Grider. The influence of thermomechanical processing variables on superplasticity in a High-Mg, Al-Mg alloy. Lee 1,Cited by: The specimens after thermomechanical processing were solution treated at °C for 2 h and quenched in water to ambient temperature, then aged at °C for 36 h. The processing parameters of the tested samples are shown in Table by:   Overall, the results indicate that thermomechanical processing of AM60 dramatically improves the tensile, fracture toughness, and fatigue behavior, making this alloy attractive for structural applications.

The reduced creep resistance after thermomechanical processing offers an opportunity for further research and by: 8.

EFFECT OF THERMOMECHANICAL TREATMENT ON TOUGHENING OF Al-Li-Cu-Mg-Zr ALLOY AND ITS TOUGHNESS M. Niinomi, K. Degawa, T. Kobayashi indicates the ductility, in contrast with the T6 process applied alloy F.

Therefore, ITMT process applied alloy D is smaller than that of the alloy F. Pm values of alloys. Influence of thermomechanical processing at temperatures above β-transus on the () process at temperature ºC (duration time, 3h) in the β-field to ensure the physico-chemical homogeneity throughout the alloy then cooled in water.

Thermo-mechanical processes Thermo-mechanical treatment processes consist of two processes. mechanical treatment process applied to AlZn5Mg3Cu alloy used in aviation industry. The optimal solution is determined by finding some values of independent variables, so that to obtain the best value for objective – function.

Objective function in the case of optimizing thermomechanical treatment regime studied is –File Size: KB. Supersaturated Cu-3at.% Ag alloy was processed by cold rolling and short-time annealing in order to achieve a combination of high strength and good tensile ductility.

After annealing of the rolled samples a heterogeneous solute atom distribution was developed due to the dissolution of nanosized Ag particles in some volumes of the matrix. In regions with higher solute content, Cited by: 2.

Effect of equal channel angular pressing (ECAP) at room temperature and subsequent annealing at temperatures ranging from to °C on microstructure, mechanical properties and electric conductivity of an Al-8%Ce alloy was examined It was shown that Al4Ce-type eutectic particles having plate-like shape break under ECAP; distribution of the particles appears to be more Cited by: 4.

A thermo-mechanical processing technique for reducing the transverse effect of high strength Al alloys is described. The technique, called Intermediate Thermo-Mechanical Treatment (ITMT) was applied to a high purity Al Zn Mg Cu, type by: The effect of magnesium content and different thermomechanical treatment regimes on structure formation for sheet aluminum alloy AA produced by twin-roll casting technology is.

Results are given for a study of the mechanical properties of aluminum alloy AA after thermomechanical treatment by different regimes, including different (in form and degree) cold plastic.

Laboratory-scale sheets of type AlMgMn alloys with varying Mg and Mn contents and additions of different amounts of Zn, Cu, Zr and Er were studied. The sheets were produced using two different cold-rolling degrees and two soft-annealing treatment procedures: air-circulated furnace annealing at °C with subsequent furnace cooling, and salt-bath annealing with Cited by: 1.

It turns out that the hardening effect is greater for programme D0,7 than for D5, and greater for alloy L 2 than L 1. The results show that, other conditions being equal, the copper content in AlMgSi influences hardening of the alloys (see Fig.

The hardening value of specimens of alloy L 2 after IA and IA+D is higher. This investigation was conducted to study the influence of off-axis deformation in the thermomechanical processing on the properties of Al–Li HT72 alloy sheet. The thermomechanical processing involved several stages.
