Patcha Ramachandra Rao

Rao was a fellow of all four science and engineering academies of the country: Indian Academy of Sciences, Indian National Science Academy, National Academy of Sciences, India, and Indian National Academy of Engineering. He was also a fellow of The Academy of Sciences for the Developing World. He served in the council of Indian National Science Academy from 1996–98 and was serving vice-president when he died.

Rao was a Platinum Jubilee lecturer of Materials Science Section of Indian Science Congress at Goa in 1993, Prof. Brahm Prakash Memorial Lecturer at Indian Institute of Science in 2000 and both Daya Swarup and N.P. Gandhi Memorial Lecturer of the Indian Institute of Metals in 1998 and 2004 respectively.

Rao received numerous honours and awards. The prominent among them are Shanti Swarup Bhatnagar Prize for Science and Technology of CSIR in 1985, INSA Prize for Materials Science in 1997, National Metallurgist Award in 2004 and Shanti Swarup Bhatnagar Gold Medal of INSA in 2005. He received the Distinguished Alumnus Award of Indian Institute of Science as well as that of the Department of Metallurgy, Banaras Hindu University. He was a recipient of Nayudamma Award of CSIR in 1999. The engineering profession has recognised his contribution with Vasvik Award in 1997, Distinguished Engineer Award of Institution of Engineers and Om Prakash Bhasin Award in 1998. For his contribution to the first Indian space experiment, he was awarded Inter Cosmos Medal of USSR in 1984.

Dr. Rao was married to Sudha Rao in 1966. In his own words, "she has been a great support to me and let me pursue my professional life without any worry of running the family. She was herself an employee of Andhra Bank. She joined the Bank when it opened a branch in Varanasi at the beginning of 1980 and rose to become an officer.".

For the early part of his life, Rao's parents home-schooled him and admitted him to the seventh grade directly. He completed formal school at the early age of 13. Thereafter, he went on to study intermediate at the newly established Andhra Loyola College at Vijayawada and moved over to Osmania University, Hyderabad for higher education. At the young age of 19 years, in 1961, Rao graduated with a master's degree in Physics from the Osmania University in Hyderabad India. Thereafter, in 1963, Rao graduated from the Indian Institute of Sciences, Bangalore, with a B.E. degree in Metallurgy. During his second year at I.I.Sc Bangalore, Rao was supported by the Dorabji Tata Trust. His long association with the Banaras Hindu University (B.H.U) began soon afterwards, when his mentor T.R. Anantharaman encouraged him to enroll in the doctoral program at the Department of Metallurgical Engineering at B.H.U (now Indian Institute of Technology (BHU) Varanasi). Rao's pioneering doctoral dissertation in Rapid Solidification laid the foundation for the research in this area in India. He obtained his MSc in 1965 and PhD in 1968.

Rao pioneered research activities in the area of rapid solidification, an area pertaining to the solidification of liquids at the rate of a million degrees per second, in India in the mid 1960s. Such a process leads to the formation of extensive solid solutions, metastable intermediate phases and metallic glasses. He was the first outside the United States of America to conduct research in this technologically important area. Rao discovered novel intermetallic phases and also the hitherto unexpected phases with 5-fold rotational symmetry. His interests then shifted to identifying the theoretical basis of the formation of such phases and he began to model their formation from a thermodynamic standpoint. Some of the expressions developed for the free energy of undercooled liquids are being used extensively by modellers. The techniques of rapid solidification which were once a matter of scientific curiosity have now been industrially exploited by the advanced countries in the form of novel metallic glass-based transformer core materials, fine grained high strength alloys, new hard magnetic materials etc. Many noteworthy contributions made by Rao, his students and erstwhile colleagues at the Banaras Hindu University have brought immense recognition to India as an important centre for rapid solidification studies.

Patcha Ramachandra Rao (21 March 1942 – 10 January 2010) was a metallurgist and administrator. He has the unique distinction of being the only Vice-Chancellor (2002–05) of the Banaras Hindu University (BHU) who was also a student (1963–68) and faculty (1964–92) at that institution. From 1992 to 2002, Rao was the Director of the National Metallurgical Laboratory, Jamshedpur. After his tenure as Vice-Chancellor of B.H.U., in 2005, he took the reins of the Defence Institute of Advanced Technology (DIAT) as its first Vice-Chancellor. He was to serve DIAT until his superannuation in 2007. From 2007 till the end, Rao was a Raja Ramanna Fellow at the International Advanced Research Centre for Powder Metallurgy and New Materials, in Hyderabad, Andhra Pradesh.

Rao was born on 21 March 1942 to S. R. Narayanaswamy Naidu and Laxmi Bai at Kavutavaram in the Krishna District of Andhra Pradesh. His father Narayanaswamy Naidu, was a government servant and retired as Deputy Registrar of Co-operative Societies while his mother, Laxmi Bai was also educated and studied up to matriculation when very few women were going to school. From his mother's side, Rao is the nephew of Narla Venkateswara Rao, a Telugu language writer, journalist and politician from Andhra Pradesh, Narla Gowri Shankar Rao, an assistant accountant-general (retired) in the Central Government of India, and Narla Tata Rao, a doyen of the power sector in India and a former chairman of the Andhra Pradesh State Electricity Board.
