N09901高温合金材质物理机械性能

 N09901

牌号N09901奥氏体型时效硬化高温合金

N09901该合金在国外广泛用于航k发动机及地面燃气涡轮上在650℃以下工作的转动件和紧固件，使用寿命较长。国内也已在航k发动机上使用，是经过使用考验的成熟合金。N09901化学成分碳 C: （0.02~0.06）硅 Si: （0.40）锰 Mn: （0.50）铬 Cr: （11.0~14.0）镍 Ni: （40.0~45.0）铝Al（≤0.30）硼B（0.01~0.02）铜 Cu: (0.20)磷p（0.020）N09901合金锻造进，若工艺参数选择或操作不当时，其性能会显示明显的方向性，并可能引起缺口敏感，但只要严格工艺，就不会出现此现象。该合金膨胀系数接近铁素体型热强合金钢，使得两种材料能够连接面对热账没有特殊规定。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=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=1636353656754&bpp=7&bdt=528&idt=129&shv=r20211103&mjsv=m202111020101&ptt=9&saldr=aa&cookie=ID%3Dc309fa55da6ac3cd-223445d705cc0092%3AT%3D1632988860%3ART%3D1632988860%3AS%3DALNI_MbbnqpBTMOrORF4onces-PWAM8xaw&nras=1&correlator=988030773168&frm=23&ife=1&pv=2&ga_vid=1534799225.1636353657&ga_sid=1636353657&ga_hid=107509176&ga_fc=0&nhd=1&u_tz=480&u_his=15&u_h=768&u_w=1360&u_ah=728&u_aw=1360&u_cd=24&adx=-12245933&ady=-12245933&biw=1295&bih=597&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31063222%2C44748552&oid=2&pvsid=4054457320532454&pem=338&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&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.x3stcj44az0m&fsb=1&dtd=159" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.x3stcj44az0m" data-load-complete="true">
