Enhanced stress relaxation resistance of Cu–Ni–Si alloy strips through Sn addition and pre-aging treatment

open access: yesJournal of Materials Research and Technology
In this study, Cu-3.44Ni-0.86Si-xSn (x = 0, 1, 2 wt%) alloy strips were fabricated via two different processing routes, namely the traditional preparation (TP) process and the improved preparation (IP) process.

Studies on plants that hyperaccumulate copper, cobalt and nickel : their potential for use in phytomining and phytoremediation : a thesis presented in partial fulfillment of the requirements for the degree of Masterate of Science in Soil Science at Massey University [PDF]

open access: yes, 1998
This thesis reviews three lines of research on hyperaccumulators to examine their potential for phytoremediation and phytomining. The first line of research was to test the affect of nutrient addition on biomass and nickel uptake by two nickel ...

Optimizing Laser Ablation of Stainless Steels for Volume Removal and Surface Quality Using Burst of Pulses

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the ablation efficiency and surface quality of laser‐treated stainless steel alloys (AISI 304, AISI 420, and AISI 316Ti) using an ultrashort pulsed laser and varying burst parameters (MHz, GHz, and Bi‐burst). Both ablation rates and surface quality parameters are determined, including isotropy surface roughness values, highlighting ...

Micromechanical Insights into Sinter‐Based Additively Manufactured NiTi with Nb as a Sintering Aid

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the microstructural and micromechanical behavior of NiTiNb made through filament‐based materials extrusion via chemically correlated nanoindentation. B19' remnants from the original powder lead to Nb gradients within NiTiNb grains due to the short sintering times required in liquid‐phase sintering.

Low rate copper products to control Phytophthora infestans in potatoes in 2009 [PDF]

open access: yes, 2010
Between Dutch organic growers the late blight problems lead to discussions in which a temporary registration of copper products is also suggested. Some growers do not want any pesticides at all, while others see that biological potatoes from abroad are ...

Deformation Behavior of Optical Ceramic Nanomultilayers: The Role of Aperiodicity

open access: yesAdvanced Engineering Materials, EarlyView.
Ceramic nanomultilayers demonstrate optical and mechanical behavior tunability through aperiodicity. Within the studied systems, optically optimized coatings exhibit an average ultraviolet, visible, and near‐infrared spectral transmittance above 90%.
