Description
技术领域
本发明属于金属材料领域,尤其是一种镍铬电热合金。
背景技术
电热合金是一种能使电能有效地转换为热能,可用作发热元件的功能性材料。按化学成分分为Ni-Cr-(Fe)系合金和Fe-Cr-Al系合金两大类。
Ni-Cr-(Fe)系合金是以镍作为基体,加入不同量的铬(和铁)组成的合金系列。与Fe-Cr-Al系合金相比,Ni-Cr-(Fe)系合金能形成稳定连续的γ固溶体,单一的奥氏体组织和极窄的凝固温度区间,确保了材料具有高度均匀和稳定的力学和物理性能,是电热合金最理想的组织结构。
目前镍铬合金主要有两个牌号:Cr20Ni80和Cr30Ni70,其中Cr20Ni80应用最为广泛,其电阻率1.05~1.10uΩ·m、熔点≥1400℃、使用温度高达900℃,且具有极低的热膨胀系数、良好的抗高温氧化性能以及优异的冷热加工性能,已成为各主要工业国家重要的电热合金材料。
然而,各国的Cr20Ni80合金性能质量差异比较大。日本、美国等工业发达国家的合金丝寿命已达8000h,俄罗斯也超过6000h,而有些国家的Cr20Ni80合金丝寿命仅为2000h左右,究其原因,最主要是合金成分设计和加工工艺方面的差异。
为优化Cr20Ni80合金的成分体系和加工工艺,科研工作者做了大量的研究工作。
公开号CN112375930A,公开了一种高电阻镍铬电热合金及其生产工艺,其最主要特点是设计加入Ca、Y、La、Ce四种微量元素提高凝固过程形核率,细化晶粒、提高合金性能,但其成分体系较复杂,公开的熔炼工艺难以保证Ca、Y等易挥发、易氧化元素的精确控制,并不可取。
公开号CN110819850A,公开了一种镍铬电热合金及其制备方法,该合金最主要特点是设计加入锆、钒、钼、稀土等元素,且采用粉末冶金工艺,得到电阻率大于1.3Ωmm2/m、工作温度达1350℃的合金,是一个比较新颖的技术方案,但其工艺较复杂,成分设计有缺陷(如含有S、N等有害元素),也不可取。
此外,公开号CN101899593A、CN108901088A等也公开了不同成分的镍铬合金,但要么成分体系复杂、要么材料性能较差,均不可取。
因此,设计成分体系更完善、材料物理性能更优异的Cr20Ni80合金,是电热材料发展亟待解决的难题之一。
发明内容
本发明的目的是通过合理的成分设计,解决现有Cr20Ni80合金力学、电热性能较差等问题。
为解决以上技术问题,本发明的技术方案是:一种镍铬合金,所述合金成分及其质量百分含量为:C≤0.15%、Si 0.6~1.8%、Mn≤0.6%、P≤0.01%、S≤0.01%、Cr 19~21%、Al≤0.3%、Fe≤1.2%、Ti 0.35~0.45%、Re 0.05~0.10%、B 0.005~0.010%、余量为Ni和不可避免杂质。
优选的,镍铬合金成分及其质量百分含量为:C 0.05~0.10%、Si 0.8~1.2%、Mn0.2~0.4%、P≤0.008%、S≤0.006%、Cr 19.5~20.5%、Al 0.15~0.20%、Fe 0.5~1.0%、Ti 0.38~0.42%、Re 0.06~0.08%、B 0.007~0.009%、余量为Ni和不可避免杂质。
进一步的,所述镍铬合金,900℃抗拉强度为140~158MPa,950℃冲击韧性为147~180J/cm2,900℃、1000h伸长1%的蠕变强度为13~16MPa,20℃延伸率≥30%,线性膨胀系数a×10-6/℃(20~1000℃)为16.48~16.71,20℃电阻率为1.18~1.20uΩ/m。
本发明各成分在合金中作用如下:
(1)合金中添加了0.05~0.1%的Re,由于Re为5d区元素,而Ni为3d区元素,Re原子半径比Ni大10%,与Ni错配度很大,加入后可有效阻碍位错运动,从而增加Ni的强度,特别是蠕变强度;同时,由于Re有20%的原子处于晶界位置,且会形成约1nm的短程有序的原子团,其较大的有序区域可抑制Cr23C6、Cr7C3等TCP相在晶界的析出,改善合金的冷热加工性能。
(2)合金中添加了0.005~0.010%的B,合金中的B以M3B2形式存在并在晶界富集,增加晶界结合力,M3B2为颗粒状或块状形式分布,阻止晶界滑移和空洞的形成,可显著提高合金的力学性能;此外,适量的B也可以净化晶界,减少有害元素在晶界的析出。
(3)合金中添加了0.35~0.45%的Ti,Ti可与C形成高熔点的TiC,在凝固时首先析出,作为非均质形核质点,增加形核率,起到细化晶粒的作用。此外,Ti、Al与Ni可形成有序相Ni3(Al,Ti),与基体FCC相共格,但Ni3(Al,Ti)存在反向畴界面缺陷,位错在由FCC相进入Ni3(Al,Ti)需克服APB能,这就需要成对位错才能穿越Ni3(Al,Ti),完全限制了刃型位错的运动,同时使得螺型位错被{111}面上交叉滑移锁定,阻碍了位错运动,而这种阻碍在高温下更为明显,这将能提高材料的高温强度,减少线膨胀系数。
(4)合金中添加了适量的Al,除形成Ni3(Al,Ti)外,还可改善合金的抗氧化性能。加入Al以后,氧化膜主相为Cr2O3相,次相为α-Al2O3相,α-Al2O3相可增加Cr2O3相与基体金属间的附着力,游离的Al还可在高温下消耗氧,抑制氧的渗透速率,提高了合金的抗氧化性能。
采用上述技术方案所产生的有益效果在于:
本发明合金的力学、物理性能均优于现有的Cr20Ni80合金,成分设计上,也没有添加现有工艺“真空感应熔炼+电渣重熔”过程难以精确控制的Zr、La、Ce等易氧化、易挥发元素,工艺再现性好,可操作性强,易于推广。
