PURPOSE: To manufacture an article having fine structure and prescribed thickness by laminating a light-gate strip which is quickly cooled by contact of a molten metal alloy with a cooling body under movement by coiling, etc. and subjecting such strip to pressurizing and further compressing under heating to have a specific occupying rate or above.

CONSTITUTION: A molten metallic alloy is brought into contact with, for example, a cooling body under rotation and the cooling rate is controlled to about ≥104°C/sec to form a light-gage strip consisting of ≤0.1mm fine crystal grains. Such light-gage strip is coiled on, for example, a coiler and is taken up then the strip is laminated and pressurized to a tentative press contactstate having about ≥70% space factor such article is heated to the temp. below the m.p. and pressurized to have about ≥98% space factor such working is preferably accomplished in an inert gaseous or vacuum atmosphere. The article having the fine structure and prescribed thickness is produced more inexpensively than with a powder method, etc. by such stage.
