Phase stability of hcp-Mn-Al (epsilon-phase) was found to improve by carbon addition. MnxAl100-xCy (50 <= x <= 63 and 0 <= y <= 2) samples were prepared by reactive sintering method. The annealing and quenching of the samples were carried out for 700 to 1100 degrees C. The ...
摘要: 在周国治的通用模型基础上,采用了以往作者在Fe-Mn,Fe-Si及Mn-Si系的多余自由能及磁性能数据;SGTE的点阵稳定参数,计算了Fe-Mn-Si系的fcc相和hcp相的吉布斯自由能,并依此计算了不同成分的Fe-Mn-Si合金的T_0温度.会议名称: 《第九届全国相图学术会议论文集》 ...

Very recent, accurate dilatometric measurements of the fcc<->hcp martensitic transformation (MT) temperatures are used to develop a new thermodynamic description of the fee and hcp phases in the Fe-Mn-Si system, based on phenomenological models for the Gibbs energy function. The composition depende...
he obtained results shown that the HCP ε-FeMn alloy of the Fe-20 %Mn-0.05 %C type deformed by HE undergoes brittle DF along the boundaries of initial austenitic grains. A decreased resistance of alloy extrudates to DF is due to a high-intensive γ→ε-MT with a certain stabilization ...
