However, the above standards do not standardize the actual operation method, so that the test method of pulling the thin strip with a bar of 3 mm in diameter and manually can still meet the above standard specifications, so that it is easy to test different methods. Causes test errors.

Therefore, it is necessary to provide an innovative and progressive amorphous thin strip ductility automatic test device to solve the above problems.

The invention provides an amorphous thin strip ductility automatic testing device, comprising: a body having a slot, the slot comprising a front slot portion, an intermediate slot portion and a rear slot portion, wherein the intermediate slot portion is located in the front slot Between the portion and the rear groove portion; a winding shaft disposed in the front groove portion for winding an amorphous ribbon; a winding shaft disposed in the intermediate groove portion for winding the amorphous portion a thin strip; and a ductile test rod disposed in the rear groove portion for ductility testing of the amorphous ribbon.

The invention can automate and standardize the ductility test of the amorphous ribbon, thereby reducing the error caused by the artificial measurement.
