Robert F. Mehl
Robert Franklin Mehl (born March 30, 1898 in Lancaster , Pennsylvania , † January 29, 1976 in Pittsburgh , Pennsylvania) was an American metallurgist at the Carnegie Institute of Technology .
Flour is assigned an important role in the transition from 19th century metallurgy to 20th century materials science and in the development of modern curricula in these subjects. He contributed significantly to the development of the Johnson-Mehl-Avrami-Kolmogorow equation , which describes phase transitions in nucleation .
Life
Mehl received a degree from Franklin & Marshall College and a Ph.D. from Donald P. Smith at Princeton University in 1924. in physical chemistry and metallurgy while lecturing at Juniata College . In 1925 he translated Gustav Tammann physical states from German into English. Mehl worked as a postdoctoral fellow with Theodore William Richards at Harvard University on a grant from the National Research Council .
From 1927 Mehl was the founding director of the department for physical metallurgy at the Naval Research Laboratory , where his collaboration with Charles S. Barrett on Widmanstätten structure was particularly fruitful. Together they improved methods of non-destructive material testing using X-rays . Mehl was involved in the American Institute of Mining and Metallurgical Engineers (AIME) and in the American Society of Metals (ASM), in which he made outstanding contributions to the contacts between scientific and industrial metallurgy.
In 1931/1932 Mehl worked in the research department of the American Rolling Mill Company in Middletown , Ohio , but in 1932 accepted a professorship in metallurgy at the Carnegie Institute of Technology (CIT), where he also became director of the Metals Research Laboratory . In 1935 he took over the management of the entire department for metallurgical technology.
In 1960 Mehl switched to the industry again and took on consulting activities for the United States Steel Corporation in Europe. In 1966 he returned to the United States, where he held short-term visiting professorships at the University of Delaware and Syracuse University .
In 1934 Mehl was elected as a fellow in the American Association for the Advancement of Science , in 1958 as a member of the National Academy of Sciences . He has received several awards from AIME and ASM, as well as four honorary doctorates. The Institute of Metals within the Minerals, Metals & Materials Society has presented an award for outstanding performance since 1922, which has been named after Robert Franklin Mehl since 1972.
Robert F. Mehl was married to Helen Charles since 1923. The couple had three children.
