ABSTRACT:
A method of treating a metallurgical object containing metastable featureless regions adversely affecting toughness, comprising heating the object for transforming the regions at least sufficiently out of their metastable state to improve toughness.
A method of treating metal particles containing metastable featureless regions which adversely affect toughness when the particles are bonded together to form a metallurigcal object, comprising heating the particles for transforming the regions at least sufficiently out of their metastable state to improve toughness in metallurgical objects formed by bonding the particles together.
