  • Abstract This thesis is divided into two parts. The main purpose of the first part is only to confirm further whether adding B can really improve the glass forming ability (GFA) and thermal stability. It is recently suggested that the addition of the even smaller sized B (0.08 nm) in the Mg65Cu25Y10 alloys to a certain level can further enhance GFA and provide the chance in fabricating larger bulk amorphous billet. The current study extends the concept of adding B to the Mg65Ni25Y10 based alloy, including the replacement of Ni by 1-5 at % (1, 3, and 5 at %) using the arc melting and melt spinning methods.
    The second part, this experiment drops magnesium element to 58 at% boldly, even lower, and the big element atom neodymium (Nd) improves to 11 at% or more upwards, different from everybody commonly used 65 at %, 25 at % , 10 at % as the main proportion composition , then to observe whether its supercooled liquid region
