The results show that the addition of carbon prolongs the incubation period of deformation enhanced ferrite transformation (DEFT). Therefore, the higher strain is needed to accomplish the transformation, and the overall transformation kinetics becomes slower in the higher carbon content steels. During deformation, the ferrite grains nucleate repeatedly and rapidly in the form necklace-like at the front of the phase boundaries between the ferrite and austenite until the transformation is completed. Based on DEFT, the microstructures with ultra-fine equiaxed ferrite grains of 2-4μm can be obtained in steels. The more pronounced ferrite refinement is achieved as carbon content increased.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/zk/search.aspx?key=K%3d%5b%e4%bd%8e%e7%a2%b3%e9%92%a2%5d' title='低碳钢'>低碳钢</a> <a href='/subject/article.aspx?id=622930' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e5%bd%a2%e5%8f%98%e5%bc%ba%e5%8c%96%e7%9b%b8%e5%8f%98%5d' title='形变强化相变'>形变强化相变</a> <a href='/zk/search.aspx?key=K%3d%5b%e6%99%b6%e7%b2%92%e7%bb%86%e5%8c%96%5d' title='晶粒细化'>晶粒细化</a> <a href='/subject/article.aspx?id=2513766' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e7%a2%b3%e5%90%ab%e9%87%8f%5d' title='碳含量'>碳含量</a> <a href='/subject/article.aspx?id=3460925' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e8%bd%ac%e5%8f%98%e5%8a%a8%e5%8a%9b%e5%ad%a6%5d' title='转变动力学'>转变动力学</a> </p><p class='class'><strong>分 类 号：</strong><a href='/zk/search.aspx?key=C%3dTG111.2' title='TG111.2'>TG111.2</a>[<a href = '/domain/article.aspx?id=148' >金属学及工艺—物理冶金</a>] <a href='/zk/search.aspx?key=C%3dTG142.31' title='TG142.31'>TG142.31</a>[<a href = '/domain/article.aspx?id=147' >金属学及工艺—金属学</a>] </p> </div> <div id="content_wzxg" name="wzxg" class="article-graph"> <object width="695" height="250" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="FlashID"> <param value="../flash/relation.swf" name="movie"> <param value="high" name="quality"> <param value="opaque" name="wmode"> <param value="6.0.65.0" name="swfversion"> <param value="dataUrl=/ajax/articlerelativegraph.ashx?id=10851533" name="flashVars"> <embed width="695" height="250" src="../flash/relation.swf" type="application/x-shockwave-flash" quality="high" wmode="opaque" flashvars="dataUrl=/ajax/articlerelativegraph.ashx?id=10851533"> </embed> </object> </div> <div class="article-relate-list"> <div class="relate-list"> <p id="ckwx_br"> </p> <h2 name="ckwx" id="ckwx">参考文献：</h2> <div id="listckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jckwx_br"> </p> <h2 name="2jckwx" id="2jckwx">二级参考文献：</h2> <div id="list2jckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="ohwx_br"> </p> <h2 name="ohwx" id="ohwx">耦合文献：</h2> <div id="listohwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="yzwx_br"> </p> <h2 name="yzwx" id="yzwx">引证文献：</h2> <div id="listyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jyzwx_br"> </p> <h2 name="2jyzwx" id="2jyzwx">二级引证文献：</h2> <div id="list2jyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="tbywx_br"> </p> <h2 name="tbywx" id="tbywx">同被引文献：</h2> <div id="listtbywx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="xgqklw_br"> </p> <h2 name="xgqklw" id="xgqklw">相关期刊文献：</h2> <div id="listxgqklw"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> </div> </div> <div class="article-about"> <div class="about-box"> <h5 class="name">相关的主题<tt><a class="hide" href="#"></a></tt></h5> <div class="about-list"> </div> </div> <div class="about-box"> <h5 class="name">相关的作者对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> <div class="about-box"> <h5 class="name">相关的机构对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> </div> </div> </div> <script type="text/javascript" src="/scripts/articlerelation.min.js"></script> <script type="text/javascript" src="/scripts/articlerightrelation.min.js"></script> <script type="text/javascript" src="/scripts/articledown.min.js"></script> <div class="layer-box download" id="downloadlayer" style="display: none"> <div class="close"> <a onclick="closedown()" href="javascript:void(0)"> <img src="/images/layer-close.png" width="21" height="21" alt="" /> </a> </div> <h5 class="layer-title">下载全文</h5> <div id="downloadinfo"></div> </div> <div class="layer-box download" id="downloadlayer2" style="display:none;min-height:100px;width:500px;"> <p> <img src="/images/loading2.gif" width="64" height="64"> <span style="font-size:20px;vertical-align:middle;padding-bottom:50px;">正在链接到云南高校图书馆文献保障联盟下载...</span> </p> </div> <script id="bdshare_js" data="type=tools&uid=0" type="text/javascript"></script> <script type="text/javascript"> $(function () { var rd = GetQueryString("rd");
