dcterms:description
This work is concerned with assessment of thermomechanical properties of magnesium alloys which are used for manufacture of castings. In recent years, interest in and use of these materials in many industrial branches, of which transport equipment production plays a significant role, has been ever increasing. These materials find their place in construction and drives of many machines. In the case of use of castings which are subject to thermal stressing, we need to know mechanical properties of used materials at elevated temperatures. This paper gives analysis results of microstructure and mechanical properties of AZ91 magnesium alloy in the as-cast condition (F) and after heat treatment (T4). These materials were further compared with AM60 alloy which was cast into a metal mould. The paper deals with relative comparison of selected alloys cast into sand and metal moulds. There is a comparison of results of mechanical properties given for specimens tested at standard temperature and at selected elevated temperatures. The work was focused particularly on a region of above mentioned commercially delivered magnesium alloys and modified magnesium alloys used in Explat s.r.o. company operation, the Magnesium Alloy Foundry Division. These alloys were AZ91 ON, AZ91 Be in the as-cast condition and after heat treatment T4. Inoculation effect proved itself unambiguously positively on the observed strength characteristics, and that even in the case of casting into a metal mould. Improvement of mechanical properties of the cast structure was approved by heat treatment of selected alloys. A part of this work is an overview of the used foundry Mg alloys and trends in Mg alloy development.
