“…At the same distance from interface, the diffusion content of elements increases, with the increase of liquid-solid volume ratio. At the distance −50 m from interface, the content of C and Cr in volume ratio of 12:1 was decreased by 21.6% and 24.7% comparing to volume ratio of 6:1, respectively The diffusion temperature and time have obvious effect on the interfacial microstructure of bimetal [16]. With the increase of liquid-solid volume ratio, the more heat energy can be imported to bimetal, leading to the improvement of diffusion temperature and time of elements.…”

“…The literature data show that compound casting is successfully used to join different metals or alloys to produce bimetallic castings such as steel/cast iron [10][11][12], steel/cast steel [13], steel/silumin [14,15] and Cu/Al [16]. This method seems to be the economic and promising to produce lightweight Mg-Al parts.…”

This paper discusses the joining of AZ91 magnesium alloy with AlSi17 aluminium alloy by compound casting. Molten AZ91 was cast at 650 o C onto a solid AlSi17 insert placed in a steel mould under normal atmospheric conditions. Before casting, the mould with the insert inside was heated up to about 370 o C. The bonding zone forming between the two alloys because of diffusion had a multiphase structure and a thickness of about 200 µm. The microstructure and composition of the bonding zone were analysed using optical microscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy. The results indicate that the bonding zone adjacent to the AlSi17 alloy was composed of an Al3Mg2 intermetallic phase with not fully consumed primary Si particles, surrounded by a rim of an Mg2Si intermetallic phase and fine Mg2Si particles. The bonding zone near the AZ91 alloy was composed of a eutectic (an Mg17Al12 intermetallic phase and a solid solution of Al and Si in Mg). It was also found that the compound casting process slightly affected the AZ91alloy microstructure; a thin layer adjacent to the bonding zone of the alloy was enriched with aluminium.

“…Research on low-carbon structural steels has been very active during the past several years because of the emphasis placed on the extensive application in the field of structures, automotive components, bridges and buildings [1][2][3][4]. To improve load bearing, recent approaches have been focused on developing low-carbon microalloyed steels with excellent combinations of fracture resistance and strength for given applications in order to reduce section size and weight.…”

In the present work, detailed studies were made on the optimization of microstructure and mechanical properties of a low-carbon microalloyed cast steel through control of heat treatment conditions. Specimens were austenitized at temperatures ranging from 950 to 1200 °C for 2 h followed by different cooling methods (furnace, air and water). For analyzing the effect of holding time on mechanical properties, some cast specimens were austenitized at 1100 °C for different times followed by furnace cooling. After heat treatment, mechanical tests were employed to evaluate the room temperature Charpy impact and tensile properties. The characterization of complex precipitates formed during heat treatment process was investigated by using analytical electron microscopy. The results show that dissolution of vanadium-containing precipitates plays an important role in the abnormal growth of austenite grains at 1150 °C. Further growth in austenite grains at 1200 °C is caused by the dissolution of Ti-containing particles and the reduction of the amount of precipitates. Correct selection of the austenitizing temperature, holding time and cooling method is very important to improve the mechanical properties of the steel. Heat treatment at 1100 °C for 2 h followed by furnace cooling leads to the best combination of excellent Charpy impact and tensile properties.
