Abstract
A high-modulus iron-based alloy containing at least one boride dispersed in an iron or iron-alloy matrix. The boride may be one of a Group IVa element, or a complex boride of at least one Group Va element and iron. A mixture of an iron or iron-alloy powder and a powder of at least one boride containing a Group IVa or Va element is compacted and sintered to make a shaped high-modulus iron-based alloy product.
Claims19
An iron-based alloy consisting essentially of:
- a matrix formed of iron or an iron alloy;
- and
- at least one boride selected from the group consisting of borides of Group IVa elements titanium, zirconium or hafnium and complex borides of at least one Group Va element vanadium, niobium or tantalum, and iron, said at least one boride being dispersed in said matrix, and wherein said at least one boride is in the form of fine particles having a diameter of not more than 100 microns, and dispersed uniformly in said matrix.
An iron-based alloy comprising:
- (a) a matrix comprising iron or an iron alloy;
- and
- (b) at least one compound selected from the group consisting of
- (i) borides of Group IVa elements and
- (ii) complex borides of at least one Group Va element and iron,
- wherein said at least one compound is dispersed in said matrix.
