金属材料论文英文文献翻译

从文献中，这是众所周知的加入锰铝硅合金稳定下来后铁金属间化合物中的形式- alfesi相紧凑中文剧本形态，并减少B股alfesi相血小板 ， 4 - 7这项工作的结果证实了这些报道。图1表明增加 ％ ，锰（即mn/ ）有利于形成和统治的中文剧本阶段，在356和319合金含有 ％铁。但是，有几个血小板的B alfesi阶段仍然可以看到：在微观组织的319合金（图1 ） ，而没有明显的B alfesi血小板被认为是在微观结构的356合金后，除锰（图1B ）条。这意味着成效锰修改feintermetallics跌幅在319合金中含有铜，镁含量。这是在协议与先前的研究基地11si - 镁合金，而另外的Mn （锰/铁的比率 ）被发现是不够的，以避免的B alfesi相

GBT 24176-2009 金属材料 疲劳试验 数据统计方案与分析方法就是翻译BS ISO 12107-2003 Metallic materials — Fatigue testing — Statistical planning and analysis of data。你去下载吧

哥啊，用谷歌翻译不就行了吗，神马metal fatigue说的就是金属疲劳（断裂\损伤）的问题吗

第一个应该是某种加热标准，要查书。第二个是加工要求 ：淬火<扩> full hardening 淬透; 全淬硬; 全硬化<扩> full-hardened steel 全淬硬钢<扩> fully hardening steel 全硬淬透钢

洛阳理工学院 机电工程系 材料成型教研室Unit 3 Structure-Property Relationships of MaterialsToday’s materials can be classified as metals and alloys, as polymers or plastics, as ceramics, or as composites; composites, most of which are man-made, actually are combinations of different materials.译文：当今的材料可以分为金属和合金，聚合物或者塑料，陶瓷或复合材料；复合材料，它们大多数是人造的，实际上是不同材料组合而成。Application of these materials depend on their properties; therefore, we need to know what properties are required by the application and to be able to relate those specification to the material. 译文：这些材料的应用取决于它们的性质；因此，根据应用的场合，我们需要知道什么样的性质是必需的，我们需要能够把这些详细说明同材料联系起来。For example, a ladder must withstand a design load, the weight of a person using the ladder. However, the material property that can be measured is strength, which is affected by the load and design dimension. Strength values must therefore be applied to determined the ladder dimensions to ensure safe use. Therefore, in general, the structures of metallic materials have effects on their properties.译文：比如，一个梯子必须能经受住设计的载荷，也就是使用这个梯子的人的重量。然而，能够测量的材料的性质是强度，它为载荷和设计尺寸所影响。强度值因此被用来判定梯子的尺寸大小以保证安全使用。因此，通常说来，金属材料的结构对它们的性质有影响。In a “tensile test” a sample is gradually elongated to failure and the tensile force required to elongate the sample is measured using a load cell throughout the test. The result is a plot of tensile force versus elongation.译文：在一个张力测试实验中，样品缓慢地拉长直到失败，并且拉长样品所必需的拉力在整个测试过程中，用测压元件测量。结果是拉力同伸长度之间的一个图。The problem is that the load required to elongated the sample by a certain extent depends upon the dimension of the sample. This would be a big problem if , for example, mechanical property data were to be used to design a bridge, since it is clearly impossible to test an entire bridge. Thus what is clearly needed is to make the data from the tensile test independent of the size of the sample.译文：问题是，拉伸样品到一定程度所必需的载荷取决于样品的尺寸。比如，如果机械性质的数据被用于设计一座桥梁，既然测试整个桥梁是明显不可能的，这样，明显需要的就是从与样品尺寸无关的拉伸实验中获得数据。Thus, what is clearly needed is to make the data from the tensile test independent of the size of the sample. To achieve this end, we use “stress” and “strain”.The “true” stress( ) is defined as : ,where F=force applied to the sample at any given instant and A= current cross-sectional area of the sample.
