【《镁合金的变形机制及应用发展研究文献综述》8100字】

镁合金的变形机制及应用发展研究文献综述1镁合金的特点Mg广泛分布于自然界之中，在地壳所含化学元素中处第八位，约占2.35%。此外，Mg还在宇宙元素中居第九位。Mg属于碱土金属元素，化学性质非常活泼，基本以化合物的形式存在，所以直到1808年才成功制得金属镁。现在人们通常采用矿石提取和海水提取来获取Mg。自发现金属镁后，它独特的物理化学性质和得天独厚的优势就引起了广大科研人员的重视。镁为密排六方晶格，密度仅为1.738g/cm3。镁合金在目前实际应用的金属结构材料中密度最低，是轻质结构材料ADDINEN.CITE<EndNote><Cite><Author>杜文博</Author><Year>2020</Year><RecNum>63</RecNum><DisplayText><styleface="superscript">[2]</style></DisplayText><record><rec-number>63</rec-number><foreign-keys><keyapp="EN"db-id="rdze5zzau99z5cevfr0vv054ex0pwe9wsptr"timestamp="1622599248">63</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>杜文博</author><author>侯江涛</author><author>孟繁婧</author><author>李淑波</author></authors></contributors><auth-address>北京工业大学材料科学与工程学院;</auth-address><titles><title>碳纳米管增强镁基复合材料导热性能研究</title><secondary-title>中国材料进展</secondary-title></titles><periodical><full-title>中国材料进展</full-title></periodical><pages>12-18+30</pages><volume>39</volume><number>01</number><keywords><keyword>碳纳米管</keyword><keyword>镁合金</keyword><keyword>复合材料</keyword><keyword>导热性能</keyword><keyword>显微组织</keyword></keywords><dates><year>2020</year></dates><isbn>1674-3962</isbn><call-num>61-1473/TG</call-num><urls></urls><remote-database-provider>Cnki</remote-database-provider></record></Cite></EndNote>[2]，密度仅稍高于Mg，通常在1.75~1.85g/cm3之间，大约比铝（2.70g/cm3）轻36%，比钛（4.506g/cm3）轻的61%，比钢轻77%ADDINEN.CITE<EndNote><Cite><Author>柳杨璐</Author><Year>2018</Year><RecNum>2</RecNum><DisplayText><styleface="superscript">[3]</style></DisplayText><record><rec-number>2</rec-number><foreign-keys><keyapp="EN"db-id="rdze5zzau99z5cevfr0vv054ex0pwe9wsptr"timestamp="1621310840">2</key></foreign-keys><ref-typename="Thesis">32</ref-type><contributors><authors><author>柳杨璐</author></authors><tertiary-authors><author>潘复生,</author></tertiary-authors></contributors><titles><title>Mg-Al和Mg-Y合金的第一性原理计算及实验研究</title></titles><keywords><keyword>镁合金</keyword><keyword>合金元素</keyword><keyword>临界剪切应力</keyword><keyword>力学性能</keyword><keyword>变形机制</keyword></keywords><dates><year>2018</year></dates><publisher>重庆大学</publisher><work-type>硕士</work-type><urls></urls><remote-database-provider>Cnki</remote-database-provider></record></Cite></EndNote>[3]。这是镁合金最突出的优点。假如我们能够通过采用镁合金来使车辆重量减少100公斤，那么车辆行驶100km我们可以减少0.38L的燃料使用量和8.7g的CO2排放量ADDINEN.CITE<EndNote><Cite><Author>Zeng</Author><Year>2017</Year><RecNum>8</RecNum><DisplayText><styleface="superscript">[4]</style></DisplayText><record><rec-number>8</rec-number><foreign-keys><keyapp="EN"db-id="rdze5zzau99z5cevfr0vv054ex0pwe9wsptr"timestamp="1621402644">8</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>ZhuoranZeng</author><author>Jian-FengNie</author><author>Shi-WeiXu</author><author>ChrisH.J.Davies</author><author>NickBirbilis</author></authors></contributors><auth-address>0000000419367857,grid.1002.3,DepartmentofMaterialsScienceandEngineering,MonashUniversity,3800,Melbourne,Vic,Australia;;grid.484636.b,AutomotiveSteelResearchInstitute,ResearchInstitute(R&DCentre),BaoshanIron&SteelCo.,Ltd,201900,Shanghai,China;;0000000419367857,grid.1002.3,DepartmentofMechanicalandAerospaceEngineering,MonashUniversity,3800,Melbourne,Vic,Australia</auth-address><titles><title>Super-formablepuremagnesiumatroomtemperature</title><secondary-title>NatureCommunications</secondary-title></titles><periodical><full-title>NatureCommunications</full-title></periodical><volume>8</volume><number>1</number><dates><year>2017</year></dates><urls></urls><remote-database-provider>Cnki</remote-database-provider></record></Cite></EndNote>[4]。因为环境和能源问题越来越严峻，不管是汽车、能源、航空还是电子设备等各个领域都在追求轻量化。毫无疑问，镁合金将会成为这些制造行业的首选材料。