The every field such as equipment and biomedicine, its yield annual growth is up to more than 25% always in recent years.It can be said that magnesium alloy is
Through as the third-largest metal material grown up after steel, aluminium alloy, be also most have in nonferrous materials exploitation and
One of metal material using future.But the shortcoming of magnesium alloy is also clearly, generally more than 120 DEG C, its elevated temperature strength
Can all be declined to a great extent with creep strength, seriously limit the range of application of magnesium alloy.Therefore a kind of heat-resisting magnesium alloy is needed
And the proposition of preparation method.
The content of the invention
A kind of heat-resisting magnesium alloy and preparation are provided the invention aims to solve above-mentioned the deficiencies in the prior art
Method.
To achieve these goals, a kind of heat-resisting magnesium alloy designed by the present invention, each component presses following quality percentage
Content is respectively Al：5-10%、Zn：0.5-2%、Mn：0.25-0.5%、Cu：0.05-0.1%、Si：0.2-0.5%、Co：0.05-
0.15%、Sm：0.05-0.15%、Ca：0.04-0.1%、Mo：0.02-0.05%；Balance of Mg and inevitable impurity, wherein,

Afterwards, Ca is combined generation CaSi with Si2Particle, is Mg2Si provides forming core source, makes Mg2The shape of Si is changed by thick man's shape
It is tiny polygon, so as to improve the mechanical behavior under high temperature of alloy, the content of Ca is 0.04-0.1% in this patent.
Mo contributes to the growth of Ca, and can improve the heat resistance of magnesium alloy, and the content of Mo is 0.02- in this patent
0.05%。
A kind of preparation method of heat-resisting magnesium alloy is as follows：Material rate according to magnesium alloy is well mixed, and then puts into
Melted in vacuum drying oven, be first warmed up to 750-800 DEG C, be incubated 30 minutes, then cooled to 700 DEG C -750 DEG C, then be incubated 20
