    摘要: A process of fabricating a monolithic working component for magnetic heat exchange is disclosed. The process includes mixing two or more portions comprising amounts of La, Fe, Si and at least one of T and R suitable to produce a La1-aRa(Fe1-x-yTySix)13Hz phase, wherein T is at least one element from the group consisting of Mn, Co, Ni and Cr and R is at least one element from the group consisting of Ce, Nd, Y and Pr. The amount of T, R, and Si is selected for each of the two or more portions to provide the two or more portions with differing Curie temperatures and, preferably, a density, d, within a range of ±5% of an average density, dav, of a total number of portions. The process includes heat treating a single monolithic green body formed from two or more precursor powder mixtures to produce a single monolithic working component.

    摘要: An article for magnetic heat exchange includes a functionally-graded monolithic sintered working component including La1-aRa(Fe1-x-yTyMx)13HzCb with a NaZn13-type structure. M is one or more of the elements from the group consisting of Si and Al, T is one or more of the elements from the group consisting of Mn, Co, Ni, Ti, V and Cr and R is one or more of the elements from the group consisting of Ce, Nd, Y and Pr. A content of the one or more elements T and R, if present, a C content, if present, and a content of M varies in a working direction of the working component and provides a functionally-graded Curie temperature. The functionally-graded Curie temperature monotonically decreases or monotonically increases in the working direction of the working component.
