Opis:: 2060-T8 Al-Li alloy was friction stir butt welded under natural and water cooling conditions. Microstructures and mechanical properties of the welding joints were mainly compared and discussed. By spraying water on the top surface of stir zone, the grain size was reduced, attributing to the improvement of microhardness. The maximum tensile strength under the water cooling reached 461.1 MPa. The joint fractured at the stir zone due to the thickness reduction and the joint softening. The fracture surface consisted of many dimples with various sizes, indicating the typical ductile fracture. The strategy to apply the low heat input at the welding stage and high cooling rate at the cooling stage during FSW is necessary to obtain a high-quality FSW joint.

Opis:: Present study describes about the effect of coolant water flow rate and coolant water temperature underside cooling slope on structural characteristics of casted AZ91 Mg alloy. Here, over the cooling slope, hot melt flows from top to bottom. Additionally, under the cooling slope, coolant water flows from bottom to top. Slurry gets obtained at bottom of cooling slope by pouring AZ91 Mg melt from top of the slope. Coolant water flow rate with coolant water temperature underside cooling slope warrant necessary solidification and shear to obtain AZ91 Mg slurry. Specifically, slurry at 5 different coolant water flow rates (4, 6, 8, 10, 12 lpm) and at 5 different coolant water temperatures (15, 20, 25, 30, 35°C) underside cooling slope are delivered inside metal mould. Modest coolant water flow rate of 8 lpm with coolant water temperature of 25°C (underside cooling slope) results fairly modest solidification that would enormously contribute towards enhanced structural characteristics. As, quite smaller/bigger coolant water flow rate/temperature underside cooling slope would reason shearing that causes inferior structural characteristics. Ultimately, favoured microstructure was realized at 8 lpm coolant water flow rate and 25°C coolant water temperature underside cooling slope with grain size, shape factor, primary α-phase fraction and grain density of 63 µm, 0.71, 0.68 and 198, respectively. Correspondingly, superior mechanical properties was realized at 8 lpm coolant water flow rate and 25°C coolant water temperature underside cooling slope with tensile strength, elongation, yield strength and hardness of 250 MPa, 8%, 192 MPa and 80 HV, respectively.

Opis:: The work is a continuation of research on the use of water mist cooling in order to increase efficiency of die-casting aluminum alloys using multipoint water mist cooling system. The paper presents results of investigation on crystallization process and microstructure of synthetic hypereutectic AlSi20 alloy. Casts were made in permanent mold cooled a with water mist stream. The study was conducted for unmodified AlSi20 alloy and a modified one with phosphorus, titanium and boron on the research station allowing sequential multipoint cooling using a dedicated program of computer control. The study demonstrated that the use of mold cooled with water mist stream and solution heat treatment allows in wide range for the formation of the microstructure of hypereutectic silumins. It leads to the growth of microstructure refinement and spheroidizing of phases in the casting.

The study demonstrated that the use of mold cooled with water mist stream allows the formation of the microstructure of hypereutectic silumins. A wide range of solidification temperature of hypereutectic silumins increases the potential impact of changes in the cooling rate on a size, a number and a morphology of preeutectic silicon and eutectic α+β (Al+Si).

Opis:: The work is a continuation of research on the use water mist cooling in order to increase efficiency of die-casting aluminum alloys. The paper presents results of research and analysis process, spraying water and generated a stream of water mist, the effect of the type of nozzle, the nozzle size and shape of the emitting of the water mist on the wall surface of casting die on the microstructure and geometry of water mist stream and cooling efficiency. Tests were used to perform high-speed camera to record video in the visible and infrared camera. Results were used to develop a computerized image analysis and statistical analysis. The study showed that there are statistical relationships between water and air flow and geometry of the nozzle and nozzle emitting a stream of microstructure parameters of water mist and heat the incoming stream. These relationships are described mathematical models that allow you to control the generating of adequate stream of water mist and a further consequence, the cooling efficiency of casting die.

Opis:: The work is a continuation of research on the use of water mist cooling in order to increase efficiency of the die-casting process for aluminum alloys. The paper describes the multipoint sequential cooling system of the casting die and its computer control and monitoring. It also includes results of the tests and analysis of cooling methods during making of the casting. These methods differ from each other in the sequence of casting die cooling and cause effective changes in microstructure and mechanical properties of castings made of AlSi11 alloy. The study demonstrated that the use of multipoint sequential cooling with water mist affects the microstructure refinement and reduces the segregation in the cast as well as more than by 20% increases the mechanical properties of castings in the rough state. The study also demonstrates that the sequential cooling of casting die accelerates the cooling of the casting and shortens die-casting cycle.
