Abstract

The present invention relates to a kind of ultra-toughness metal screws, mainly it is made of the following component being calculated in mass percent：Al9.2 11.9%, Mo4.4 12.5%, Mg8.5 13.4%, Bi0.5 0.8%, Zr3.1 7.7%, Ce0.3 0.5%, Ni0.02 0.05%, Mn0.35 0.48%, nanometer nbr carboxyl terminal 0.3 0.8%, surplus are iron.The present invention can realize prepared by the ultra-toughnessization of metal screws by adding nanometer nbr carboxyl terminal, substantially increase the elongation at break and impact strength of screw.

Description

A kind of ultra-toughness metal screws
Technical field
The present invention relates to metal product manufacture field, more particularly to a kind of ultra-toughness metal screws.
Background technology
Screw is the physics and mathematical principle of the inclined-plane circular rotating and frictional force using object, is fastened by easy stages The instrument of implements parts.Screw is the general saying of fastener, daily pet phrase.Screw is work indispensable in daily life Industry necessity：The minimum screw that such as camera, glasses, clock and watch, electronics use；TV, electric product, musical instrument, furniture etc. General screw；As for engineering, building, bridge then using large-scale screw, nut；Traffic tool, aircraft, electric car, automobile etc. are then It is used in combination for big primary screw.Screw industrially bears vital task, as long as there is industry on the earth, then the function of screw is eternal It is important.Screw is the joint invention in people's production and living over the past thousands of years, and from the point of view of application field, it is the first big of the mankind Invention.
With the continuous progress of science and technology, the requirement of higher is proposed to the metal material performance for preparing screw.
The content of the invention
In order to solve the above-mentioned technical problem, there is provided a kind of toughness super large, the wider array of metal screws of application range prepare alloy, The present invention provides following technical scheme：
A kind of ultra-toughness metal screws, are made of the following component being calculated in mass percent：Al9.2-11.9%, Mo4.4- 12.5%th, Mg8.5-13.4%, Bi0.5-0.8%, Zr3.1-7.7%, Ce0.3-0.5%, Ni0.02-0.05%, Mn0.35- 0.48%th, nanometer nbr carboxyl terminal 0.3-0.8%, surplus are iron.
Further, it is made of the following component being calculated in mass percent：Al10.5%, Mo8.4%, Mg11.9%, Bi0.68%, Zr5.4%, Ce0.4%, Ni0.035%, Mn0.43%, nanometer nbr carboxyl terminal 0.65%, surplus are Iron.
Further, it is made of the following component being calculated in mass percent：Al9.2%, Mo4.4%, Mg8.5%, Bi0.5%, Zr3.1%, Ce0.3%, Ni0.02%, Mn0.35%, nanometer nbr carboxyl terminal 0.3%, surplus are iron.
Further, it is made of the following component being calculated in mass percent：Al11.9%, Mo12.5%, Mg13.4%, Bi0.8%, Zr7.7%, Ce0.5%, Ni0.05%, Mn0.48%, nanometer nbr carboxyl terminal 0.8%, surplus are iron.
The beneficial effects of the present invention are：The ultra-toughness of metal screws can be realized by adding nanometer nbr carboxyl terminal Change and prepare, substantially increase the elongation at break and impact strength of screw.