镁合金的弹性模量为44.8GPa，泊松比为0.35，这意味着当施加同样的载荷时，镁合金能够消耗更多的变形功，优良的减震吸振性能也是市场选择它的理由ADDINEN.CITE<EndNote><Cite><Author>樊振中</Author><Year>2020</Year><RecNum>5</RecNum><DisplayText><styleface="superscript">[5]</style></DisplayText><record><rec-number>5</rec-number><foreign-keys><keyapp="EN"db-id="rdze5zzau99z5cevfr0vv054ex0pwe9wsptr"timestamp="1621320153">5</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>樊振中</author><author>陈军洲</author><author>陆政</author><author>熊艳才</author></authors></contributors><auth-address>中国航发北京航空材料研究院;北京市先进铝合金材料及应用工程技术研究中心;</auth-address><titles><title>镁合金的研究现状与发展趋势</title><secondary-title>铸造</secondary-title></titles><periodical><full-title>铸造</full-title></periodical><pages>1016-1029</pages><volume>69</volume><number>10</number><keywords><keyword>镁合金</keyword><keyword>研究现状</keyword><keyword>发展趋势</keyword><keyword>表面防护</keyword><keyword>微观组织</keyword><keyword>力学性能</keyword></keywords><dates><year>2020</year></dates><isbn>1001-4977</isbn><call-num>21-1188/TG</call-num><urls></urls><remote-database-provider>Cnki</remote-database-provider></record></Cite></EndNote>[5]。除此之外，镁合金的比强度和比刚度也高于这些材料。这意味着，如果我们在工程上采用镁合金，不仅能够不减少零部件强度，还能够极大地减轻工件质量。近年来，镁合金的相关产业不断发展，从科学研究到投入使用，成本不断降低，性能不断改善，其工业化应用已经成为材料领域的研究热点。镁合金的低密度是与生俱来的优势。但是不可忽视的是处于室温下时，工业纯镁强度低、塑性差，而且受温度变化影响很大，无法直接作为结构材料而使用。这也正是因为镁自身的3s2自由价电子结构，这种结构导致镁无法构成共价键，因此具有最低的平均价电子结合能和非常弱的原子结合力ADDINEN.CITE<EndNote><Cite><Author>曾小勤</Author><Year>2019</Year><RecNum>6</RecNum><DisplayText><styleface="superscript">[6]</style></DisplayText><record><rec-number>6</rec-number><foreign-keys><keyapp="EN"db-id="rdze5zzau99z5cevfr0vv054ex0pwe9wsptr"timestamp="1621322509">6</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>曾小勤</author><author>朱庆春</author><author>李扬欣</author><author>丁文江</author></authors></contributors><auth-address>上海交通大学材料科学与工程学院轻合金精密成型国家工程研究中心;上海交通大学材料科学与工程学院金属基复合材料国家重点实验室;</auth-address><titles><title>镁合金中的第二相颗粒强化</title><secondary-title>中国材料进展</secondary-title></titles><periodical><full-title>中国材料进展</full-title></periodical><pages>193-204+250</pages><volume>38</volume><number>03</number><keywords><keyword>镁合金</keyword><keyword>第二相</keyword><keyword>时效强化</keyword><keyword>长周期堆垛有序结构相</keyword><keyword>镁基增强体</keyword></keywords><dates><year>2019</year></dates><isbn>1674-3962</isbn><call-num>61-1473/TG</call-num><urls></urls><remote-database-provider>Cnki</remote-database-provider></record></Cite></EndNote>[6]。这种有限的强度和塑性很大程度上限制了镁合金的应用潜力。2镁合金的分类镁合金一般有三种分类方式，分别为：合金化学成分、成形工艺ADDINEN.CITE<EndNote><Cite><Author>Kojima</Author><Year>2001</Year><RecNum>62</RecNum><DisplayText><styleface="superscript">[7]</style></DisplayText><record><rec-number>62</rec-number><foreign-keys><keyapp="EN"db-id="rdze5zzau99z5cevfr0vv054ex0pwe9wsptr"timestamp="1622564735">62</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>YoKojima</author></authors></contributors><auth-address>DepartmentofMechanicalEngineering,NagaokaUniversityofTechnology</auth-address><titles><title>ProjectofPlatformScienceandTechnologyforAdvancedMagnesiumAlloys</title><secondary-title>MATERIALSTRANSACTIONS</secondary-title></titles><periodical><full-title>MATERIALSTRANSACTIONS</full-title></periodical><volume>42</volume><number>7</number><keywords><keyword>Advancedmagnesiumalloys</keyword><keyword>Platformscience</keyword><keyword>Platformtechnology</keyword><keyword>Microstructurecontrol</keyword><keyword>Surfacemodification</keyword><keyword>Eco-material</keyword><keyword>Environmentalburden</keyword><keyword>Structuralspacematerial</keyword><keyword>Newfunctionality</keyword><keyword>Biomaterial</keyword></keywords><dates><year>2001</year></dates><isbn>1345-9678</isbn><urls></urls><remote-database-provider>Cnki</remote-database-provider></record></Cite></EndNote>[7]和应用工况与服役载荷。2.1合金化学成分按照合金化学成分不同主要可以分为四个系列，即AZ（Mg-Al-Zn）系列、AM（Mg-Al-Mn）系列、AS（Mg-Al-Si）系列和AE（Mg-Al-RE）ADDINEN.CITE<EndNote><Cite><Author>王宣</Author><Year>2019</Year><RecNum>13</RecNum><DisplayText><styleface="superscript">[8]</style></DisplayText><record><rec-number>13</rec-number><foreign-keys><keyapp="EN"db-id="rdze5zzau99z5cevfr0vv054ex0pwe9wsptr"timestamp="1621439935">13</key></foreign-keys><ref-typename="JournalArticle">17</ref-type><contributors><authors><author>王宣</author><author>李秀兰</author><author>周立玉</author><author>曾洪亮</author></authors><translated-authors><author>WangXuan</author><author>L.I.Xiu-lan</author><author>ZhouLi-yu</author><author>ZengHong-liang</author></translated-authors></contributors><auth-address>四川轻化工大学</auth-address><titles><title>高强镁合金的制备研究进展
