Abstract Obtaining a strong bond between aluminum and steel is challenging due to poor wettability melt brittle intermetallic phases forming in the interface. In this research, novel coating method, namely hot dipping of Sn, has been developed treat insert surfaces. Results show that without preheating mold or Sn-coated insert, thin, crack-free, continuous metallurgical bonding layer was achiev...

Two solution-based methods, metallo-organic decomposition and sol–gel processes, were used to study the effects of precursor solution type on the microstructure evolution and texture development of oriented PZT films. Microstructure development and perovskite content are strongly dependent on the heating rate. Fast heating rate forms a dense fine-grained microstructure with (111) orientation. I...

Vibration was adopted to enhance the interface bonding of Mg–Al bimetal prepared by lost foam compound casting (LFCC) technique. The bimetallic composed three layers: layer I (Al3Mg2 and Mg2Si phases), II (Al12Mg17 III + δ-Mg eutectic structure). With increase in vibration acceleration, cooling rate increased, resulting decrease reaction duration that generates intermetallic compounds (IMCs) (i...

Thermomigration experiments were conducted to study the change in mechanical properties of 95.5Sn–4Ag–0.5Cu (SAC405) lead-free solder joint under high temperature gradients. This paper presents some observations on samples that were subjected to 1000°C /cm thermal gradient (TG) for 286 h, 712 h, and 1156 h. It was observed that samples subjected to thermal gradient did not develop a Cu3Sn inter...

It has long been known that solute segregation at crystalline defects can have profound effects on material properties. Nevertheless, quantifying the extent of solute segregation at nanoscale defects has proven challenging due to experimental limitations. A combined experimental and first-principles approach has been used to study solute segregation at extended intermetallic phases ranging from...

The search for new hard materials is often challenging, but strongly motivated by the vast application potential such materials hold. Ti3Au exhibits high hardness values (about four times those of pure Ti and most steel alloys), reduced coefficient of friction and wear rates, and biocompatibility, all of which are optimal traits for orthopedic, dental, and prosthetic applications. In addition, ...

The first-principle calculations were performed to investigate the structural, mechanical, electronic and thermal properties of the binary ductile intermetallic compound CeAg with B2 (CsCl) structure. The calculated value of lattice constant a0 for CeAg with generalized gradient approximation is 3.713 Å, which is in better agreement with experimental data than local spin density approximation. ...
