Abstract
Abstract A method of making a substantially ordered alloy which involves providing a metal base consisting of at least one of the ingredients of the desired alloy, depositing a thin metal layer on the base, the metal layer containing the remaining constituents of the desired alloy, and heating the metal base and the deposited metal layer at a temperature below the order-disorder transformation temperature of the ordered alloy to be formed to thereby cause the ordered alloy to be produced by diffusion.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
A method for making a substantially ordered alloy containing at least a first metallic element and a second metallic element comprising the steps of: (a) providing a solid, imperforate metal base consisting of at least said first metallic element, (b) depositing a thin metal layer on said base, said metal layer consisting of at least said second metallic element, said second metallic element being capable of forming an ordered alloy with said first metallic element, said metal layer being not in excess of 10 microns in thickness, and (c) heating said metal base and the deposited metal layer at a temperature below the order-disorder transformation temperature of the ordered alloy to be made for a sufficient length of time to cause diffusion of said deposited metal into said metal base and formation of a continuous layer of ordered alloy between the two metals.
Claim 2
Independent Claim
143 words
A method for making a substantially ordered alloy containing at least a first metallic element and a second metallic element comprising the steps of: (a) providing a solid, imperforate metal base consisting of at least said first metallic element, (b) depositing a thin metal layer on said base, said metal layer consisting of at least said second metallic element, said second metallic element being capable of forming an ordered alloy with said first metallic element, said metal layer being not in excess of 10 microns in thickness, and (c) heating said metal base and the deposited metal layer at a temperature below the order-disorder transformation temperature of the ordered alloy to be made for a sufficient length of time to cause diffusion of said deposited metal into said metal base and formation of a continuous layer of ordered alloy between the two metals.
Claim 3
Dependent Claim
21 words
A method of making an ordered alloy as claimed in claim 1, in which said ordered alloy is a binary alloy.
Claim 4
Dependent Claim
35 words
A method of making an ordered alloy as claimed in claim 2, in which said metal base consists solely of the first metallic element and said metal layer consists solely of the second metallic element.
Claim 5
Dependent Claim
23 words
A method of making an ordered alloy as claimed in claim 1, in which the depositing step is carried out by vapor deposition.
Claim 6
Dependent Claim
22 words
A method of making an ordered alloy as claimed in claim 1, in which said depositing step is carried out by plating.
Claim 7
Dependent Claim
24 words
A method of making an ordered alloy as claimed in claim 1, in which said depositing step is carried out by chemical vapor deposition.
Claim 8
Dependent Claim
22 words
A method of making an ordered alloy as claimed in claim 1, in which said depositing step is carried out by sputtering.
Claim 9
Dependent Claim
27 words
A method of making an ordered alloy as claimed in claim 1, in which said deposited metal layer consists of two elements with a predetermined atomic ratio.
Claim 10
Dependent Claim
25 words
A method of making an ordered alloy as claimed in claim 1, in which said deposited layer consists of two layers of different metallic elements.
