A detail that
surprised us

“

Brahm Prakash’s decision to use Maraging Steel for rocket motor casings at VSSC became a foundational material choice still employed decades later in India’s PSLV and GSLV launch vehicles.

The Story

1
In 1942, Brahm Prakash earned his Ph.D. in physical metallurgy from Punjab University, Lahore, during a time when metallurgy was still an emerging discipline in India.
2
🎓 By 1949, after completing a second Ph.D. at MIT in Mineral Engineering and Metallurgical Thermodynamics, he returned to India to join Homi Bhabha's Atomic Energy Establishment, marking a critical step in India's nuclear materials development.
3🔬 In 1951, he became the first Indian head of the Department of Metallurgy at the Indian Institute of Science, Bangalore, where he expanded metallurgical research and education amid India’s early industrialization.
4⚛️ From 1957 to 1972, Brahm Prakash led the fabrication of nuclear fuel elements for the CIRUS reactor, including zirconium sponge and zircaloy cladding, essential for India's atomic energy programme’s self-reliance.
