In this research work, the nanostructured Fe-Mn (BM0), Fe-Mn-Cu (BM1), Fe-Mn-W (BM2), and Fe-Mn-Co (BM3) biodegradable alloys were successfully synthesized using mechanical alloying. The microstructure of the synthesized alloys was examined using XRD, SEM equipped with EDS, and HRTEM techniques. The results obtained based on these techniques confirmed the development of nanostructured BM0, BM1, BM2, and BM3 alloys and homogenous solid solutions with an even elemental dispersion. The compressibility of the synthesized alloys was investigated experimentally and empirically in the as-milled conditions and after applying a stress relief treatment (150 °C for 1 h). The load applied for compaction experiments ranged from 25-1100 MPa with a rate of 1 mm/min. According to the experimentation performed in the current study, the relative density of the as-milled BM0, BM1, BM2, and BM3 alloys was 72.90% and 71.64%, 72.32%, and 72.03%, respectively. After applying the stress relief treatment, the density was observed to increase to 75.23%, 77.10%, 72.65%, and 72.86% for BM0-S, BM1-S, BM2-S and BM3-S samples, respectively. A number of compaction models were tested to identify the optimum models for predicting the compressibility behavior of nanostructured Fe-Mn, Fe-Mn-Cu, Fe-Mn-W, and Fe-Mn-Co alloys in the as-milled and stress-relieved conditions.
在本研究工作中，采用机械合金化成功合成了纳米结构的Fe-Mn（BM0）、Fe-Mn-Cu（BM1）、Fe-Mn-W（BM2）和Fe-Mn-Co（BM3）可生物降解合金。使用XRD、配备EDS的SEM和HRTEM技术对合成合金的微观结构进行了研究。基于这些技术获得的结果证实了纳米结构BM0、BM1、BM2和BM3合金以及具有均匀元素分散的均匀固溶体的形成。在研磨态和进行应力消除处理（150℃，1小时）后，对合成合金的压缩性进行了实验和经验研究。压实实验施加的载荷范围为25-1100MPa，速率为1mm/min。根据本研究进行的实验，研磨态BM0、BM1、BM2和BM3合金的相对密度分别为72.90%、71.64%、72.32%和72.03%。施加应力消除处理后，BM0-S、BM1-S、BM2-S和BM3-S样品的密度分别增加到75.23%、77.10%、72.65%和72.86%。测试了多种压实模型，以确定预测纳米结构Fe-Mn、Fe-Mn-Cu、Fe-Mn-W和Fe-Mn-Co合金在研磨态和应力消除态下压缩行为的最佳模型。
