Description
技术领域
本发明属于激光增材制造领域;具体涉及一种硼合金化变质降低TC4钛合金激光增材制造各向异性的方法。
背景技术
激光增材制造钛合金是近年来发展起来的一项新兴技术,该技术通过高功率激光熔化同步输送的钛合金粉末,逐点逐层堆积成形零件,克服了由于钛合金本身所具有的高熔点、导热性差、高熔融态活性以及变形抗力大的特点所带来的加工难度大、复杂零件加工技术难等缺点,在航天航空和国防制造领域被越来越多的研究和应用,但是,由于激光增材制造具有即热即冷、温度梯度大的特性难以控制,造成了其钛合金成形件宏观组织为沿成形方向贯穿多个熔覆层的粗大β柱状晶,导致钛合金构件各向异性(可达到15%-70%)明显,断裂韧性和低周疲劳强度较低,从而严重制约其在国防工业和航空航天领域的应用。如何细化激光增材制造钛合金晶粒,减小其各向异性是激光增材制造钛合金研究的热点。
发明内容
本发明提供了一种通过变质剂硼与TC4合金化来降低TC4钛合金激光增材制造各向异性的新方法。使用该方法能够使得粗大的β柱状晶消失或者得到有效抑制,细化激光增材制造TC4钛合金晶粒,降低各向异性,使常规力学性能的各向异性控制在10%以内。本发明通过硼与TC4钛合金合金化的增材制造方法,可以有效地改善激光增材制造TC4宏微观组织,细化TC4晶粒,使得β柱状晶消失或者得到有效抑制,进而起到减小其各向异性的作用。有利于进一步扩大推广激光增材制造TC4钛合金在在国防工业和航空航天领域的应用。
本发明采用如下技术方案:一种硼合金化变质降低TC4增材制造各向异性的方法,硼B以合金化的方法加入到TC4钛合金中,在增材制造过程中B元素在TC4钛合金中有效地抑制粗大一次柱状晶生长,促使TC4钛合金晶粒趋于等轴与细化,有效地降低了激光增材制造TC4钛合金的各向异性,使常规力学性能的各向异性控制在10%以内,包括以下步骤:
步骤(1),制备TC4-0.05B(Ti-6Al-4V-0.05B)合金粉末,合金粉末粒度为50~150μm,将Ti-6Al-4V-0.05B合金粉末在真空环境下烘干,烘干温度为120℃,且烘干时间4~8h;合金化粉末硼元素的质量分数为0.02~0.08%;
步骤(2),使用激光增材制造装置将步骤(1)中烘干的合金化粉末在惰性气体氩气保护环境下进行激光熔覆沉积,得到成形的零件;
步骤(3),对零件在惰性气体氩气保护下进行固溶时效热处理,热处理工艺:固溶温度900~950℃,保温1~3h,空冷;时效温度500~550℃,保温4~6h,然后空冷。
所述步骤(2)中激光功率为180~240W,扫描速度为8~16mm/s,送粉量为2~3g/min。
与现有技术相比,本发明的有益效果在于:变质剂硼以合金化的方法加入到TC4钛合金中,在增材制造过程中硼元素在TC4钛合金中有效地抑制粗大一次柱状晶生长,促使TC4钛合金晶粒趋于等轴与细化,有效地降低了激光增材制造TC4钛合金的各向异性,为激光增材制造TC4钛合金开辟了一条新的途径。在激光熔覆沉积的过程中,当熔池开始凝固时,硼原子在固液界面处发生富集,从而产生成分过冷,提高形核率,细化柱状晶晶粒;另一方面,由Ti-B二元相图可知,B原子和Ti反应生成难熔相TiB,TiB相沿晶界析出,阻断α相沿原始晶界的连续生长,从而达到消除晶界的目的,最终起到提高其塑性和韧性,减小其各向异性的作用。
