  • Joining of metals using a bulk amorphous intermediate layer
    Patent number: 5482580
    Abstract: Two pieces of metal are joined together using an amorphous metallic joining element. In the joining operation, the joining element is placed between the two pieces to be joined. The joining element and adjacent regions of the pieces being joined are given a joining processing sequence of heating to a joining temperature, forcing the two pieces together for a period of time, and cooling. The joining element has a composition that is amorphous after the processing is complete. The joining element composition is also selected such that, after interdiffusion of elements from the pieces being joined into the joining element during processing, the resulting composition is amorphous after cooling.

  • Method of forming berryllium bearing metallic glass
    Patent number: 5368659
    Abstract: Alloys which form metallic glass upon cooling below the glass transition temperature at a rate appreciably less than 10.sup.6 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 (Zr.sub.1-x Ti.sub.x).sub.a (Cu.sub.1-y Ni.sub.y).sub.b Be.sub.c. 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.
