Abstract
The invention discloses a kind of heat resistance casting magnesium alloys, are grouped as by the group of following weight percent content：Silicon 0.5 2%, aluminium 2.5 5.5%, zinc 5 8%, bismuth 0.2 0.5%, manganese 0.1 0.5%, gadolinium 3 5%, calcium 0.2 1.5%, total amount are less than 0.02% impurity, and surplus is magnesium.The present invention effectively raises the heat resistance of magnesium alloy by optimized alloy ingredient and proportioning, and the comprehensive mechanical property of cast Mg alloy with high strength of the invention is apparently higher than the cast magnesium alloy reported at present.
Description
Technical field
The present invention relates to casting technology fields, more particularly to a kind of heat resistance casting magnesium alloy.
Background technology
With the fast development of global economy, how to reduce energy consumption, improve resource utilization, reduce environmental pollution with
And it is the very urgent problem that the whole mankind is faced to save limited resources, and the light weight of product turns to and solves the problems, such as the offer one
A very effective approach.Magnesium alloy is since, specific strength low with density and specific stiffness are high, damping characteristics are good, electromagnetism
The advantages that shielding is good, machining property is excellent is known as " green engineering material of 21 century ", is a kind of great exploitation value
The resource of value is widely used in the fields such as auto industry, communication electronics and aerospace.But it is strong due to magnesium alloy
Degree is not high, and heat resistance is poor, limits its scope of application.Therefore, the intensity and heat resistance for improving magnesium alloy make it have good
Comprehensive performance, be novel magnesium alloy exploitation hot spot.
Invention content
In order to make up the defect of prior art, the present invention provides a kind of heat resistance casting magnesium alloy.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of heat resistance casting magnesium alloy is grouped as by the group of following weight percent content：Silicon 0.5-2%, aluminium 2.5-5.5%, zinc
5-8%, bismuth 0.2-0.5%, manganese 0.1-0.5%, gadolinium 3-5%, calcium 0.2-1.5%, total amount are less than 0.02% impurity, and surplus is magnesium.
The present invention has the advantages that：
The present invention effectively raises the heat resistance of magnesium alloy, high intensity of the invention casting by optimized alloy ingredient and proportioning
The comprehensive mechanical property for making magnesium alloy is apparently higher than the cast magnesium alloy reported at present.
Specific implementation mode
With reference to embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention,
It is not limitation of the invention.
Embodiment 1
A kind of heat resistance casting magnesium alloy is grouped as by the group of following weight percent content：Silicon 1.2%, aluminium 3.8%, zinc 5-8%, bismuth
0.3%, manganese 0.3%, gadolinium 4%, calcium 0.8%, total amount are less than 0.02% impurity, and surplus is magnesium.
Embodiment 2
A kind of heat resistance casting magnesium alloy is grouped as by the group of following weight percent content：Silicon 0.5%, aluminium 2.5%, zinc 5%, bismuth
0.2%, manganese 0.1%, gadolinium 3%, calcium 0.2%, total amount are less than 0.02% impurity, and surplus is magnesium.
Embodiment 3
A kind of heat resistance casting magnesium alloy is grouped as by the group of following weight percent content：Silicon 2%, aluminium 5.5%, zinc 8%, bismuth
0.5%, manganese 0.5%, gadolinium 5%, calcium 1.5%, total amount are less than 0.02% impurity, and surplus is magnesium.
Embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention, as long as skill obtained in the form of equivalent substitutions or equivalent transformations
Art scheme should all be fallen within the scope and spirit of the invention.
