Effect of Heat Treatment Temperature-Rate Parameters on Structure and Complex of Physical-Mechanical Properties in VST5553 Titanium Alloy Rod Semi-Finished Goods

Abstract:

VST5553 titanium alloy is high strength (α + β) - transition alloy which is used for the production of heavy-duty parts [1]. It is known [2], that the cooling rate changing during the heat treatment can change the phases ratio in the alloy. With regards to the VST5553 alloy, this may be due to different cooling rates over the cross section of large-sized semi-finished goods. This in turn affects a complex of properties. Thus, it is necessary to know the effect of the cooling rate of two-phase region on the structure and properties, particularly the VST5553 alloy. However, the research in this area is not sufficient enough. The present study is devoted to this issue.
