通过简单且低成本的加工来制备大规模块体纳米结构材料是一个挑战。通过简单且廉价的自蔓延高温合成铸造路线，成功合成了具有80-100 nm层状共晶、尺寸为100 mm（直径）x 8 mm的大尺寸块状纳米结构Fe1.87C0.13（Fe-6.5 at.% C）材料。纳米结构Fe1.87C0.13材料在压缩测试中表现出高屈服强度（1300 MPa）和良好的延展性（接近40%）。讨论了纳米结构形成的机制。 (C) 2008 Acta Materialia Inc. 由 Elsevier Ltd 出版。保留所有权利。
It is a challenge to prepare large-scale bulk nanostructured materials by simple and low-cost processing. Large-scale bulk nanostructured Fe1.87C0.13 (Fe-6.5 at.% C) material with 80-100 nm lamellar eutectic and dimensions of 100 mm (diameter) x 8 mm has been successfully synthesized by a simple and inexpensive self-propagating high-temperature synthesis casting route. The nanostructured Fe1.87C0.13 material exhibits high yield strength (1300 MPa) and good ductility (similar to 40%) in compressive testing. The mechanism of nanostructure formation is discussed.
