ARTICLE COMPRISING AT LEAST ONE MAGNETOCALORICALLY ACTIVE PHASE AND METHODE OF WORKING AN ARTICLE COMPRISING AT LEAST ONE MAGNETOCALORICALLY ACTIVE PHASE

摘要

A method of working an article (1; 10; 20) comprises providing an article (1: 10; 20) comprising at least one magnetocalorically active phase having a magnetic phase transition temperature Tc and removing at least one portion of the article (1; 10; 20) whilst the article (1; 10; 20) remains at a temperature above the magnetic phase transition temperature Tt. or below the magnetic phase transition temperature Tc.
