KURDYUMOV, GEQRGII VYACHESLAVQVICH (Metallurgist) 

 G. V. Kurdyumov was born February 1, 1902. In 1926 he 

 graduated from the Leningrad Polytechnic Institute. He had 

 been working since 1925 at the Physico-Technical Institute of 

 the U. S.S.R. Academy of Sciences. In 1932 he began working at 

 the Dnepropetrovsk Physico-Technical Institute, and from 1932 

 to 1941 he taught at Dnepropetrovsk University. Kurdyumov 

 was appointed Director of the Institute of Metalworking and the 

 Physics of Metals of the Central Scientific Institute of Ferrous 

 Metallurgy (Moscow) in 1944. In 1939 he was elected Acade- 

 mician of the Ukrainian S.S.R. Academy of Sciences. He has 

 been a Corresponding Member of the U. S.S.R. Academy of 

 Sciences since 1946 and since 1953 an Academician. He was 

 awarded, in 1949, a Stalin Prize. 



Kurdyumov has studied the processes arising in the harden- 

 ing and tempering of steel and the phenomena of phase transfor- 

 mations, hardening, and diffusion in metals and alloys. To- 

 gether with N. Y. Gudtsov and N. Ya. Selyakov, he defined 

 (1926) the crystalline structure of martensite. The existence 

 of the regular orientation of the crystalline lattice of martensite
