利用力学实验及EBSD等微观分析手段,研究表征高钢级管线钢的特征参数,并探讨其对强韧性的影响。 更多例句>> 4) strength-toughness 强韧性 1. The dynamicstrength-toughnessof 9Cr-lMo-V-Nb-N steel; 9Cr-1Mo-V-Nb-N钢的动力强韧性 2. In view of the improper matching of thestrength-toughnessfor domest...
All the results demonstrate that biological materials choose different interface structures to meet the requirements of strength and toughness matching, based on the differences in the mechanical properties of soft and hard phases. Such a selection mechanism provides a direct reference for the optimal ...
proper amount of alloy elements such as Cr, Mo, Mn and Ni are added to increase the strength of the material and microalloyed elements such as V, Nb, Ti and the like are added as auxiliary elements so as to refine the particle size and improve the strength-toughness matching of steel pi...
With the addition of Mo, the highest combustion temperature decreased and the matching degree between ceramic particles and Ni binder was improved, which lead to the decrease in the porosity of cermets and the refinement of ceramic particles. The fabricated TiB2–Ti(C,N)–Ni cermet with 2 wt...
2.In view of the improper matching of thestrength-toughnessfor domestic petroleum drill pipe sub,the influence of the chemical compositions and metallurgical quality of 37CrMoE steel used for drill pipe sub on its mechanical properties,as well as the effect of the metallurgical quality on the har...
The fracture properties and behaviors of mathching strength and toughness of 16Mn welded joints are studied and analysed by means of the miniature deep notch test.The results show that under the conditions of high stress plastic fractures and high stress brittle fractures,the fracture strength of 16...
This indicates that at the interface between the GNS and the matrix, bonding was so strong that the GNS broke preferentially over the matrix during the stretching process, which resulted in effective load-transfer and hence good strong plasticity matching of the material.
