primary crystal meaning in English
初晶石墨
初生晶体
初析晶
Examples
- Used solid - liquid reaction synthesis technology and stirring casting and metal mold chilling processing , al3fe particles and al3fe + al2o3 particles reinforced pure al matrix in - situ composites are fabricated . the metallography analysis shows that the intermetallic al3fe exhibits two kinds of crystalline state - primary crystal al3fe and eutectic crystal al3fe - in al + fe reaction synthetical al matrix in - situ composites
利用固-液反应合成技术和搅拌技术，并结合金属型激冷铸造工艺，制备出了al _ 3fe粒子、 al _ 3fe粒子+ al _ 2o _ 3微粒强化的纯al基原位复合材料。 - The eutectic crystal al3fe often is " needle " shape or short line shape but the shape of primary crystal al3fe is relative to the adding amount of fe powder and the temperature of heat preservation stirring . while the adding amount of pure fe powder is few and the temperature of heat preservation stirring is higher than the temperature of liquidus of al - fe binary alloys equilibrium phase diagram , the reaction synthetical primary crystal al3fe exhibits short worm shape
加入量少，保温搅拌温度在al - fe二元合金液相线以上，则形成的初晶al _ 3fe呈短蠕虫状； fe加入量大，保温温度在液相线以上，初晶al _ 3fe以平面方式生长，复合材料中的初晶al _ 3fe呈块状或粒状，尺寸较大( 10 m以下) 。
