METHOD FOR IMPROVING METALLIC STRUCTURE OF SI-CONTAINING MAGNESIUM ALLOY

Title:

METHOD FOR IMPROVING METALLIC STRUCTURE OF SI-CONTAINING MAGNESIUM ALLOY

Document Type and Number:

Japanese Patent JPH06279889

Kind Code:

A

Abstract:

PURPOSE: To refine Si compounds in an Mg alloy and improve its forgeability and mechanical properties by adding a specified amt. of Sr to an Mg alloy contg. a specified amt. of Si.

CONSTITUTION: An Mg alloy contg. ≤1.5% Si is added with 0.005 to 0.2% Sr. In this way, fine lumpy Mg2Si compounds can be produced in regardless of the cooling rate, and favorable mechanical properties and forgeability free from hot cracking can be obtd. The amt. of Sr to be added is regulated to ≥0.005%, and since if it exceeds 0.2%, the effect can not be expected, so that the above range is restricted.
