Open AccessHardening and overaging Mechanisms in an Au-Ag-Cu-Pd alloy with In additions
Hardening and overaging mechanisms were examined in a semi-precious Au−Ag−Cu−Pd dental alloy with small amounts of In, Zn and Ir. The alloy showed maximum age-hardenability at the aging temperature of 400°C. T...

Influence of interfacial reaction layer on reliability of chip-scale package joint from using Sn-37Pb and Sn-8Zn-3Bi solder
The microstructure of Sn-37Pb and Sn-8Zn-3Bi solders and the full strength of these solders with an Au/Ni/Cu pad under isothermal aging conditions were investigated. The full strengths tended to decrease as th...

Evaluation of internal structure and morphology of poly(benzyl ether) dendrimers by molecular dynamics simulations
We performed molecular dynamics (MD) simulations at 300 K on a series of poly(benzyl ether) (PBE) dendrimers having a different core functionalities. We used the rotational isomeric state Metropolis Monte Carl...

Effects of pore size, suspension concentration, and pre-sedimentation on the measurement of filter medium resistance in cake filtration
Theoretical and experimental study was conducted on the factors influencing the measurement of filter medium resistance by Ruth’s equation. It was determined that a filter medium having small pore size does no...
