通过采用Fe-Si-B合金和渗碳体Fe 3C作为原料进行共同冶炼，冶炼过程中，Fe-Si-B合金中能够加入具有磁性的渗碳体Fe 3C，使得制备得到的非晶带材母合金的磁感应强度得以显著提升。当该非晶带材母合金用于制备非晶带材时，同样能够显著提高非晶带材的磁感应强度。
可以理解的是，当非晶合金为Fe-Si-B合金时，利用上述的制备方法制备得到的非晶带材母合金，其化学通式可以为Fe-Si-B-Fe 3C。
本申请实施例中，在提高非晶带材母合金的磁感应强度的前提下，为了保证利用该非晶带材母合金制备得到的非晶带材具有高强度、高硬度以及高塑性等性能，使Fe-Si-B合金与渗碳体Fe 3C的质量比为1:0.005-0.5，举例来说，可以是1:0.005、1:0.01、1:0.05、1:0.1、1:0.15、1:0.2、1:0.25、1:0.3、1:0.35、1:0.4、1:0.45、1:05等。
其中，所使用的Fe-Si-B合金与渗碳体Fe 3C均为本领域所常见的，对于Fe-Si-B合金来说，可以使其中各元素所占的原子数百分含量分别如下：Si 6at％-12at％、B 3at％-14at％、余量为Fe。
进一步地，该Fe-Si-B合金中，各元素所占的原子数百分含量还可以分别如下：Si 6at％-12at％、B 8at％-14at％、余量为Fe。
举例来说，本申请实施例可以提供这样一种Fe-Si-B合金，其包括以下原子数百分含量的各元素：Si 7at％、B 8at％、余量为Fe。
本申请实施例还可以提供这样一种Fe-Si-B合金，其包括以下原子数百分含量的各元素：Si 7at％、B 9at％、余量为Fe。
在另一种示例中，非晶合金除了包括Fe元素、Si元素和B元素之外，组成该非晶合金的元素还包括以下元素中的至少一种：Cu元素、Nb元素、Ni元素。
举例来说，该非晶合金包括但不限于：Fe-Si-B-Nb合金、Fe-Ni-Si-B合金、或者Fe-Cu-Nb-Si-B-Ni合金。
对于该示例中的非晶合金来说，使非晶合金与渗碳体Fe 3C的质量比可以为1:0.005-0.5，从而达到在提高非晶带材母合金的磁感应强度的前提下，保证利用该非晶带材母合金制备得到的非晶带材具有高强度、高硬度以及高塑性等性能。举例来说，非晶合金与渗碳体Fe 3C的质量比可以是1:0.005、1:0.01、1:0.05、1:0.1、1:0.15、1:0.2、1:0.25、1:0.3、1:0.35、1:0.4、1:0.45、1:05等。
对于渗碳体Fe 3C来说，其可以采用渗碳体Fe 3C成品，也可以采用白口铁来提供，白口铁中含有大量的渗碳体Fe 3C，并且成本低廉，可以作为较优选择。当然，还可以同时使用白口铁和渗碳体Fe 3C成品提供渗碳体Fe 3C。应用时，可以将白口铁和/或渗碳体Fe 3C成品与Fe-Si-B合金置于冶炼炉中进行冶炼。
本申请实施例中，可以在从熔过程中加入渗碳体Fe 3C，例如，将渗碳体Fe 3C加入含有Fe-Si-B合金的冶炼炉中。
对于非晶合金，其可以使用现成的成品(例如，常规Fe-Si-B合金成品，或者铁基非晶带材)，也可以在冶炼时进行制备。以Fe-Si-B合金举例来说，可以在冶炼炉中利用结晶硅、硼、铁进行直接熔炼，来获取Fe-Si-B合金。
在结晶硅、硼、铁直接熔炼制备Fe-Si-B合金的过程中，加入渗碳体Fe 3C，可以制备得到非晶带材母合金。
其中，上述举例中所加入的渗碳体Fe 3C可以包括渗碳体Fe 3C成品和/或白口铸铁。
在冶炼过程中，Fe-Si-B合金、渗碳体Fe 3C以及可选的渗氮体Fe 3N可以为粉末状形式，也可以为块状形式。
为了使形成的非晶带材母合金的成分更加均匀，本申请实施例中，非晶合金，例如Fe-Si-B合金和渗碳体Fe 3C均可以采用粉末形式。并且，该粉末的粒径可以控制在纳米级，例如5纳米至50纳米之间，举例来说，可以为10纳米、15纳米、20纳米、25纳米、30纳米、35纳米、40纳米、45纳米等。
Fe-Si-B合金的粉末，也称为超微晶合金粉末，或者纳米晶粉末，其与渗碳体Fe 3C的粉末可以采用本领域常见的破碎方式来获取。
以Fe-Si-B合金的粉末举例来说，其可以采用如下方法来获取：
将铁基非晶合金带材依次经脆化、热处理、机械破碎、气流破碎，获得Fe-Si-B合金的粉末。
在冶炼处理过程中，控制冶炼温度为1300℃-1500℃，例如1300℃、1350℃、1400℃、1450℃、1500℃等，以针对上述非晶合金获得更佳的冶炼效果。
冶炼时间根据非晶合金和渗碳体的量来确定，可以为12小时-24小时等。
另一方面，本申请实施例提供了一种非晶带材母合金，该非晶带材母合金采用上述的任一种制备方法制备得到。
本申请实施例提供的非晶带材母合金，基于在非晶合金中加入渗碳体Fe 3C，由于渗碳体Fe 3C具有磁性，使得非晶带材母合金的磁感应强度(也称磁通密度 或B值)得以显著提升。当该非晶带材母合金用于制备非晶带材时，同样能够显著提高非晶带材的磁感应强度。
作为一种示例，该非晶合金包括但不限于：Fe-Si-B合金、Fe-Si-B-Nb合金、Fe-Ni-Si-B合金、Fe-Cu-Nb-Si-B-Ni合金等。
本申请实施例提供的非晶带材母合金可用于制备高磁感应强度的非晶带材。
在利用本申请实施例提供的非晶带材母合金制备非晶带材时，还可以在喷带之前再次加入一定量的渗碳体Fe 3C进行重熔，且重熔温度控制在1300℃-1400℃之间，如此更加利于非晶带材的磁感应强度的提高。
本申请实施例所涉及的方法中，非晶合金可以是铁基非晶合金，也同样适用于铁镍基非晶合金、钴基非晶合金，即，可以使铁镍基非晶合金或者钴基非晶合金与一定比例的渗碳体Fe 3C、以及可选的渗氮体Fe 3N一起冶炼，获得对应的母合金。
以下可通过具体示例进一步描述本申请：
