Description

钼-硅-硼合金和其制造方法以及构件
技术领域
本发明涉及一种特殊的钼-硅-硼合金，一种制造方法和一种构件。
背景技术
Mo-(x)Si-(y)B合金被视为制造用于燃气轮机的热气构件的潜在可行性，其超越了传统的镍基超级合金的使用窗口。所述合金提供高达1973K的使用窗口，以高达2073K的热气温度进行覆层。因此，与迄今使用的合金相比，能够以高达300K来扩展使用范围，结合有效率的相应提高。
所述合金的加工一方面能够通过粉末冶金途径进行，另一方面借助区域熔化进行。尤其由于所产生的温度梯度，区域熔化引起纤维-基体结构的构成，所述纤维-基体结构由于其在高于1273K的温度下突出的蠕变特性而令人印象深刻。
然而，这两种方法仅允许形成简单的样本，使得所述合金的潜力目前不能被充分利用。
发明内容
因此，本发明的目的是解决上述问题。
所述目的通过根据权利要求1的合金，根据权利要求2的方法和根据权利要求4的构件实现。
提出一种借助增材制造法(AM)，如选择性激光熔化(SLM)来加工的新型Mo-Si-B合金。此外，借助能量射束，如激光射束与粉末床中的散热条件相结合所进行的加工，允许构成热传导梯度，所述热传导梯度又有利于可选地期望形成纤维-基体结构，在所述纤维-基体结构中各个相作为Moss/Mo5SiB2/Mo3Si结构存在。
在此，(0.5原子％至2原子％)锆(Zr)的可选的合金化引起合金或构件的断裂韧性的有利的提高。
此外，与粉末冶金工艺对比，AM工艺提供了使氧气尽可能远离工件的优点。这对材料特性产生积极影响。
具体实施方式
有利的是用于借助于AM工艺进行的制造工艺的工艺数据：
合金：Mo-(x)Si-(y)B，
其中x＝3原子％至19原子％并且y＝1原子％至13原子％，
优选x＝13原子％至18原子％并且y＝8原子％至12原子％，
可选地添加锆(Zr)z＝0.5原子％至2原子％，
优选z＝1原子％，
粒度：10μm至60μm，气体雾化或研磨，
作为可行的工艺窗口：
扫描速度：400mm/s至2000mm/s，
优选1000mm/s至1500mm/s，
激光功率：80W至250W，
优选100W至170W。
