In the nineties, there was an increasing scientific interest in the use of Sc as an alloying element in Al-alloys. This is well reflected in the ICAA-proceedings: in the 1990 conference in Beijing, China, only three papers were presented on Sc-containing Al-alloys. The number of Al-Sc related papers increased steadily during the 1990's to a level of between 20 and 30 for the last five conferences(ICAA7 through ICAA11).

The conferences:

ICAA, Charlottesville, Virginia, USA, 1986 No papers on Sc-containing Al-alloys. ICAA2, Beijing, China, 1990 Three papers on Sc-containing Al-alloys. ICAA3, Trondheim, Norway, 1992 Two papers on Sc-containing Al-alloys. ICAA4, Atlanta, Georgia, USA, 1994 Eight papers on Sc-containing Al-alloys.

ICAA5, Grenoble, France, 1996 11 papers on Sc-containing Al-alloys. ICAA6, Toyohashi, Japan, 1998 16 papers on Sc-containing Al-alloys. ICAA7, Charlottesville, Virginia, USA, 2000 22 papers on Sc-containing Al-alloys. ICAA8, Cambridge, United Kingdom, 2002 23 papers on Sc-containing Al-alloys.
