In the present study, the effect of heat input of gas tungsten arc welding on the microstructure
and mechanical properties of AZ91 magnesium alloy was investigated. The microstructural …

It is of great significance in the field of engineering to repair the surface defects of ZM6 cast
magnesium alloy by an arc welding method. Compared with the traditional tungsten inert …

Stop magnezu EN-MCMgRE3Zn2Zr jest odlewany grawitacyjnie do form piaskowych.
Stosowany jest najczęściej w przemyśle lotniczym i samochodowym. Po procesie odlewania …

Hot cracking is one of the main problems involved in the casting of magnesium alloys and
their joining by means of welding. Despite many research done, this type of cracking still …

Due to low density and good strength properties, magnesium alloys are increasingly used
as a structural material They are used, amongst others, for large-size castings in sand …

In addition to aluminium and titanium alloys, the magnesium alloys comprise the group of
lightweight alloys which have the highest practical importance in structural applications. The …

In magnesium alloys castings, the casting defects such as shrinkage porosity often occur.
Such defects can be suppressed by repair welding or surfacing using a special filler rod …

This work, in combination with industrial tests of casting welding, shows that the causes of
high-temperature brittleness are the partial tears of the structure and the hot cracks of both …

Nowadays, magnesium alloys are used for casting into sand moulds of huge dimensional
castings, high-pressure castings and precise casings. In castings of magnesium alloys …
