摘要
材料基因工程的三大要素是:高通量计算,高通量实验和材料数据库。高通量实验不但可以加速建立材料成分–相–性能之间关系,从而快速建立和丰富材料性能数据库,同时也可用来验证材料计算理论模型的准确性。本文将介绍一些块体材料的高通量实验方法及应用实例,包括扩散多元节、快速合金成型法、激光近净成形技术、双圆锥台和梯度热处理等。利用这些技术,可以以并行的方式研究成分、应变、温度、冷速等的变化对块体材料相、显微结构、硬度、强度、塑性等性能的影响。期望可以为致力于块体材料高通量实验研究的同行提供一些参考。
The three essential factors of materials genome engineering are high-throughput computing, high-throughput experiments and materials databases. Not only can high-throughput experiments accelerate the establishment of the relationship between the composition, as well as phase and properties of material, therefore, establishing and enriching the material performance database, but also they can be used to verify material calculation models accuracy. This article will introduce some high-throughput experimental methods and applied cases of bulk materials, including diffusion multiple, rapid alloy prototyping, laser engineered net shaping, double cone and gradient heat treatment. Employing these technologies, the effects of composition, strain, temperature, and cooling rate on the phase, microstructure, hardness, strength and plasticity of the bulk materials can be studied in parallel manner. We expect to give some references for colleagues who are involved in high-throughput experimental research on bulk materials.
