Title:
FE-NI-BASED ALLOY METAL FOIL WITH EXCELLENT THERMAL STABILITY, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/104871
Kind Code:
A1
Abstract:
An Fe-Ni-based alloy metal foil with excellent thermal stability, and a preparation method therefor are disclosed. One aspect of the present invention provides an Fe-Ni-based alloy metal foil having excellent thermal stability, prepared by an electroforming (EF) method and having a thickness of 100 μm or less (except 0 μm), wherein the metal foil comprises 34-46 wt% of Ni and the balance of Fe and inevitable impurities and has a thermal stability ratio which is 30 ppm or less and represented by the following mathematical formula 1.
[Mathematical formula 1]
Thermal stability ratio = (L-L0)/L0
(wherein L0 is the length of the metal foil (surface temperature 30°C) before heat treatment, and L is the length of the metal foil after heat treatment and is defined as the length of the metal foil when the surface temperature of an alloy is increased from 30°C to 300°C at a speed of 5°C/min, maintained at 300°C for five minutes, and then cooled to a surface temperature of 30°C at a speed of 5°C/min.)
