块体非晶合金超塑性微成形

非晶合金超塑性微成形技术随着微细产品的兴起而诞生，由于非晶合金在常温下微尺度时具有极高的力学性能且在过冷液态区具有显著的超塑成形能力，在制备高性能微型零件方面具有广泛的应用前景。本文论述了几种典型非晶合金的玻璃转变温度和过冷液态区宽度及其在过冷液态区的力学行为，并在此基础上，分析了不同温度和应变速率对块体非晶合金成形结果的影响；同时，概述了块体非晶合金成形工艺，指出了存在的问题并进行了发展展望。

Super-plastic Micro-forming of Bulk Metallic Glasses

Technology of amorphous alloy superplastic micro-forming was born accompany with the prosperity of microproducts. Metallic glass has broad application prospects on fabricating high performance microproducts because of the excellent super-plastic forming ability in supercooled liquid region and mechanical properties in micron-size. Supercooled liquid region, time temperature-transformation and mechanical behavior of bulk metallic glasses in supercooled liquid region were introduced, based on that, the effects of different temperatures and different strain rates on the formability were analyzed. Meanwhile, the forming technology was described and existed questions were pointed out.
