Incoloy907高温物理性能材质是什么材质

 Incoloy907镍基合金

概述：

Incoloy 907是Fe-Ni-Co基沉淀硬化型低膨胀变形高温合金，以添加铌、钛、硅和微量硼毒素进行综合强化。合金在650℃以下具有很高的强度，低的膨胀系数，良好的抗冷热疲劳性能以及几乎不变的弹性模量。居里点在400℃-450℃。居里点以下合金的膨胀系数基本不变。适于制作650℃以下使用的各类航空、航天发动机环形件和机匣，主要产品有棒材、锻件、板材和带材。化学成分：Ni;37.43Co;12.94Nb;4.77Ti;1.47Al;0.08Si;0.21Mn;0.36密度：8.28热处理制度制度A：1040℃±10℃保温1小时，空冷或快冷+800℃保温16小时以每小时55℃降温至620℃保温8小时，空冷制度B：980℃±10℃保温1小时，空冷或快冷+775℃保温12小时以每小时55℃降温至620℃保温8小时，空冷应用：合金已用于制作航空发动机高压压气机后机匣、承力环、隔热环、燃烧室封严环、蜂窝座和涡轮外环等零件，使用情况良好。LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=3%3A32%2C4%3A32%2C8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&dt=1634708996870&bpp=3&bdt=107&idt=24&shv=r20211018&mjsv=m202110130101&ptt=9&saldr=aa&cookie=ID%3Dce48580c43e890de-22e9187baecc00a0%3AT%3D1634624052%3ART%3D1634624052%3AS%3DALNI_Mb5XflzXumewSZxzeACD1WXy1WJqQ&nras=1&correlator=7864181873918&frm=23&ife=1&pv=2&ga_vid=1491967696.1634708997&ga_sid=1634708997&ga_hid=1680828302&ga_fc=0&nhd=1&u_tz=480&u_his=26&u_h=1080&u_w=1920&u_ah=1040&u_aw=1920&u_cd=24&adx=-12245933&ady=-12245933&biw=1872&bih=909&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31062526%2C44748552&oid=2&pvsid=4081794386858188&pem=747&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1664&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1040%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.hr1aoeujm92o&fsb=1&dtd=39" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.hr1aoeujm92o" data-load-complete="true">
