چکیده انگلیسی
Glass formation, thermal stability, elastic moduli and mechanical properties of La-Al-C bulk metallic glasses (BMGs) were investigated. The BMGs of La57.5Al32.5C10, La60Al30C10, and La62.5Al27.5C10 with the maximal diameters up to 3Â mm can be synthesized. Compared with other La-based glassy systems, like La-Al-(Co, Ni, Cu), the La-Al-C BMGs with the similar La concentration exhibit higher glass transition temperatures (507-577Â K) and elastic constants. The La-Al-C BMGs with the unusual Tg and elastic moduli fill a gap in thermal and elastic properties between light rare-earth-based BMGs and heavy rare-earth-based ones. The compressive yield strength of La57.5Al32.5C10 BMG reaches to â¼1.1Â GPa, higher than that of other reported La-based BMGs. The ternary BMGs with simple element constituent, high glass-forming ability and superior mechanical properties are significant for fundamental research as model materials.
