脆韧转变 meaning in English
brittle tough transition
brittle-ductile transition
Examples
- Eoc and caco3 were combined to toughen and reinforce pp to study the effect of factors such as the composition , the diameter and shape of filler , the nature of elastomer , dispersing morphology and matrix type on the properties of pp / eoc / caco3 composites
结合起来增韧增强聚丙烯，研究了组成比、填料粒径及形状、弹性体性质、分散形态和基体类型等一系列因素对pp用occaco3复合材料性能的影响，揭示该体系发生脆韧转变的基本条件是l人（ 。 - The impact behaviors of pp / eoc and pp / caco3 were compared . the toughening mechanisms of pp / eoc and pp / caco3 systems are firstly proved to agree well with wu ' s percolation theory . the essential condition occurring brittle - tough transition in two binary systems is that the matrix ligament thickness ( l ) is lower than the critical matrix ligament thickness ( lc ) which is approximate to 0 . 095 ? m
比较ppffioc和ppcacos二体系的增韧行为，发现加入eoc和cacos都能增韧pp ，首次验证了新型弹性体eoc和无机刚性粒子cacos增韧pp的机理符合wu氏逾渗理论，二体系发生脆韧转变的基本条件是基体带厚度l小于临界基体带厚度人（ 。 - The results revealed that the essential condition occurring brittle - tough transition in such ternary system was l ? lc ( ? 0 . 095 ? m ) , and the effect of above factors on the impact behavior followed percolation mechanism which indicated that it was some reasonable using lc as single parameter criterion of brittle - tough transition of pp / eoc / caco3 composites . the micro - deformation model at different dispersing morphology was then proposed
