Abstract

Most often when one metal in a subgroup has a higher melting point MP than another with a higher atomic number, then its Young's modulus also is higher (e.g. Be). However there are exceptional cases when for some metals (e.g. Mg) the melting point is lower and the E-modulus is higher than for the next metal with a higher AN in the same subgroup (e.g. Ca). This is explained by considering the product of density and specific heat rCp (cal/cm3) for metals with low MP and high heat required for heating to the MP.

Kurzfassung

Wenn ein Metall einer Untergruppe der Periodischen Tabelle eine höhere Schmelztemperatur besitzt, dann hat es meistens auch einen höheren Elastizitätsmodul, wie zum Beispiel Beryllium. Es gibt aber besondere Fälle, in denen ein Metall mit niedriger Schmelztemperatur einen höheren E-Modul aufweist, wie zum Beispiel Magnesium. Der Verfasser erklärt dies mit höheren Wärmewer- ten (rCp) und (W-L) während des Erwärmens bis zur Schmelztemperatur MP, die im Vergleich mit dem nächsten Metall Calcium auftreten.

Prof. Dr. Alfred Buch studied Mechanical Engineering and Materials Science in Warsaw, Lvov and St. Petersburg. He received the degrees M. Sc. in 1943 and Dr. Sc. Tech. in 1949. From 1956 to 1968 he was head of the Materials Strength Department of an industrial research institute in Warsaw. From 1969 until his retirement, he worked in the Aeronautical Department of the Technical University Technion in Haifa, Israel. He is the author of many publications in the field of fatigue and materials science. Among his cooperations with German researchers, he has frequently worked together with the Institut für Werkstofftechnik and the Laboratorium für Betriebsfestigkeit in Darmstadt.
