【発明の名称】ベリリウムを含有する金属ガラスの形成
Document Type and Number:
Japanese Patent JPH08508545
Kind Code:
A
Abstract:
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 2 to 47 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 5 to 62%. 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 62%, 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 62%, and c is in the range of from 2 to 47%. When x is in the range of from 0.4 to 0.6, b is in the range of from 5 to 62%, and c is in the range of from 2 to 47%. When x is in the range of from 0.6 to 0.8, b is in the range of from 5 to 62%, and c is in the range of from 2 to 42%. When x is in the range of from 0.8 to 1, b is in the range of from 5 to 62%, and c is in the range of from 2 to 30%. Other elements may also be present in the alloys in varying proportions.
