Incoloy 907 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。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。由于合金不含铬、铝元素。高温抗氧化能力较差。在700℃以上长时间使用时,应当采取适当的防护涂层。合金表面可经过喷丸处理,喷丸后可掉高旋转弯曲疲劳15%左右。元素 C Cr Co Ni Al Ti Fe Nb B S P Si Mn Cu最小 12.0 35.0 1.3 Bal 4.3 0.07 最大 0.06 1.0 16.0 40.0 0.2 1.8 5.2 0.012 0.015 0.015 0.35 1.0 0.5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,空冷密度:8.28LED">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=1%3A1024%2C2%3A1024%2C3%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=32.0.0*&pra=5&wgl=1&dt=1636773316080&bpp=9&bdt=226&idt=141&shv=r20211109&mjsv=m202111080101&ptt=9&saldr=aa&cookie=ID%3D9f5c25f4e85d4145-22be6247a5ce0023%3AT%3D1636773246%3ART%3D1636773246%3AS%3DALNI_MZNfhBz1bjFd732cVb37zKuUs6eLQ&nras=1&correlator=2643533054425&frm=23&ife=1&pv=1&ga_vid=297689620.1636773316&ga_sid=1636773316&ga_hid=1119647080&ga_fc=0&nhd=1&u_tz=480&u_his=7&u_h=768&u_w=1360&u_ah=728&u_aw=1360&u_cd=24&DMC=2&adx=-12245933&ady=-12245933&biw=1295&bih=597&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&oid=2&pvsid=4241398464927284&pem=99&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1360%2C0%2C1360%2C728%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.9udq29xnnl3r&fsb=1&dtd=156" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.9udq29xnnl3r" data-load-complete="true"> |
