Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

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

Journal 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.

The role of collectors in the flotation of partially oxidised copper ores

, 2004
The effects of xanthates, dithiophosphates, dithiocarbamates and mixtures of these collectors on the froth flotation performance of partially oxidised and oxidised copper sulphide ores were investigated in this study.

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Effect of Ni/Sn ratio on microstructure and properties of Cu-Ni-Sn-P alloy

Scientific Reports
Cu-1.33Ni-1.35Sn-0.08P(Ni/Sn = 1/1), Cu-0.87Ni-1.82Sn-0.08P (Ni/Sn = 1/2) and Cu-1.78Ni-0.86Sn-0.08P (Ni/Sn = 2/1) alloys were prepared to explore the effect of different Ni/Sn ratios on the microstructure and properties of the alloys. The results showed
