摘　　要：铜模铸造作为制备非晶合金的主流技术,是一种简单、易于操作、使用广泛的技术。由于尺寸大小的影响,限制了非晶合金的应用。激光增材制造作为一种新的制备非晶合金技术,可以突破尺寸的限制。本文利用激光增材制造技术制备了10mm×10mm×3mm的块体Zr_(41.2)Ti_(13.8)Cu_(12.5)Ni_(10)Be_(22.5)非晶合金,对其微观组织和力学性能进行分析,与铸态的Zr_(41.2)Ti_(13.8)Cu_(12.5)Ni_(10)Be_(22.5)非晶合金形成对比。研究结果表明,成形试样非晶率可以达到96.95%,存在少量晶体相,抗压强度为992 MPa,在力学性能上低于铸态的非晶合金,但为辅助铜模铸造制备非晶合金突破尺寸限制提供了一个新思路。Copper mold casting,the mainstream technology for preparing amorphous alloys,is characterized by its simplicity,ease of operation,and widespread utilization.However,the application of amorphous alloys is constrained by size limitations.Laser additive manufacturing,emerging as a novel technology for amorphous alloy preparation,has the potential to overcome these limitations.This study employs laser additive manufacturing to fabricate a 10mm×10mm×3mm bulk Zr_(41.2)Ti_(13.8)Cu_(12.5)Ni_(10)Be_(22.5)amorphous alloy,analyzing its microstructure and mechanical properties in comparison with the as-cast counterpart.The findings reveal that the amorphous fraction of the fabricated sample reaches 96.95%,with a minor presence of crystalline phase.Although the compressive strength measures 992 MPa,slightly lower than that of the as-cast amorphous alloy,this method offers a pathway to assist copper mold casting in preparing amorphous alloys that surpass size limitations.
