Norman Percy Allen
Norman Percy Allen was a British metallurgist.
Early life
He was born in Wrexham, North Wales, the son of accountant Sidney Edward Allen and educated at Burton-on-Trent Boys' Grammar School and Sheffield University, where he obtained an honours degree in metallurgy.Career
He stayed on at Sheffield to carry out research into copper die-casting alloys, but in 1925 moved to Swansea University to work for three years on the porosity of copper and copper alloys, moving again in 1929 to Birmingham University to continue the work. He was awarded a D.Sc. by Birmingham University in 1934.In 1933 he left the university to join Mond Nickel Company at their Birmingham research laboratory under Dr Leonard Bessemer Pfeil, where he stayed until 1945. During that time he worked on the development of highly alloyed nickel base materials Nimonic having high strength and high oxidation resistance at elevated temperatures which served a key role in the use of such alloys in the new jet engines.
In 1945, he joined the National Physical Laboratory as Superintendent of the Metallurgy Division, where he stayed until his retirement in 1969. A major project there concerned the development of superconductors, their manufacture, use and ongoing development. Other projects involved the development of physical methods of analysis such as spectrographic analysis, chromatography, colorimetry, X-ray fluorescence and absorption spectrometry. In 1966 he was appointed Deputy Director of the NPL.
