声弹效应理论,在瑞利波无损表征45钢表层应力的基础上分析了45钢表层初始应力状态对应力评价结果的影响.采用声程固定不变中心频率为5MHz的双瑞利波探头对45钢表层应力进行评价,在归一化互相关函数基础上计算了应力引起的瑞利波信号间时间差.结果表明:初始应力不会影响瑞利波在45钢表层中传播速度随拉伸应力的变化规律,即随拉伸应力的增加,瑞利波在45钢表层中的传播速度基本呈线性规律增加,当应力达到一定值时,再随应力的增加,瑞利波传播速度不再呈线性规律变化；但初始应力和去应力退火状态45钢的名义瑞利波声弹性系数不同,分别为0.838和1.041,最大时间差对应的应力值也不同,去应力退火前后应力评价结果的误差约为22％.","authors":[{"authorName":"刘彬","id":"f1467ea7-732d-4193-9bf0-bc6223cf4ce1","originalAuthorName":"刘彬"},{"authorName":"董世运","id":"3c07219d-c291-4879-89ff-eedc017c7048","originalAuthorName":"董世运"},{"authorName":"徐滨士","id":"375b3431-d4d9-422d-95bb-336487861b46","originalAuthorName":"徐滨士"},{"authorName":"何鹏","id":"92c66992-97c7-42bd-be48-7a7f3305c25f","originalAuthorName":"何鹏"},{"authorName":"闫世兴","id":"760d9e56-09b9-40a3-b8a4-2ffdaf3ffb78","originalAuthorName":"闫世兴"}],"doi":"10.3969/j.issn.1001-4381.2012.05.008","fpage":"35","id":"98595b93-e3fe-4baa-840a-fbef2ad3cdce","issue":"5","journal":{"abbrevTitle":"CLGC","coverImgSrc":"journal/img/cover/CLGC.jpg","id":"9","issnPpub":"1001-4381","publisherId":"CLGC","title":"材料工程"},"keywords":[{"id":"5444860b-ea52-474d-8c1c-ffd142c87ea0","keyword":"45钢","originalKeyword":"45钢"},{"id":"8c51a4a7-fc2f-4328-a000-6f2b0aee8204","keyword":"声弹效应","originalKeyword":"声弹效应"},{"id":"7e4f1a36-7125-4a32-98ec-fd215d49ad01","keyword":"瑞利波","originalKeyword":"瑞利波"},{"id":"ec25ce8e-0bd0-4e52-b08a-ea7c58e45698","keyword":"拉伸应力","originalKeyword":"拉伸应力"}],"language":"zh","publisherId":"clgc201205008","title":"初始应力对瑞利波无损评价45钢表层应力的影响","volume":"","year":"2012"},{"abstractinfo":"基于瑞利波声弹性系数标定试验,采用一发一收瑞利波探头采集瑞利波信号,结合瑞利波信号分析探讨了热处理组织影响碳钢表层应力评价的机理.结果表明,随碳钢晶粒尺寸增大,瑞利波声弹性系数略有增大,瑞利波信号间时间差-载荷曲线的转折点载荷越接近试样弹性极限载荷,高载荷阶段瑞利波信号间时间差波动随载荷增大略有增大.分析认为,晶粒尺寸增大导致试样塑性变形能力下降、试样表面粗糙度及瑞利波探头与试样耦合质量是导致上述结果的重要原因.","authors":[{"authorName":"刘彬","id":"ee818d0b-2b2c-4d63-8015-d6c53d19c021","originalAuthorName":"刘彬"},{"authorName":"缪文炳","id":"00b42a9c-40ca-4eb8-9fc1-d309ebbfd1e4","originalAuthorName":"缪文炳"},{"authorName":"王小京","id":"08b08b63-45e4-4872-80b5-558cd52e1f7d","originalAuthorName":"王小京"},{"authorName":"乔岩欣","id":"545ebf9f-e3c1-4557-b33a-6185e32b8184","originalAuthorName":"乔岩欣"},{"authorName":"董世运","id":"c9abb8a8-bce3-411a-ac5f-00a6ad74f131","originalAuthorName":"董世运"},{"authorName":"杨敏","id":"a928ee1c-84db-4260-a175-f4b4ceffe403","originalAuthorName":"杨敏"}],"doi":"","fpage":"236","id":"355dfd1a-445b-49cb-aff1-5f724ea66671","issue":"10","journal":{"abbrevTitle":"CLRCLXB","coverImgSrc":"journal/img/cover/CLRCLXB.jpg","id":"15","issnPpub":"1009-6264","publisherId":"CLRCLXB","title":"材料热处理学报"},"keywords":[{"id":"942ab15d-4942-482d-a30c-41a783ae22c9","keyword":"瑞利波","originalKeyword":"瑞利波"},{"id":"2d630ec2-68c3-446e-9e90-3f027e5e0952","keyword":"表层应力","originalKeyword":"表层应力"},{"id":"8d2e0d47-8455-4287-925d-4022be2ea93c","keyword":"碳钢","originalKeyword":"碳钢"},{"id":"de910bb0-a6ec-44df-b247-08cde1ae9ae0","keyword":"组织","originalKeyword":"组织"},{"id":"4524e128-9e88-4038-b401-c11fd6dcd2be","keyword":"声弹效应","originalKeyword":"声弹效应"}],"language":"zh","publisherId":"jsrclxb201510038","title":"热处理组织影响瑞利波评价碳钢表层应力的研究","volume":"36","year":"2015"},{"abstractinfo":"从非线性波动方程出发,运用准平衡模型以及热弹理论,对固体样品中光声拉曼效应进行理论分析,导出了脉冲激光泵浦下光声拉曼信号的解析表达式,并总结分析了固体中光声拉曼效应的一些原理特性、实验问题和应用价值.","authors":[{"authorName":"邹文栋","id":"b7c896e6-f82b-457c-b183-9f8955219881","originalAuthorName":"邹文栋"}],"doi":"10.3969/j.issn.1007-5461.2003.02.007","fpage":"162","id":"39f955d1-167c-4408-b9f6-b474290384b4","issue":"2","journal":{"abbrevTitle":"LZDZXB","coverImgSrc":"journal/img/cover/LZDZXB.jpg","id":"53","issnPpub":"1007-5461","publisherId":"LZDZXB","title":"量子电子学报
