难加工金属材料短流程高效制备加工技术研究进展

提出了难加工金属材料可以分为2大类的观点：一类是源于材料本征性能的难加工材料，具有高脆性，或高熔点、高变形抗力的特点；另一类是源于制备加工工艺复杂、成材率低的难加工材料。以作者课题组近年来的工作为基础，重点介绍了高硅电工钢、精密铜管、热交换用BFe10—1．1合金管材、高弹高导Cu-12％（质量分数）Al合金的短流程高效制备加工技术的研究开发进展情况。认为通过熔体和凝固过程的精确控制，可精确控制凝固组织和形状尺寸，是开发先进短流程制备加工技术的重要途径。

Development of Compact Processes for High Efficiency Fabrication of Hard-to-Working Metals

It is proposed that hard-to-working metals can be categorized into two types. One type originates from the intrinsical property of the metals, such as high brittleness or high melting point and high resistance to deformation. The other type originates from the complicated processing technique and low product yield of the metals. Based on the work of the author＇ s research group in recent years, the development of compact processes for high efficiency fabrication of high silicon steel, precision copper pipe, heat exchanger BFe10-1-1 alloy（C70600） tube and high performance Cu-12% （mass fraction）Al alloy was introduced substantially. It is also proposed that accurately controlling microstructure, shape and dimension of the products can be achieved through accurately controlling the melt and solidification behavior, which serves as a significant approach for the development of advanced compact process of metal processing.
