Research Highlights
Creep and Superplasticity
I have evaluated creep and superplastic behavior of a number of materials, including aluminum
alloys and composites, titanium alloys, titanium aluminides, nickel base superalloys,
quasicrystals, and nanocrystalline alloys. Some of my contributions include, models for threshold
for diffusional creep in pure metals and dislocation creep in dispersion strengthened materials.
When I started following the controversies involving creep of aluminum matrix composites, I
thought that microstructural parameters influence the dominant creep micro-mechanisms. This
led to the development of dislocation creep mechanism map. I still believe that the constitutive
relationships for dislocation creep need to include microstructural parameters and we are
working on this. Based on similar thought processes, I put together a mechanism transition map
for high strain rate superplasticity in particle containing aluminum alloys. Some of my papers
have been received quite well by other researchers (I have included a list of well cited papers).
Working on nanocrystalline materials, I highlighted the fact that nanocrystalline materials exhibit
different high temperature deformation kinetics. Detailed analysis has shown that the change in
deformation rate cannot be completely accounted by the grain size alone. From 1999, I also
started organizing creep symposium under the TMS umbrella.

composites. The paper has been cited very well by the researchers in this field.
Processing and Properties of Bulk Ultrafine Grained Materials
Ultrafine grained materials are defined as materials with grain size <1m. I am including my
efforts on nanocrystalline materials under this category. My interest in bulk ultrafine grained
materials was motivated by two questions: (a) what is the critical grain size below which the
micro-mechanisms involved in mechanical behavior would change? (b) how to process bulk
ultrafine grained materials at elevated processing temperatures without excessive grain growth?
Resume of R. S. Mishra – 25
My initial work was on synthesis of ceramics with high-hardness and high toughness. The work
resulted in a US patent on alumina-diamond nanocomposite and an invention disclosure on
alumina-niobium nanocomposite apart from research publications. The main accomplishment
was synthesis of fully dense nanocrystalline materials using high pressure and low temperatures.
At UMR, I have focused on bulk nanostructured aluminum alloys using various powder
metallurgy approaches. Most of the work has been done in collaboration with Boeing and Pratt &
Whitney. We have managed to get funding from NSF, AFOSR and DARPA to pursue some of
these research activities. We are currently working on obtaining a combination of high strength
and good ductility. We have succeeded in obtaining strength of 700 MPa and ductility of >5%
using secondary processing of rolling and forging in ultrafine grained aluminum alloy under the
DARPA program with Boeing. By understanding the flow behavior at elevated temperatures, we
have managed to find a narrow temperature range where secondary processing results in
improved ductility without the loss of strength.

Friction Stir Welding and Processing
When I started research work on friction stir welding with the help from Murray Mahoney of
Rockwell Scientific, I saw the opportunity to expand this technique beyond joining. So far we
have obtained three US patents on selective superplasticity, microforming and channeling using
friction stir processing. I collaborated with Kumar Jata and Murray Mahoney to start coorganizing symposium on friction stir welding and processing under the TMS umbrella. We
recognized that publication of proceedings in this fast growing field will be very useful. I have
written the first comprehensive review on friction stir welding and processing. It was published
in the Materials Science and Engineering: Reports journal. I selected this review journal based on
the impact factor (currently 11.8, highest among any materials science journals). Currently we are
focusing on the fundamentals of microstructural evolution during friction stir processing and its

influence on properties. Using small tool design, we have managed to produce ultrafine grained
aluminum alloys with ~0.7 m grain size in one pass. This has resulted in superplasticity below
200oC in aluminum alloys, as compared to >400oC for conventionally processed aluminum
alloys. We have joined a four-university consortium on NSF Industry/University Cooperative
Research Center. I have been able to get General Motors, Boeing, Pacific Northwest National
Laboratory, and Friction Stir Link to join the UMR site as industrial members. The center
operates on NSF funding as well as industrial membership fees.

Selected Publications of R. S. Mishra
(Impact of Scientific Publications)
It is generally very difficult to judge the quality of scientific research and publications of a researcher.
However, the ‘Science Citation Index’ provides one such measure. Hirsch has produced an h-index to measure
output of a researcher based on citations (Nature, Vol 436, page 18 August 2005; arXiv:physics/0508025 v3 17 Aug
2005). A key definition is, “A scientist has index h if h of his/her Np papers have at least h citations each, and the
other (Np − h) papers have fewer than h citations each. My current ‘h-index’ is 35, i.e. I have 35 papers that have
been cited more than 35 times according to the Science Citation Index (as on March 13, 2011). This can be
considered as an indirect testimony to the impact of my research efforts. My ‘n’ is 23 based on first
publication in 1987. This gives ‘m=(h/n)’ of 1.52.
To help with the interpretation of the numbers above, I am reproducing a paragraph from Hirsh’s paper,
“Based on typical h and m values found, I suggest that (with large error bars) for faculty at research universities h
~ 12 should be a typical value for advancement to tenure (associate professor), and h ~ 18 for advancement to full
professor. Fellowship in the American Physical Society should occur typically for h ~ 15 to 20. Membership in the
US National Academy of Sciences should typically be associated with h ~ 45 and higher except in exceptional
circumstances. Note that these estimates correspond roughly to typical number of years of sustained research
production assuming an m ~ 1 value, the time scales of course will be shorter for scientists with higher m values.
Note that the time estimates are taken from the publication of the first paper which typically occurs some years
before the Ph.D. is earned.”
