The results suggest that the high glass forming ability of La- based metallic glasses would be closely related to the slow atomic rearrangements in liquid melts. Moreover, the strong glass former has relatively dense atomic packing and also small density change in the liquid state. ![]() It is demonstrated that the strong glass forming liquid not only has the small thermal expansion coefficient but also shows the slow variation rate. Thermal behaviors of liquid La- based bulk metallic glasses have been measured by using the dilatometer with a self-sealed sample cell.

Thermal behaviors of liquid La- based bulk metallic glassesĮnergy Technology Data Exchange (ETDEWEB) ![]() It is expected that the Tm- based glasses with the unique properties are appropriate candidates for studying some important issues in BMGs The reasons for the different properties between the Tm- based and other RE- based BMGs are discussed. Compared with other known rare-earth (RE) based BMGs, Tm- based BMGs show features of excellent glass formation ability, considerable higher elastic modulus, smaller Poisson's ratio, high mechanical strength, and intrinsic brittleness. We report the formation and properties of a thulium- based bulk metallic glass (BMG). In this study, bulk glasses have been obtained in Zr based multicomponent alloy by induction melting these alloys in silica crucibles and casting these in form of rods 3 and 6 mm in diameter in a copper mould Metallic glasses have come into prominence in recent times because their nanocrystalline atomic arrangement imparts many useful and unusual properties to these metallic solids.
