Title:
ROLLING METHOD FOR SENDUST ALLOY
Document Type and Number:
Japanese Patent JPS5791804
Kind Code:
A
Abstract:

PURPOSE: To permit rolling by the use of a special device without generation of cracking by coating a cast ingot of a sendust alloy with a metal of good hot workability at specific thickness, and subjecting the same to rolling at above specific draft.

CONSTITUTION: A cast ingot 2 of a sendust alloy is coated with a metal 5 of good hot workability, for example, alumina powder. This coating layer is formed to the thickness at which t/n and l/n are ≥1/3. (n); the thickness of the sendust alloy mm, (t); the thickness of the side plate coating the sendust alloy mm, (l); the plate thickness of the top and bottom surfaces coating the sendust alloy mm. The cast ingot of the sendust alloy after coated with the metal is heated to 900W 1,230°C, and is subjected to rolling at above 50% draft.
