PURPOSE:To obtain the subject Al-based alloy to which the working such as extrusion and pressing is capable and having high corrosion resistance, high hardness and high tensile strength by specifying the compositional limiting value and regulating the volume rate of amorphousness. CONSTITUTION:The molten metal 3 of an alloy contg. the compsn. expressed by the formula is charged to a quartz tube 1, is set directly upon a roll 2 made of copper which revolves at the high speed, is sprayed from a pore 5 of the quartz tube 1 under the pressurizing of an Ar gas and is subjected to quenching and solidifying to prepare the alloy having a quenched thin zone 4 which contains at least 50vol.% amorphousness. By this constitution, since the alloy shows a super plastic phenomenon near the recrystallization temp., can easily be subjected to working such as extrusion and pressing and has high corrosion resistance, high hardness and high tensile strength, it can be offered to wide range of application as high corrosion-resistant and high tensile material or the like. |
