Developing focus and lead- ership in these and similar aspects of materials research and building on its legacy will enable MMT to retain its top posi- tion in the rankings of materials and metallurgical journals. Key Dates in Met Trans History: • 1970— Transactions Quarterly of the American Society for Metals and Transactions of the Metallurgical Society of AIME merge to launch Metallurgical Transactions, with Gerhard Derge as Editor • 1978 – Edwin Ruh becomes Editor • 1984 – Tony Thompson becomes Editor • 1975—Growing journal splits into Metallurgical Transactions A, dealing with physical metallurgy and materials science, and Metallurgical Transactions B, dealing with process metallurgy and materials processing science • 1987 – David Laughlin becomes Principal Editor • 1994 – In recognition of expanding areas of interest, journal titles change to Metallurgical and Materials Transactions A (MMTA) and Metallurgical and Materials Transactions B (MMTB) • 2007 – Springer partnership begins. All issues of the journals back to 1970 are posted online and made available free of charge to ASM and TMS members as a member benefit. • 2016 – David Laughlin ends 30-year tenure as Principal Editor and is succeeded by Tresa M. Pollock “MMT ’S CORE LEGACY IS METALLURGY AND I THINK IT WILL STAY AS THE SOLE SCIENTIFIC JOURNAL IN THIS FIELD, ESPECIALLY MMTB .” — SEETHARAMAN 50 Years of High Impact Research* The first issue of Metallurgical Transactions appeared in 1970, with Gerhard Derge of the Carnegie Institute of Technology as Editor. The journal formed as a result of the merger of Transactions Quarterly of the American Society for Metals and Transactions of the Metallurgical Society of AIME. In 1975 the journal split into Metallurgical Transac- tions A and B , specializing in physical and process metal- lurgy, respectively. The non-profit MMT journals are jointly managed by ASM and TMS and support a broad range of professional activities within the societies. MMT serves the entire international community, with broad geograph- ical representation on the editorial board. It is interesting to consider the ten most highly cited papers of 1970, which will be familiar to many: • “Dispersion Strengthened Superalloys by Mechanical Alloying,” J.S. Benjamin, doi: 10.1007/BF03037835 • “The Relation Between Polycrystal Deformation and Single-Crystal Deformation,” U.F. Kocks, doi: 10.1007/ BF02900224 • “The E ect of Carbide and Nitride Additions on the Heterogeneous Nucleation Behavior of Liquid Iron,” B.L. Bramfitt, doi: 10.1007/BF02642799 • “The Influence of Alloying, Temperature, and Related E ects on the Stacking Fault Energy,” P.C.J. Gallagher, doi: 10.1007/BF03038370 • “The Temperature Dependence of the Flow Stress of the γ ’ Phase Based upon Ni 3 Al,” P.H. Thornton, R.G. Davies, and T.L. Johnston, doi: 10.1007/BF02819263 • “The Origin of Freckles in Unidirectionally Solidified Castings,” S.M. Copley, A.F. Giamei, S.M. Johnson and M.F. Hornbecker, doi: 10.1007/BF02643435 • “The Martensite Phases in 304 Stainless Steel,” P.L. Mangonon and G.
