TheNanosteel®公司纳米结构材料设计的领导者今天宣布，该公司的工程粉末业务成功地扩展到增材亚博网站下载制造业。通过在激光烧结过程中利用其均匀的金属基质微观结构，该公司能够建立一个无裂纹的，完全致密的散装样品。Nanosteel最初在添加剂制造中的重点支持市场对按需，现场磨损零件的需求，同时解决了当前的3D打印高硬度零件的挑战。
NanoSteel’s breakthrough overcomes one of the major hurdles to achieving a high-hardness metallic part through additive manufacturing—the tendency to develop cracks during part builds. The company worked with a global process development partner to optimize processing of a proprietary NanoSteel alloy with a high volume fraction of borocarbide phases. This successfully produced a fully dense (99.9%) crack-free part with hardness values over 1000 HV, wear resistance comparable to conventionally manufactured M2 tool steels, and a uniform microstructure. Importantly, these properties were achieved without the need for post-processing such as hot isostatic pressing (HIP) or further heat treatment, reducing production cost and lead times.
Currently, the material options to produce highly wear-resistant parts through additive manufacturing are limited. By extending the reach of steel into markets currently served by WC-Co, ceramics, and other non-ferrous metal matrix metal composites, NanoSteel has the potential to generate cost-efficient wear parts to serve the tooling, mining, energy, and transportation industries in applications such as pumps, bearings, and cutting tools.
