就要毕业了,论文的摘要要用英文翻译,我的水平太有限了,翻译出来老有中国味,请高手帮忙翻译一下,谢谢了!
"本文研究了抗磨损能力较好的C-Cr-Mo-V系合金的组织性能,试验采用手工搓制的方法制作了多种合金配比不同的焊条,用交流电弧焊机将焊条堆焊到试板上,然后对堆焊试样进行了洛氏硬度测试、组织观察及成份检测。通过对每种试样的硬度、组织及成份的分析,最后得出合金元素对该堆焊合金耐磨性能的影响规律并获得最佳的合金成份配比。
C-Cr-Mo-V堆焊层金属基本上都是低碳或高碳马氏体及奥氏体,并且基体中存在网状或块状碳化物组织及呈弥散状分布的碳化物颗粒,提高了基体表面的耐磨性。在冲击过程中堆焊层金属滑移带中出现了高密度的位错,这些高密度的位错,使晶体滑移受阻,致使材料得到强化;同时大量的位错缠结并钉扎在晶界,最终导致位错运动和晶体滑移的阻力大大增加,这是材料形变后宏观硬度增大的主要原因。

"It is the organization performance of the alloy that this text has studied C-Cr-Mo-V which resists the wearing and tearing with better ability , have tested and made different welding rods of many kinds of alloy matching by rubing with the hands and making by hand, on piling and welding to and trying the board the welding rod by exchanging the electric arc welder , then carried on Rockwell hardness in piling and welding samples and is tested , organizes observing and compositions to measure . Pass the hardness of each kind of sample correctly, the organization and analysis of compositions, must produce the alloying element to piling the influence law which weld the wear-resisting performance of alloy and obtaining the best alloy composition matching finally.
It is all low carbon or horse's body and body of high carbon basically that C-Cr-Mo-V piles and welds one layer of metal, and there is netted or cubic carbide that organizes and presents the carbide particle that the disperse form is distributed in the body in the base , wearability of improving the base the body surface. It is wrong to pile and weld the location where one layer of metal has slipped and moved and presented the high density while taking in the course of assaulting, the location of these high density makes the crystal slip and move and is obstructed, cause materials to be strengthened by mistake; A large number of location tangles is it is it in brilliant circle , cause location sport and crystal obstruction moved to slip increase greatly by mistake finally to pitch to nail by mistake at the same time, this is the main reason that the macroscopical hardness increases after material deformation.

The research capacity of the wear-resistant alloys is better C-Cr-Mo-V organizational performance, the use of manual testing of the entire system to produce a variety of alloys limited means different welding rod, will be used to exchange electric arc butt welding rod Duihan to ban pop, and then a specimen of Duihan got hardness testing, component testing and observation organizations. By the hardness of each specimen, organization and content analysis, the final conclusion alloy elements Duihan alloy wear-resistance and the impact of limited access to the best alloy components. C-Cr-Mo-V Duihan layer metal are basically low or high-carbon martensite and austenite, and the presence of network or matrix organizations and a massive carbide dispersible warrants distribution carbide particles and increased matrix surface resistance to abrasion. Zuihan layer metal process in the impact zone, a high-density slip the wrong place, these high-density places wrong to crystal slip blocked, causing material reinforced; At the same time a large number of spaces in the wrong knot and nails Norte crystal community, and ultimately lead to the wrong place and crystal slip resistance movement greatly increased material deformation which is the main cause of increased macro hardness.
