The evolution of microstructure and mechanical properties at elevated temperature of cast Al–Li–Cu–Mg alloys with Ni addition

Journal of Materials Research and Technology, 2020
The effect of Ni content on the microstructure and mechanical properties at elevated temperature of cast Al–2.5Li–1Cu–1.5Mg–xNi alloys (x = 0, 0.2, 0.4 and 0.8 wt.%) was investigated.

Optimized Modeling Strategies for the Parametrization of a Two-Parameter Friction Model Through Inverse Modeling of Conical Tube-Upsetting Tests

Metals
Friction is a critical influencing factor for a variety of forming processes, as it affects, for example, the required forming force. Complex models for the numerical description of friction often have two or more model parameters but lack appropriate ...

A new integration of hot pressing and carbon partition process to produce high strength steel components with better toughness

MATEC Web of Conferences, 2015
A novel one step method for hot pressing and quench & partition (Q&P) integration – hot Pressing-dynamic partitioning (HP-DP) process is presented, which can be processed by regular hot pressing equipment and process. The HP-DP formed steel is an upgrade

Interphase Constituent of Laminated Composites Ti₄₆Zr₂₆Cu₁₇Ni₁₁

Journal of Aeronautical Materials, 2017
Thermal analysis of the Ti46Zr26Cu17Ni11 amorphous ribbon prepared by melt spinning was conducted by using DSC. Accordingly the amorphous alloy was treated by vacuum heat treatment at 693 K (< Tg), 753 K (Tg-Tx1) and 813 K (> Tx1) for different time to ...

Modeling of Tensile Tests Flow Curves Using an Explicit Piecewise Inverse Approach

Metals
Tensile tests are a common method for characterizing plastic behavior for sheet metal forming applications. During tensile testing at the beginning of the deformation, the stress state is uniaxial; however, as the deformation proceeds, the state changes ...
