Abstract

In this work, several types of deformations (extrusion, one- and two-directional hot pressing) were applied to estimate the influence of regimes of deformations and annealing on characteristics of low-alloying Ru-bearing molybdenum (content of Ru is about 0.3 wt%). This study shows that a combination of extrusion and two-directional hot pressing leads to the formation of a more equiaxial microstructure of the material after annealing. The temperatures of full recrystallization of the studied alloy lie in the range of around 1300–1400°C, depending on the regime of deformation. The median values of grain size in fully recrystallized samples vary from 45 to 75 µm.

不同变形方式后高延展性低合金化含钌钼的特征

在这项工作中，几种变形类型（挤压、单向和双向热压）被应用于估计变形和退火对低合金化含Ru钼（Ru含量约为0.3 wt%）特性的影响。研究表明，挤压和双向热压相结合可以使材料在退火后形成更加等轴的组织。所研究的合金的完全再结晶温度在1300-1400℃左右，这取决于变形的状态。完全再结晶样品的晶粒尺寸中位数在45 ~ 75µm之间。

期刊介绍： The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
