Al-Zn合金和SiCp/Al-Zn复合材料的激光重熔晶粒组织的对比研究表明 ,SiC颗粒对凝固初生相的生长具有阻碍作用。在颗粒尺寸较大和颗粒含量较高的条件下 ,激光熔池中会形成非外延生长的晶粒
A comparative study of laser recrystallization grain structure of Al-Zn alloy and SiCp / Al-Zn composites shows that SiC particles have an inhibitory effect on the growth of the solidified primary phase. Under the condition of larger particle size and higher particle content, non-epitaxial growth grains will be formed in the laser pool
