查询词典 dystectic

The results show t hat yttrium exists as the form of compound (Al2Y) in AZ31 magnesium alloy, and dystectic Al2Y as the heteromorphic nucleation emerges firstly in the cou rse of alloy precipitation, which refines the alloy's microstructure and obviou sly improves the mechanical properties at room and high temperature. The average grain size of AZ31 magnesium alloy containing Y is reduced by 35.82%. Tensile s trength, yield strength and elongation percentage reach 212 MPa, 147 MPa, and 7. 5% at room temperature respectively, and 117 MPa, 98 MPa, and 10.2% at 200 ℃ re spectively.

结果表明，Y在AZ31 镁合金中主要以块状Al2Y化合物形式存在；高熔点的Al2Y在合金凝固过程中首先析出，成为凝固的异质形核剂，从而细化了合金组织，改善了室温和高温力学性能；由于Y的强化，含Y AZ31镁合金平均晶粒尺寸降低幅度约为35.82 %；室温抗拉强度、屈服强度和延伸率分别为 212 MPa， 147 MPa和7.5%，200 ℃时分别为117 MPa， 98 MPa和10.2%。
