The invention provides a kind of manufacture method of ultramicro-crystal alloy strip, it is the method manufacturing following ultramicro-crystal alloy strip, described ultramicro-crystal alloy strip has the tissue of the ultra tiny crystal grain being dispersed with average grain diameter 1 ~ 30nm in noncrystalline parent phase with the ratio of 5 ~ 30 volume %, described method is as follows: on the chill roll rotated, carry out chilling by being sprayed by alloy molten solution, before starting to reel wound, form following strip and be easy to winding, even if this strip has the toughness being bent to below bending radius 1mm and also not rupturing, the formation condition of described strip is changed after starting to reel wound, to allow to the tissue obtaining the ultra tiny crystal grain being dispersed with average grain diameter 1 ~ 30nm in noncrystalline parent phase with the ratio of 5 ~ 30 volume %. |
