wear behavior of AA7075 aluminium/SiC p composites fabricated by powder metallurgy technique is reported, where five factors, five levels, central composite, rotable design matrix is used to optimize the required number of experiments.
Journal ArticleDOI
A Comparative Study on the Microstructures and Mechanical Properties of Al 6061 Alloy and the MMC Al 6061/TiB2/12P
T.V. Christy,N. Murugan,S. Kumar +2 more
TL;DR: A comparison of the mechanical properties and the microstructure of Al 6061 alloy with Al-TiB2 metal matrix composite containing 12% by weight TiB2p manufactured through the in-situ process was presented in this article.
