金相组织结构
播报编辑合金标准热处理状态的组织由γ基体、Ti(C、N)、Nb(C、N)、M23C6碳化物和γ'[Ni3(Al、Ti、Nb)]相组成，γ'含量大约为14.5%，是合金的主要强化相。
工艺性能与要求
播报编辑1、合金的锻造温度在1220～950℃之间均易成形。该合金在剧烈成形工序后就进行固溶处理。2、该合金的晶粒度平均尺寸与锻件的变形程度、终锻温度密切相关。3、合金具有较好的焊接性能，可进行各种焊接。焊接后进行时效处理可获得近似完全热处理状态的强度。4、零件热处理就在无硫的中性或还原性气氛中进行，以免发生硫化。新手上路成长任务编辑入门编辑规则本人编辑我有疑问内容质疑在线客服官方贴吧意见反馈投诉建议举报不良信息未通过词条申诉投诉侵权信息封禁查询与解封©2025 Baidu 使用百度前必读 | 百科协议 | 隐私政策 | 百度百科合作平台 | 京ICP证030173号 京公网安备11000002000001号window.PAGE_DATA= {"lemmaId":9505243,"lemmaTitle":"","lemmaDesc":"镍基高温合金","lemmaType":0,"uid":109609351,"uname":"上海镍晟","createTime":1267779474,"updateTime":1704715270,"isDefault":0,"isDeleted":0,"rank":1,"extData":{"isBaikeV6":1,"isFrontV6":1,"isSapp":0,"isWaitForPersonal":false,"kpdClassify":[{"id":337502,"name":"工业产品"}],"lemmaId":3322030,"lemma_id":3322030,"naturalAdConf":{"industrial":true},"newEditor":1,"pass_count":12,"subLemmaId":3322030,"updateTime":1704715270,"wapEdit":0},"extFlag":0,"versionId":559904406,"versionUid":123714731,"versionUname":"月落君独酔","versionCreateTime":1704244978,"catalog":[{"level":1,"title":"基本信息","index":"1","uuid":"gnfgzvfqpu","height":28},{"level":2,"title":"1.1、材料牌号","index":"1-1","uuid":"gnfgzvjmi4","height":21},{"level":2,"title":"1.2、相近牌号","index":"1-2","uuid":"gnfgzvjmlh","height":21},{"level":2,"title":"1.3、材料的技术标准","index":"1-3","uuid":"gnfgzvjmnb","height":37},{"level":2,"title":"1.4、化学成分","index":"1-4","uuid":"gnfgzuyoua","height":21},{"level":2,"title":"1.5、热处理制度","index":"1-5","uuid":"gnfgzuytzk","height":21},{"level":2,"title":"1.6、品种规格与供应状态","index":"1-6","uuid":"gnfgzuyua8","height":37},{"level":2,"title":"1.7、熔炼与铸造工艺","index":"1-7","uuid":"gnfgzuyujp","height":37},{"level":2,"title":"1.8、应用概况与特殊要求","index":"1-8","uuid":"gnfgzuyuog","height":37},{"level":1,"title":"物理及化学性能","index":"2","uuid":"gnfgzuyusu","height":28},{"level":2,"title":"2.1、热性能","index":"2-1","uuid":"gnfgzuyuw0","height":21},{"level":2,"title":"2.2、密度","index":"2-2","uuid":"gnfgzuyyyn","height":21},{"level":2,"title":"2.3、电性能","index":"2-3","uuid":"gnfgzuyz3f","height":21},{"level":1,"title":"金相组织结构","index":"3","uuid":"gnfgzvfwrs","height":28},{"level":1,"title":"工艺性能与要求","index":"4","uuid":"gnfgzvfwv1","height":28}],"abstract":[],"abstractAlbum":{"content":[{"albumId":1,"src":"2934349b033b5bb51be9698e3ed3d539b600bc80","width":710,"height":532,"uuid":"pc0bc80"}],"desc":"概述图册","total":1,"coverPic":{"albumId":1,"url":"https://bkimg.cdn.bcebos.com/pic/2934349b033b5bb51be9698e3ed3d539b600bc80?x-bce-process=image/resize,m_lfit,w_536,limit_1/quality,Q_70","src":"2934349b033b5bb51be9698e3ed3d539b600bc80","origSrc":"2934349b033b5bb51be9698e3ed3d539b600bc80","width":710,"height":532,"uuid":"pc0bc80"}},"modules":{"discussion":{"showHelpEdit":1},"globalConfig":{"data":{"serviceAdLemmaCategory":[337597,337474]}},"paper":{"switch":false},"pinzhuan":{}},"albums":[{"albumId":1,"desc":"概述图册","total":1,"coverPic":{"albumId":1,"src":"2934349b033b5bb51be9698e3ed3d539b600bc80","url":"https://bkimg.cdn.bcebos.com/pic/2934349b033b5bb51be9698e3ed3d539b600bc80?x-bce-process=image/resize,m_lfit,w_536,limit_1/quality,Q_70","width":710,"height":532,"desc":"概述图册","uuid":"pc0bc80"},"content":[{"albumId":1,"src":"2934349b033b5bb51be9698e3ed3d539b600bc80","url":"","width":710,"height":532,"uuid":"pc0bc80"}]}],"card":{"type":243,"left":[{"key":"name","title":"中文名","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":""}]}]},{"key":"foreignName","title":"外文名","isArray":true,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":""}]}]}],"right":[{"key":"customDefault","title":"材料牌号","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":""}]}]},{"key":"customDefault","title":"相近牌号","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"Inconel X-750"}]}]},{"key":"customDefault","title":"材料技术标准","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"合金毛细管材"}]}]}]},"lemmaCnt":1,"tips":{"isPolyseme":0},"encodeLemmaId":"0d89feb36de169fb564ef82f","versionUk":"Pg9dnfGkQoDuIKhSKEIs0Q","description":" 合金主要是以γ\"Ni3(Al、Ti、Nb)相进行时效强化的镍基高温合金，在980℃以下具有良好的耐腐蚀和抗氧化性能，800℃以下具有较高的强度，54..."}window.__abbaidu_2020_subidgetf||(window.__abbaidu_2020_subidgetf=function(){return"01000000"}) GH145合金具有以下特性：GH145在980℃以下具有良好的耐腐蚀和抗氧化性能，800℃以下具有较高的强度，540℃以下具有较好的耐松弛性能，同时还具有良好的成形性能和焊接性能，在低温环境中有优异的机械性能.
