基体组织 meaning in English
matrix structure
Examples
- It is shown that the high hardness and low thermal conductivity promote the formation of transformed asbs , and the deformed asbs will form if low hardness and high thermal conductivity are involved ; for steel with both high hardness and thermal conductivity , the transformed asbs will transform into deformed ones , due to that the fast heat conduction from high temperature asbs results in rapid temperature rise around and thus decreasing the hardness
研究结果表明：钢的高硬度和低热导率有利于形成相变带；反之，则倾向于形成变带；对于具有高硬度和高热导率的钢，由于高温相变带区域的热量迅速传递到周围的基体组织而使其温度升高、硬度降底，形成的相变带会向形变带转化。 - The results indicate that the fracture toughness is influenced markedly by the different base structure of vermicular east iron and by the form of graphite ; unlike steel , the fracture toughness of vermicular cast iron increases with the yielding strength , while drops drastically with the increase of ratio of graphite grain length to thickness
试验结果表明，蠕墨铸铁的断裂韧度受不同基体组织的影响比较明显；受不同石墨形态的影响显著，与结构钢不同，蠕墨铸铁的断裂韧度随材料的屈服强度增大而增大，随石墨颗粒的长厚比增加会急剧下降。 - Abstract : the structure and the properties of the grinding ball made of the composite cast iron have been researched in this paper . the result indicates that added trace boron and a proper quantity copper to this kind of composite cast iron can increase its quench - hardening ability , and raise its hardness and impact toughness
文摘:研究了一种复合铸铁磨球的组织和性能，结果表明，化学成分和淬火工艺对这种复合铸铁磨球的组织和性能有很大影响，微量的硼和适量的铜可以明显地提高磨球的淬透性，经过余热淬火得到贝氏体或马氏体基体组织，从而提高磨球的硬度和冲击韧性。 - For the fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w alloy system , the peak value of quenching appears in 950 - 1100 . the peak value increases with the increment of w . when the content of w is 2 % , the temperature of temper hardening is 550 . for the fe - 2 % c - 4 % v - 4 % mo - 5 % cr - 2 % w alloy , the appropriate quenching temperature can be controlled in 1000 1050 and the time of preserving heat is 12min
57 （原于百分比，人分析表明， mg的变质作用的产生是由于mg影响了合金元素的偏析，使得基体组织中合金元素含量增加，相当于使合金分配系数k更偏离于1 ，从而促进了形成缩颈、晶粒繁殖和成分过冷倾向。
