小冲杆试验法对材料力学性能的摘要资料.docx

PAGE \* MERGEFORMATVII 小冲杆试验法对材料力学性能的研究摘要 小冲杆试验技术是采用微小试样评定材料力学性能的一种新的测试方法。小冲杆试验技术不仅在抗拉强度、屈服强度和高温蠕变等领域取得了较大的发展，还促进了相关学科的发展。试验所选用的小冲杆试验机在核工业、石油化工以及航空航天方面的应用前景是非常广阔的，适用于不能取出传统试样或取样不是非常经济的场合，主要用来测定材料的力学性能，同时利用Origin制图软件对试验得到的数据进行曲线拟合进而求出蠕变参数。 关键词：小冲杆试验；力学性能；曲线拟合；蠕变参数 Abstract Small punch test technique is to use a material assessment of the mechanical properties of small samples of new test methods. Small punch test technology not only in tensile strength, yield strength and high temperature creep and other fields has made great progress, but also promoted the development of related disciplines. Test the selected punch test machine in the nuclear industry, petroleum chemical industry and potential applications in aerospace area is very broad for traditional sample can not be removed or sampling is not very economical occasions, mainly used for measuring mechanical properties of materials , while using Origin graphics software for test data obtained by curve fitting and then find the creep parameters. Keywords: small punch test; mechanical properties; curve fitting; creep parameters.  目录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc447055347 上海师范大学本科毕业论文诚信声明（设计）  PAGEREF _Toc447055347 \h I  HYPERLINK \l _Toc447055348 上海师范大学本科毕业论文（设计）选题登记表  PAGEREF _Toc447055348 \h II  HYPERLINK \l _Toc447055349 上海师范大学毕业论文（设计）指导记录表  PAGEREF _Toc447055349 \h IV  HYPERLINK \l _Toc447055350 摘要  PAGEREF _Toc447055350 \h V  HYPERLINK \l _Toc447055351 1绪论  PAGEREF _Toc447055351 \h 1  HYPERLINK \l _Toc447055352 2小冲杆试验法原理及存在的问题  PAGEREF _Toc447055352 \h 2  HYPERLINK \l _Toc447055353 2.1 试验材料的选取  PAGEREF _Toc447055353 \h 2  HYPERLINK \l _Toc447055354 2.2 小冲杆试验法原理  PAGEREF _Toc447055354 \h 3  HYPERLINK \l _Toc447055355 2.3 小冲杆试验法实验装置  PAGEREF _Toc447055355 \h 3  HYPERLINK \l _Toc447055356 2.4 试验法存在的问题  PAGEREF _Toc447055356 \h 7  HYPERLINK \l _Toc447055357 2.5 试验法研究的目的  PAGEREF _Toc447055357 \h 7  HYPERLINK \l _Toc447055358
