Gupta, Surojit, Filimonov, D., Palanisamy, T., El-Raghy, T., Barsoum, Michel W.
The tribological performances of the two new composite materials, consisting of the layered ternary carbides (MAX phases), Ta2AlC or Cr2AlC, and 20 vol.% Ag, were investigated in the temperature...
Ambient and 550 oC tribological behavior of select MAX phases against Ni-based superalloys (2007)
Gupta, Surojit, Filimonov, D., Zaitsev, V., Palanisamy, T., Barsoum, Michel W.
In this paper, we report on the tribological behavior, at 25 and 550 ◦C of the following layered (MAX phase) ternary carbides: Ti2AlC, Cr2AlC, Ta2AlC, Ti3SiC2, Ti2AlN, Ti4AlN3, Cr2GeC, Cr2GaC,...
Isothermal oxidation of Ta2ALC in air (2006)
Gupta, Surojit, Filimonov, D., Barsoum, Michel W.
The oxidation behavior, in air, of bulk polycrystalline Ta2AlC samples was studied in the 6001–9001C temperature range. A protective, essentially X-ray amorphous, oxide layer—which does not...
Tribology of MAX phases and their composites (2006)
Currently there is a need for triboactive materials for high-speed turbomachinery applications in industry, which possess: (a) adequate mechanical strength, both at room and elevated temperatures...
Compression behavior of M2AlC (M=Ti, V, Cr, Nb, and Ta) phases to above 50 GPa (2006)
ManounManoun, Bouchaib, Gulve, R. P., Saxena, S. K., Gupta, Surojit, Barsoum, Michel W., Zha, C. S.
The compression behavior of the hexagonal MAX phases M2AlC (M=Ti, V, Cr, Nb, and Ta)—selected because they represent two series; a horizontal series in which the atomic number of the M element...

Spontaneous growth of freestanding Ga nanoribbons from Cr2GaC surfaces (2005)
Sun, Zheng Ming, Gupta, Surojit, Ye, Haihui, Barsoum, Michel W.
Herein we report on the room-temperature spontaneous growth of Ga freestanding nanoribbons from Cr2GaC surfaces. An oxidation-based model is proposed to explain the growth of the nanostructures. The...
Hettinger, J. D., Lofland, S.E., Meehan, T., Palma, J., Harrell, K., Gupta, Surojit, ...
In this paper we report on a systematic investigation, in the 5 to 300 K temperature regime, of the electronic, magnetotransport, thermoelectric, thermal, and elastic properties of four M2AlC phases:...
Spanier, Jonathan E., Gupta, Surojit, Amer, Maher, Barsoum, Michel W.
We report on the Raman spectra of Ti3SiC2 (312), M2AlC (211) (M=Ti, V, Cr, and Nb) and Ti4AlN3 (413), as representative compounds from the family of Mn+1AXn phases. Intense and narrow first-order...
Driving force and mechanism for spontaneous metal whisker formation (2004)
Barsoum, Michel W., Hoffman, Elizabeth N., Doherty, Roger D., Gupta, Surojit, Zavaliangos, Antonios
The room temperature spontaneous growth of low melting point metal whiskers, such as Sn, poses a serious reliability problem in the semiconducting industry; a problem that has become acute with the...
