Characterization of the AZ31/AW-6060 Joint Fabricated using Compound Casting with a Zn Interlayer at Relatively Low Temperature Conditions

Popis výsledku v původním jazyce

The work deals with the fabrication of a joint between AZ31 magnesium alloy and AW-6060 aluminium allay with the use of a Zn interlayer. The Zn layer was produced on the surface of an AW-6060 alloy insert by diffusion bonding The insert was then placed inside a steel mould and kept at room temperature. The joint was produced using compound casting by filling the mould with liquid AZ31 alloy, heated to 650 degrees C. The microstructure of the bonding zone formed between joined alloys was analysed using an optical microscope and a scanning electron microscope equipped with an energy dispersive X-ray spectroscope. The properties of the joint were examined using Vickers microhardness measurements and simple shear strength testing. As a result of the experiment the 400 pm thick bonding zone with a complex microstructure was formed between the alloys. The microstructural analysis showed that the bonding zone reveals a high concentration of Zn and mg The layers of a eutectoid (a MgZn phase + a solid solution of Al and Zn in Mg), a Mg5Al2Zn2 phase and a Mg(Al,Zn)(2) phase with fine particles of other phases were observed there. The bonding zone was characterized by relatively high microhardness, which was related to the brittleness of the constituents The shear strength of the examined joint was 19.6 +/- 25 MPa.
