并以塑性波形态进行扩展,这一现象与材料亚韧性断裂之间有相互关系.纳米晶、亚微米微晶2009铝合金试样在经受拉伸应力实验时,试样上各点的应变量在三维方向上均呈波动性变化,且随着外加载荷的增加而波动的幅度增加.塑性变形的波动的传播是在加载过程中, 试样内的剪切稳定性丧失后, 由于晶粒群转动,在试样上沿最大剪应力方向形成了吕得尔斯条带而逐步形成的.主剪切带形成了一个塑性变形的波峰, 接下去侧生条带和次生带形成波峰和波低谷区, 周而复始, 形成了塑性变形的波动的传播.应力应变峰值的形成与材料缺陷所造成应力集中有关.试样于应力集中点起始迅速开裂.宏观断裂强度仅体现了材质缺陷弥散程度的统计平均数.","authors":[{"authorName":"朱其芳","id":"5eee8328-4cec-4d7f-bd4b-b8a8e823983b","originalAuthorName":"朱其芳"},{"authorName":"孙泽明","id":"f3241d20-1db3-4701-8be9-0ebe30a88944","originalAuthorName":"孙泽明"},{"authorName":"邵贝羚","id":"b9f79192-c3e2-4660-913a-5dd32ec084f6","originalAuthorName":"邵贝羚"},{"authorName":"尤振平","id":"2c4b8bff-540d-4074-acde-fa3f0d6f0073","originalAuthorName":"尤振平"},{"authorName":"田晓峰","id":"72bb2be5-e4a7-4cff-ab71-a38b2187c373","originalAuthorName":"田晓峰"},{"authorName":"王福生","id":"849b363a-fb65-4877-8e04-f872d5c878d3","originalAuthorName":"王福生"},{"authorName":"张金波","id":"4f321586-01d0-420e-ab5e-227c3ca38e29","originalAuthorName":"张金波"}],"doi":"10.3969/j.issn.0258-7076.2007.04.010","fpage":"451","id":"ba0f44df-d82f-49fe-b1da-3eb13b8bc559","issue":"4","journal":{"abbrevTitle":"XYJS","coverImgSrc":"journal/img/cover/XYJS.jpg","id":"67","issnPpub":"0258-7076","publisherId":"XYJS","title":"稀有金属"},"keywords":[{"id":"4f3d41ef-394f-4778-b8f5-41baf9db5b67","keyword":"介观力学","originalKeyword":"介观力学"},{"id":"b85e6718-08f7-43b7-8205-fca56562f4fe","keyword":"2009铝合金","originalKeyword":"2009铝合金"},{"id":"3f9692b6-f5e0-429f-9aad-7e8184675305","keyword":"塑性","originalKeyword":"塑性"},{"id":"ad7cea2a-4a68-4409-a75a-35278a97c41f","keyword":"形变波动性","originalKeyword":"形变波动性"},{"id":"4e3b9b37-74cc-4eec-81fd-0af28184d51e","keyword":"纳米晶","originalKeyword":"纳米晶"}],"language":"zh","publisherId":"xyjs200704010","title":"纳米铝合金的断裂与塑性变形","volume":"31","year":"2007"},{"abstractinfo":"本文采用真空熔炼法制备了Fe3Al金属间化合物,借助SEM,XRD,EDX等手段研究了Fe3Al在O-S混合气氛下800-1000℃的高温腐蚀行为及其中的晶相变化、晶界扩散过程,并从热力学和动力学方面对其腐蚀机理进行了分析.结果表明:Fe3Al合金在600-900℃范围内,具有较好的抗高温腐蚀性能.当温度超过1000℃或长时间腐蚀时,腐蚀速度迅速增加.","authors":[{"authorName":"田晓峰","id":"760f9f39-e74e-4ee8-9aab-8696e8befca1","originalAuthorName":"田晓峰"},{"authorName":"王昕","id":"3bfb4422-7bf8-4c37-bf61-8611a634011a","originalAuthorName":"王昕"},{"authorName":"尹衍升","id":"90832acf-af69-41fc-aecc-ae2bfa952835","originalAuthorName":"尹衍升"},{"authorName":"韩野","id":"234808bc-1ba5-4bec-a949-6ebe718fabda","originalAuthorName":"韩野"}],"doi":"","fpage":"726","id":"6ef5e4a7-2a16-4ab3-a155-e963c525a20e","issue":"3","journal":{"abbrevTitle":"RGJTXB","coverImgSrc":"journal/img/cover/RGJTXB.jpg","id":"57","issnPpub":"1000-985X","publisherId":"RGJTXB","title":"人工晶体学报"},"keywords":[{"id":"7007b9f0-ff97-4627-ac29-5cb640ddc943","keyword":"Fe3Al金属间化合物","originalKeyword":"Fe3Al金属间化合物"},{"id":"91ab4948-c026-4bd0-9b49-35cde9a15e3a","keyword":"硫化","originalKeyword":"硫化"},{"id":"041f6ef1-8a73-4a3b-be31-6df3d1760d08","keyword":"腐蚀","originalKeyword":"腐蚀"}],"language":"zh","publisherId":"rgjtxb98200803045","title":"Fe3Al金属间化合物硫化腐蚀中晶粒变化及晶界扩散研究","volume":"37","year":"2008"},{"abstractinfo":"对粉末冶金法制备的碳化硅颗粒增强铝基复合材料进行了旋转弯曲疲劳试验研究.采用金相显微镜和扫描电镜分别观察了疲劳试验后复合材料纵向显微组织和疲劳断口.通过金相显微镜,观察了增强体颗粒在疲劳循环应力水平下可能的损伤形式.通过疲劳断口观察,分析了断面上不同区域的疲劳裂纹传播特征.结果表明,增强体的加入有效地提高了复合材料的屈服强度、弹性模量和疲劳性能,使复合材料高周疲劳极限提高到约250
