Name of student : Mr. Hariprasad G Thesis Title : “Synthesis, microstructural stability and high temperature deformation of alumina carbon nanotubes composites” Faculty advisor : Prof. Atul H Chokshi Date : Tuesday 5th December 2017 Time : 11.00 A.M Venue : Materials Engineering Lecture Theatre Abstract: Alumimium oxide is a structural ceramic material which finds numerous applications in diverse fields. Poor fracture toughness and high temperature formability are difficulties that restrict its widespread use. Carbon nanotubes (CNT) are possibly ideal reinforcements to overcome some of these shortcomings. However, a uniform dispersion of carbon nanotubes in alumina poses a significant challenge, which needs to be addressed to realize the potential benefits offered by CNT reinforcement. This thesis deals with processing techniques to obtain a uniform, well dispersed CNT dispersed alumina composite. The microstructural stability is assessed through high temperature grain growth experiments. It is observed that with relatively small CNT additions,the matrix grain size is stabilized to a submicrocrystalline size regime. A limiting grain size is observed in all composites above a nominal CNT volume fraction. The influence of CNTs in the grain growth behaviour is analyzed through a grain boundary dragging model and the effect of the CNT volume fraction on the limiting grain size is understood using a geometrical model. The high temperature deformation behaviour of the composites is studied using constant load compression creep experiments. Steady state creep behaviour is observed for all composites. At modest temperatures and applied stresses the composites deform with fairly high strain rates. The influence of CNT reinforcement and the effect of volume fraction is analysed by comparing results with creep data for pure alumina. In conjunction with microstructural characterization and experimental determination of creep parameters, the deformation mechanism of CNT reinforced alumina composites is deduced as Coble diffusion creep and interface reaction controlled Coble creep. Based on the recent diffusivity measurements obtained from the literature, it was observed that the creep data agreed well with the theoretical predictions from a Coble creep deformation.

This year’s edition of NMD-ATM, the flagship event of the Indian Institute of Metals, will be held in Goa (in BITS-Pilani, Goa Campus) during 11-14 November 2017.
As we did in the previous years — IIT-BHU (2013), Pune (2014), Coimbatore (2015), IIT-Kanpur (2016) — we are organizing an Alumni Reception during NMD-ATM this year as well. This subscription (Rs. 1,500; please bring change!) event is scheduled for the evening (6:30 p.m. onwards) of Sunday, 12 November 2017 in Bogmallo Beach Resort.
The Bogmallo Beach Resort is about 7 Km from the BITS-Pilani, Goa Campus. The recommended transport Ola / Uber / Auto, which should take no more than 13 mins from the conference venue. Ask / look for “IISc-Met Alumni reception”.
