Alloys which form metallic glass upon cooling below the glass transition temperature at a rate appreciably less than 106 K/s comprise beryllium in the range of from 5 to 52 atomic percent and at least one early transition metal in the range of from 30 to 75% and at least one late transition metal in the range of from 2 to 52%. A preferred group of metallic glass alloys has the formula (Zr1-XTiX)a(Cu1-yNiy)bBec. Generally, a is in the range from 30 to 75% and the lower limit increases with increasing x. When x is in the range of from 0 to 0.15, b is in the range of from 5 to 52%, and c is in the range of from 6 to 47%. When x is in the range of from 0.15 to 0.4, b is in the range of from 5 to 52%, and c is in the range of from 5 to 47%. When x is in the range of from 0.4 to 0.6, b is in the range of from 5 to 52%, and c is in the range of from 5 to 47%. When x is in the range of from 0.6 to 0.8, b is in the range of from 5 to 52%, and c is in the range of from 5 to 42%. When x is in the range of from 0.8 to 1, b is in the range of from 5 to 52%, and c is in the range of from 5 to 30%. Other elements may also be present in the alloys in varying proportions.
