Axel Hultgren

Axel Gustaf Emanuel Hultgren, (November 16, 1886–May 15,1974) was a swedish metallurgist. Hultgren is perhaps most famous for his work on tungsten steels, and the transformation of Austenite.

Hultgren was born in Kalmar, Sweden and studied metallurgy at the Royal Institute of Technology in Stockholm, Sweden. Following his MSc and some temporary positions in teaching, industry and a research vistit in Berlin under Prof. H. Hanemann, Hultgren joined SKF company in Gothenburg. In 1920 he published his monograph on tungsten steels. Later, in 1937 he became the first Metallography Professor at the Institute.

His focus was combine experimental methods and metallographic observation with theoretical reasoning, in a deductive way.
