Bulk Metallic Glasses
LMPT’s main research area is “bulk metallic glasses” (BMGs). These are materials which can be produced with an amorphous microstructure via cooling from the melt. Here we search for compositions where cooling rates of less than 1000 K/s are sufficient to generate metallic glasses. Such low critical cooling rates enable the production of bulk parts with thicknesses ranging from millimeters to centimeters. They also facilitate very interesting experiments in the deeply undercooled liquid range.
A general overview of bulk metallic glasses is provided in this book chapter (PDF, 4.7 MB).
