nm),在这个晶粒尺寸范围之外,去孪晶起主导作用使原有的生长孪晶或变形孪晶消失;(3)位错密度是影响位错与孪晶反应的新的影响因素.当发生孪晶的晶粒内位错密度低时,位错可完全穿过孪晶界,部分穿过孪晶界,或被孪晶界吸收;发生孪晶的晶粒内位错密度高时,大量位错缠绕并堆积在孪晶界附近,形成应力集中,破坏孪晶界原有的共格性.为释放局部应力,将从孪晶界的另一侧发射不全位错形成层错和二次孪晶;(4)在塑性变形导致的晶粒长大过程中,原先偏聚于消失了的晶界上的C和S沿残留晶界扩散并继续偏聚于晶界上.结构与力学性能关系结果表明:随着应变量的增加,应变强化、应变软化交替出现.位错密度对硬度的演变起主导作用,其它结构演变(如孪晶密度的变化和晶粒尺寸变化)对硬度的演变起次要作用.","authors":[{"authorName":"倪颂","id":"58c22919-bcc5-4be1-af61-768e16ace6b4","originalAuthorName":"倪颂"},{"authorName":"","id":"fcd75ec5-0add-4887-9009-be351acd4ca3","originalAuthorName":"廖晓舟"},{"authorName":"朱运田","id":"2c19e91b-bf54-4b3c-ae6d-4ee183ff2b09","originalAuthorName":"朱运田"}],"doi":"10.3724/SP.J.1037.2013.00616","fpage":"156","id":"80700b99-2c78-4023-bbc4-a87b9737e846","issue":"2","journal":{"abbrevTitle":"JSXB","coverImgSrc":"journal/img/cover/JSXB.jpg","id":"48","issnPpub":"0412-1961","publisherId":"JSXB","title":"金属学报"},"keywords":[{"id":"ad149ee6-5ddf-4f58-aace-514da0106aac","keyword":"剧烈塑性变形","originalKeyword":"剧烈塑性变形"},{"id":"ef679691-1763-4985-a581-3863d60edd16","keyword":"纳米材料","originalKeyword":"纳米材料"},{"id":"bac2b5da-a92d-4876-90b2-16696a58b869","keyword":"位错","originalKeyword":"位错"},{"id":"54910335-578f-4d41-9770-37f7d16c24f6","keyword":"孪晶","originalKeyword":"孪晶"},{"id":"2fdce715-3f04-49da-95dd-d48e71f85d45","keyword":"应变强化","originalKeyword":"应变强化"},{"id":"6d13cd71-80cd-4823-a9d2-feae6ae442c0","keyword":"应变软化","originalKeyword":"应变软化"}],"language":"zh","publisherId":"jsxb201402006","title":"剧烈塑性变形对块体纳米金属材料结构和力学性能的影响","volume":"50","year":"2014"},{"abstractinfo":"现代工业的发展需要生产出更高纯度的钼粉,为此在钼粉还原生产中采用纯钼板制成的料以避免钼粉受到污染;然而纯钼料常常因破裂失效而增加了生产成本。从料的使用工况入手,分析环境气氛、热应力对料的影响;对不同服役时间的料取样,测试料材料的硬度及抗弯强度,并观察相应的金相组织。结果表明,料失效的主要原因是料服役温度超过了纯钼的再结晶温度,长期的高温使用使制作料的轧制钼板的致密纤维组织转变为粗大的等轴晶组织,材料出现脆化(再结晶脆性)。基于料的失效分析,对钼粉生产中料材料的选择提出建议。","authors":[{"authorName":"周航","id":"48f41bc3-6612-4336-8ffd-cb7dc8a61eec","originalAuthorName":"周航"},{"authorName":"张云鹏","id":"b8b059d0-31b2-4e24-bcfe-510481e0a32e","originalAuthorName":"张云鹏"},{"authorName":"王华","id":"e2383c93-8ebc-46b0-8be6-77baf9ea4826","originalAuthorName":"王华"},{"authorName":"杨志怀","id":"ffa37230-17b7-4dcc-81a1-c011076b928c","originalAuthorName":"杨志怀"}],"doi":"","fpage":"104","id":"edc5fc56-cc48-4a91-b725-de7c88ad9fab","issue":"6","journal":{"abbrevTitle":"BQCLKXYGC","coverImgSrc":"journal/img/cover/BQCLKXYGC.jpg","id":"4","issnPpub":"1004-244X","publisherId":"BQCLKXYGC","title":"兵器材料科学与工程
