Makes an assessment of 5378 papers published by Indian Institute of Technology Madras and 4430 papers published by Indian Institute of Technology Bombay respectively indexed by the Scopus database in the field of Engineering Sciences and its sub-field during 2006-2015. The study indicates that the number of papers grew during the period of study. The findings indicate that the researchers of both the IITs in the field of engineering sciences published their papers in global journals published from USA, UK and Germany and other countries of the West. Around 19.66% papers published by IITM scientists and 26.54% papers published by IITB scientists in engineering sciences during 2006-2015 remained uncited. More authors from IITB were highly cited as compared to IITM.

Being very strong and of limited ductility, Ti alloys require special techniques to manufacture the parts with complex shapes. Many of these technologies are based on superplastic and near-to-superplastic deforming. In these processes the transformation of the microstructure of the material can be very significant and can lead to changes in the mechanical properties of the material during deformation. Because of this an appropriate description of the correlation between mechanical loading, changes in microstructure and mechanical behavior of material is required. A phenomenological scalar model with an internal variable based on a statistical description of microstructure is proposed and used for simulation of the high temperature deformation of Ti-6Al-4V alloy. The problems of obtaining the parameters of the model and sensitivity of the model to the accuracy of this process are discussed.
