HIGH-STRENGTH AND HIGH-TOUGHNESS METAL AND PROCESS FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a high-strength and high-toughness metal which has strength and toughness each high enough to be put to practical use in expanded applications of magnesium alloys and also to provide a process for producing the same. SOLUTION: The high-strength and high-toughness metal is composed of a magnesium alloy comprising a crystal structure having an hcp-structure Mg phase and a long period layered structure phase. At least a part of the long period layered structure phase exists in a lamellar form with the hcp-structure Mg phase, and at least a part of the resultant lamellar structure existing in the lamellar form is curved or flexed.
